Interview | The "New Force" of Quantum Computing? Magnetic Sigmon can be used as a kind of qubit.

Recently, Christina Psaroudaki, a researcher at California Institute of Technology, and Christos Panagopoulos, a professor at Nanyang Technological University, put forward the idea of using Sigming as qubit, and said that it has advantages in practicality and scalability.

The research paper was published in Physical Review Express on August 4th, local time, titled "Skyrmion qubits: a new class of quantum logic elements based on nanometer magnetization".

"Quantum computing is expected to significantly improve computing power through the inherent characteristics of quantum mechanics, surpassing today’s supercomputers." In an exclusive interview with The Paper (www.thepaper.cn), Psaroudaki said, "Quantum computers are based on qubits, which are represented by the special quantum state of a physical system. Unlike the 0 or 1 of classical bits, quantum bits can also be in the so-called superposition state-that is, both 0 and 1. In order to realize quantum computers, many different candidates are currently being sought. "

The paper shows that the core of quantum computing is qubit made of very small particles such as atoms, ions or electrons. At present, superconducting circuit is one of the leaders of noisy medium-scale quantum computing scheme. Its size is macroscopic, but it has perfect quantum characteristics. Although superconducting quantum has made great progress, there are still great challenges, especially in control and scalability.

In magnetic materials, when the spin orientation of local atoms deviates, a quasi-particle with vortex structure will be produced, which is called magnetic sigmon. The properties of this quasi-particle can generally be described by topological charge or helicity.

"Sigmon has 1/2 spin, so it can be used as a qubit. Because of its good stability, controllability and measurability, it can be used as a logical qubit in quantum computing. The so-called logical qubit refers to the unit that can realize the function of qubit logically and consistently, and the physical deviation and failure probability have little influence. " Zhao Yukang, an industry expert of Guo Dun Quantum, told a reporter from The Paper (www.thepaper.cn).

"Magnetic Sigming can be very small, reaching the nanometer level, and it is a candidate for the next generation of information storage and logic technology. Magnetic Smirnology is a field that deals with the development of classical Smirnon spintronics, and it has developed into a huge and active research field. " Psaroudaki said, "An important feature of our proposal is to accelerate the development of Sigmund quantum bits by using the knowledge and the most advanced technology in the field of Sigmund. The knowledge and technology of Sigmund can be directly used and transferred to our proposed platform, and it provides advantages in practicality and scalability. "

Sigmon qubit

The scheme proposed by Psaroudaki and Panagopoulos is to realize qubits by using stable magnetic sigmons bound in magnetic nano-disks, and to connect different magnetic nano-disks by using electric fields.

By applying the electromagnetic field, the discrete energy levels in the quantized energy spectrum of the magnetic Sigmon can be controlled, so that the helicity between different energy levels can be changed, and these two energy levels can be encoded into two quantum states |0 > and |1 > of the qubit. In addition, the electromagnetic field can be tuned to control the coherence time of qubits. In this design, the quantum bits of adjacent magnetic nano-disks can also be coupled with each other, thus realizing two-bit quantum gate operation. Finally, the reading operation of quantum information can be completed by using a high-sensitivity magnetometer.

A member of the domestic quantum team gave a detailed introduction to the reporter of The Paper (www.thepaper.cn) on how the magnetic sigmoid in this research is used in quantum computation. He said, "This paper uses the quantum computation of the spin angle φ in the XY plane, a quasi-particle of magnetic sigmoid. According to the different parameters, it is divided into two bit theory designs. "

"The first is to encode the qubit state by using the deviation of the spin component in the z direction from the equilibrium state, and the deviation of 0 or 1 represents the 0 or 1 state of the qubit respectively. This design is similar to the charge qubit in superconducting bits, and the bit state is encoded by the number of charges on the island. The second is to encode the qubit state by using the rotation angle of spin in XY plane. The two angles in opposite directions represent the zero state or the one state of the qubit respectively. This design is similar to the magnetic flux bits in superconducting bits, and the quantum bits are encoded by clockwise and counterclockwise currents. " The member said.

Psaroudaki said that because the sigmons can be manipulated by electric and magnetic fields, the quantum bit properties of multiple sigmons are configurable and can be optimized. This includes logical qubit state and qubit lifetime, which are very important to realize stable and reliable qubits and can perform various logical operations. "Our work shows that the Sigmund quantum bit is very attractive as a logical element of quantum processor, and it is coping with the key challenges of quantum bit technology-control and scalability."

The paper shows that scalability, controllability of microwave field, operating time scale and non-volatile readout technology are all together, which makes the Sigmund qubit very attractive as a logic element of quantum processor.

At present, Psaroudaki and Panagopoulos have found several candidate materials, which can be used to design artificially adjustable magnetic Sigmon qubits. They predict that with the development of research, more materials will emerge in the future to realize this kind of magnetic sigmoid qubit.

When talking about the prospects and challenges of Sigmund in the field of quantum computing, Psaroudaki said, "Our work is at the intersection of two unrelated research directions-the quantum bit field and the Sigmund field. The former aims at developing quantum computers, while the latter aims at designing future spintronics devices based on magnetic Sigmund. Our idea has introduced a new direction in the field of Siegel electronics and nano-magnetism, and opened up an undeveloped way for quantum computing. The challenge now is practicality, that is, designing architecture for specific functions. "

"This paper constructs quantum bits on two-dimensional magnetic materials, which is really meaningful in physics and creates a new realization method of quantum computing. However, because this is a relatively theoretical article, the discussion of single-bit self-state, single-bit manipulation, inter-bit coupling and bit state reading still stays at the physical level, not at the actual design level. " The aforementioned members of the domestic quantum computing team said.

Zhao Yukang said, "The work of this paper is to experiment the logic gate manipulation ability of a single sigmoid, which is a new possible route of quantum computing, but there is still a gap from the realization, such as the coupling that has not been extended to multiple sigmoids, and the verification of the deterministic manipulation and long-term retention ability of logical qubits is not sufficient."

"Hot Search" Tianjin roadshow audience praised: evil does not suppress positive blood boiling.


1905 movie network news The film directed by, starring, and starring is being shown. A few days ago, the closing station of the national roadshow of Hot Search "Sound All the Way" came to Tianjin University of Technology, and director Xin Yukun and actor Song Yang came to the roadshow to communicate with the students after the show.

 

In the movie, the girl who should have been at the "desk" was sent to the "wine table", but the girl who sought to speak was framed by the capital crocodile, became the victim of covering up the truth, and was pushed to the center of the topic and jumped off the building under the pressure of public opinion … … A series of shocking female dilemmas have made the audience sigh, "particularly empathetic."


After watching the movie, a female audience said that they were deeply touched by Zhang Xiaoying’s experience. "She is unfortunate and I am lucky." She also said that at the end of the movie, everyone stood up for her and was very moved. "I hope all girls can be their own superheroes, and they can bravely say no when they encounter things they don’t want or like."


After watching the movie, some students mentioned the control group of Amy Zhen Xi and Zhang Xiao Zhen Yu Tian in the movie, saying that they could feel Amy’s helplessness. Xin Yukun, the director, said, "This is a feature of changing times. The victim psychology like Amy is common, and Zhang Xiaoying’s mother will also block her daughter’s voice because of the traditional concept, so that the accumulation of ideas will make more Wang Shimin people reach out to young girls. The significance of Chen Miao is to break this vicious circle."


At the scene, another student noticed the book Rules throughout the film, saying that "the established rules may be wrong. If someone comes forward to question, we should think about whether what he proposed is the real rules". Director Xin Yukun responded, "Chen Miao, as a skeptic and a media person, finally wants to wake up the former victims through the media, let them unite and complete the attack on Wang Shimin through legal weapons, and the law is the sword that can finally sanction Wang Shimin".


A student who experienced cyber violence was touched by the movie. "I feel the same for the story in the play. If everyone is willing to speak, then the impossible will be completed in the end." If public opinion, society and law are twisted into a rope, I believe there is nothing that cannot be solved. " Director Xin Yukun praised everyone, "In the complex online world, if we really encounter something, we can make people stop being silent through law and public opinion, and there is a good result. This is our original intention of creation".


Is it okay to open the skylight after it rains?

When driving in rainy days, it is not recommended to open the rear sunroof. This is because doing so may cause damage to the electronic control mechanism of the sunroof, and may also cause rainwater to enter the car, thus damaging the electronic system in the car.

The skylight of a car is a convenient function, but improper use may cause damage to the car. Therefore, when driving in rainy days, it is best to close the skylight to prevent rainwater from infiltrating into the car. In addition, be careful not to turn on the external circulation of air conditioner in rainy days, because this will lead to water in the car, which will affect the air quality and health in the car.

If you are not sure whether you can open the sunroof, it is recommended to check the owner’s manual of the vehicle or consult a professional technician. They can provide more specific suggestions to ensure that your vehicle is in good condition when driving in rainy days.

In a word, when driving in rainy days, we should pay attention to protecting all parts of the vehicle to ensure its normal operation. Closing the skylight and avoiding opening the external circulation of air conditioner are important measures to protect the safety of vehicles and passengers.

Have you ever eaten the pineapple that grew up in the sea?

Watch the pineapple grow up in the sea.
This is HainanDuoge villageA pineapple field ↓
Unlike other places, this fielddepend onLanding on the seaThe pineapples in the field grew up watching the sea. What’s the smell of pineapple growing up in the sea?

00:54
Our reporter Gong Baichao tasted it for everyone.Sweet with a little saltIt tastes a little fresh. Eating this pineapple, it is estimated that you can avoid the step of soaking in salt water.
Everyone knows that Hainan Island is "Tropical waterfruitParadiseDuoge Village, located in the eastern part of Hainan Island, is also fragrant with fruits all year round, with coconut, banana, longan and other fruits dazzling.
Among the fruits rich in Duoge Village, the most famous one is the number.pineapple.
Almost every family here grows pineapples, and the planting area isMore than 10,000 muThe output value created is as high asMore than 30 million yuanThe per capita annual income of villagers is close.20,000 yuan.
By planting pineapples, the villagers lived in two or three-story buildings and drove private cars. The money for children to go to school was also earned by planting pineapples.
Qiaoxiang Duoge
Duoge village is a village withMore than 300 years of historyThe village.
In the early years of Qing Dynasty, the Tseng brothers and their clansmen migrated from Fujian coast to Shanqin Bay in Hainan, and gradually formed villages. At that time, people still used offshoreFishing for a living.
In order to make their families live a better life, many villagers began toAway from home, across oceans.Go to Singapore, Malaysia and other places to work hard. Duoge Village has thus become a famous place in Wanning.village or town inhabited by relatives of overseas Chinese and returned overseas Chinese.
Pineapple opens the way to wealth.
The pineapple cultivation in Duoge Village is fromMore than 30 years agoIt started.
In the late 1980s, when villager Zeng Xianruo went to Wenchang to sell seafood, he found that there were many stalls selling pineapples.
At that time, pineapples were relatively rare in Hainan, so out of curiosity, he asked how much they cost.80 cents a cattyThe price really surprised him.
At that time, the hairtail he sold was only 45 cents, and the price of this pineapple almost caught up with that of hairtail.double;twofoldYes.
Zeng Xianruo thinks that this is achance.
At that time, there were few places to grow pineapples, and their villageClimatic conditions, soil environmentSimilar to Wenchang, if pineapples can be planted, the future development will bevery promising.
After returning to the village, he immediately discussed it with the big guy.
But at that time, most of the fields in the village were planted with crops such as pepper and rubber. If you want to plant pineapples, you can onlyCut down the pepper tree. And at that time, pepperHarvest periodIt’s almost there. It’s a pity to cut it down.
Is it to keep the pepper tree steady, orGet ahead of most peoplePineapple was planted, and finally Duoge village people chose the latter.
People cut down pepper trees, reclaimed more than 100 acres of land, and planted Duoge Village.The first batch of pineapple seedlings.
Many people in the village still remember that year, before the harvest season arrived, the consignee came to buy it. At that time, the output value of pineapple per mu was about 2000 yuan, and 100 mu of land was20More than ten thousand yuanThe income is almost pepper.Two or three times..
hang onThink about change and seek innovation.The idea that the pineapple planting area in Duoge Village is getting bigger and bigger, and the villagers made money by planting pineapples. By the early 1990s, there were many pineapples in the village.wealthy family",and Duoge Village has become famous"pineapple village”。
Thinking about change and seeking innovation can be long-term
However, in the next twenty years, Duoge Village was oncego no further.invariableThe planting mode has made the pineapple industry in Duoge Village graduallyLose an advantage.
In 2017, Duoge Village suffered an unprecedentedselling crisis.
That year, due to the abnormal climate, the ripening time of pineapples was advanced, and many pineapples were produced and Guangdong pineapples were produced.Simultaneous listingAt that time, fresh fruits piled up and the marketoversupply.
At that time, there were yellow pineapples all over the mountains.Unmanned harvesting. The villagers were in a hurry, but there was nothing they could do.
Fortunately, at that time, the Wanning Municipal Government issued the relevant emergency subsidy scheme, and gave transportation subsidies to the distributors who came to Wanning to buy pineapples, which reduced the losses of fruit farmers.
After the crisis, the villagers realized their own shortcomings. In order to broaden their horizons and ideas, they went out of the village and visited various places.
After some discussion, they decided to take advantage of Hainan’s climatic advantages and plant.Off-season pineapple.
To this end, they invited.Expert guidanceAfter more than a year of careful management, the first batch of out-of-season pineapples matured in August 2020, and once the fresh fruit was launched, it wassold out.
Scientific planting and high-quality development
With the development of Duoge Village getting better and better, many young people also choose to return to their hometowns to start businesses after graduating from college. Li Ruchao is one of them.
At first, Li Ruchao sold tropical fruits in his hometown through e-commerce platform. In the process of sales, he found thatBoutique fruitIt has gradually become a market consumption trend.
So he was born.Do fine agriculture and science and technology agriculture.The idea.
In 2020, with the support of the local government, Li Ruchao built a pineapple base in Duoge Village.Modern digital farm.
Through the data collected by sensors in digital farms, you canGuide field management. When to fertilize and when to water, there are more scientific operating standards.
From relying on the weather to relying on the development of science and technology, Duoge village people are constantly seeking innovation and change, and the small village is moving towards a happier future.
At 20:00 tonight, walk into Duoge Village in Hainan and realize pineapple freedom!

Summary of Registration Time and Entrance of Self-taught Exams in April 2024 by Provinces

It’s not just the office workers in the three northern counties who are in Beijing.

"This is what class? I just got off work when I arrived at work … "In recent days, photos of Yanjiao, Dachang and other severely congested checkpoints in Beijing have been frequently screened in Weibo and WeChat circle of friends.
Let’s take a look at the comments of netizens ~ ~ ~
Beijing checkpoint: there are so many people as if they are in a popular scenic spot.
On March 9, another Monday after the resumption of work, a video of the crowd congestion at the Baimiao checkpoint from Yanjiao, Hebei Province, sparked heated discussion after it was spread on social platforms. In the 12-second video, many people wearing masks lined up at the checkpoint waiting for inspection, and the crowd could not see at a glance. It is reported that the time for vehicles to pass through checkpoints is as long as 2 to 4 hours. Before the epidemic, it only took half an hour for vehicles to pass.
There are two main checkpoints from Yanjiao to Beijing, one is Baimiao South checkpoint at Tongyan Expressway intersection, and the other is Baimiao North checkpoint on the old Beijing-Yushu line. Baimiao North Checkpoint is located on the national highway, and the people who have been inspected from this station mainly go to the subway station or the Beijing City Sub-center to work.
The same congestion also occurred at the checkpoint of Friendship Bridge in Dachang.
Hu Xiao, who lives in Chaobai Peacock City Community of Dachang, works in a company in Beijing’s North Fourth Ring Road. On March 9, at 5 am, Hu Xiao got up early and went out to work after washing. As a result, he was stuck in the Friendship Bridge for nearly 2 hours, and it was close to 10 am by the company. Hu Xiao said that the traffic jam at the checkpoint is not so serious at ordinary times, but it takes two hours at most from home to the company. "From the community, after two traffic lights and 500 meters to the checkpoint of Friendship Bridge, the traffic jam began, and the car went ahead like a snail, queuing for nearly two hours, and passing through the checkpoint of Dachang to check the ID card and take the temperature. The first level has passed, and there is a second level. After crossing the bridge, the Tongzhou checkpoint arrived, and the identity card was also checked and the temperature was measured. The cars at the bridgehead were one after another. " Just a week ago, the Friendship Bridge was still very "friendly". The Friendship Bridge carried many people’s dreams of going to Beijing.
As the northern drifters who live in Yanjiao, they are no strangers to the traffic congestion in Beijing every Monday. However, on Monday, March 9, friends in Yanjiao were still stunned by the unprecedented congestion in the "three northern counties" including Yanjiao, and there was no relief in the morning of March 10.
Where are the three northern counties?
You can understand it with two maps.
In Hebei, there is a saying of "three northern counties". The so-called "North Three Counties" refer to sanhe city, Dachang Hui Autonomous County and Xianghe County under the jurisdiction of Langfang City. These three counties and cities are administratively affiliated to Langfang City, Hebei Province, but they have been wrapped up by Beijing and Tianjin and become "enclaves" in Hebei. (In the picture above, the "enclave" sandwiched between Beijing and Tianjin is the three northern counties. ) The special geographical location makes it a special economic zone in Hebei and the nearest "back garden" in Beijing. Yanjiao, which we are most familiar with, belongs to Sanhe, and Xianghe Furniture City and Xianghe Meat Pie, which we are familiar with, are all "specialties" of the three northern counties.
Under the epidemic, the three northern counties were so congested in Beijing. In order to save time to the greatest extent, many office workers from Yanjiao to Beijing choose to walk to Baimiao Village and then transfer to public transportation. People who go to work must get up early if they want to attend work normally. Some netizens reported that traffic jams began at 5 o’clock in the morning, and people walking after dawn were comparable to tourist attractions during the long holiday.
A Beijing office worker who lives in Tianyangcheng Community in Yanjiao sighed with emotion: "It took me three hours to get out of Yanjiao on the morning of the 9th, and the expressway simply didn’t move. Originally, I took the main road of the national highway, which was closed to traffic, and finally took the auxiliary road, bypassing Yanshun Road. Originally, the traffic volume was large, and the result was even greater. Before arriving at Baimiao checkpoint, all the passengers on the bus got off to check their ID cards and take their temperature. There were people sticking up in the queue at the end. The office worker said that everyone knows that in an emergency, we should keep our distance and cherish life, but we can’t do it at all. Finally, he arrived at the unit at 11: 40, and at that time, the canteen of the unit just started to eat.
"There are more and more people traveling to work like me in Yanjiao now. Driving or carpooling is too blocked, and time is not guaranteed." Song Ran, who lives in Yanjiao, said that when passing through the checkpoint, you need to take your temperature and check your ID card. He works in Gongzhufen himself. During working days, he needs to ride an electric car for 25 minutes to Lucheng subway station of Metro Line 6, and then take the subway for 1 hour and 15 minutes to Gongzhufen. Song Ran said that the most blocked journey to work he has experienced so far is March 9, and it took him five hours to carpool to work.
Another fact that office workers in Beijing have to face is that after the outbreak of the epidemic, the buses in the three northern counties have basically stopped. At present, there is only one bus No.818 in Yanjiao. According to media reports, on March 4th, the passenger volume of bus No.818, the only bus line between Beijing and Hebei, reached 10,025, which was the first time since it resumed operation on February 3rd. Because of fear, many office workers in the three northern counties can only choose other ways or drive to Beijing.
Under the epidemic, private cars are undoubtedly the most reassuring means of transportation for office workers. However, passengers have to queue up to walk to the checkpoint, take their temperature, check their identity cards, check their work permits in Beijing, etc., and also check the trunk.
A media person who lives in Yanjiao and works in Beijing said that the health check-up in Beijing is to strengthen epidemic prevention, but the risk caused by the early check-up on March 9 is probably higher than the risk it is committed to eliminating. On the whole, inspection in Beijing has played a positive role in all kinds of security in the capital, but the current situation has put unbearable pressure on the routine inspection system, so it is the proper meaning of people-oriented urban governance to carry out emergency adjustment. Beijing’s strict prevention and control must not be lost to the continuous congestion and gathering in the three northern counties these days.
When will the problem of difficulty in entering Beijing be solved?
The comprehensive checkpoint of Baimiao South, Tongzhou, Beijing, allows most vehicles from Yanjiao, sanhe city to enter Beijing. For the 100,000 inter-provincial office workers who live in Yanjiao and work in Beijing, it is necessary to ensure the safety of epidemic prevention and the efficiency of returning to work. "People who can punch in on time and go home safely are equivalent to fighting monsters in the game and winning the final victory." "This is working with life." Netizens from Yanjiao joked helplessly on the Internet.
The police on duty at the Joint Service Police Station of National Highway 102 of sanhe city Public Security Bureau said that there are more than 5,600 vehicles entering Beijing in the morning rush hour every day, which has returned to about 80% of the normal traffic. They have to take the temperature of each passenger and check the identity information.
In fact, the public security department in Tongzhou District of Beijing has repeatedly added police force to the checkpoint, but with little effect. Many office workers in Beijing who live in three northern counties are eager to introduce the New Deal quickly to help them solve this urgent need.
In fact, as early as a few years ago, some netizens reported the congestion problem of Yanjiao in Beijing through channels such as leadership message boards on relevant websites. On August 1, 2019, the Beijing Municipal Commission of Communications published the Planning for the Construction of Comprehensive Highway Checkpoints in Beijing (2019-2035). According to the planning requirements, a total of 75 comprehensive checkpoints were planned, including 44 existing comprehensive checkpoints and 31 planned new ones.
Among the 31 new stations, there are 3 new checkpoints in Tongzhou. One checkpoint will be completed this year and the other two will be completed in 2022.
The Beijing Sub-center moved eastward to Tongzhou, and the three northern counties ushered in the opportunity of coordinated development with the Beijing Sub-center. Previously, the plan to realize the "Four Unifications" between Beisan County of Langfang and Tongzhou District of Beijing has been reported to the Beijing-Tianjin-Hebei Collaborative Development Leading Group, and Beisan County and Tongzhou of Beijing formally implemented the "Four Unifications" (that is, unified planning, unified standards, unified policies and unified management and control).
Now, it is time to solve the problem of "difficulty in entering Beijing" in the three northern counties.
"It is necessary to avoid the inspection of the entrance to Beijing in the three northern counties. What I mean here is not to check carefully, but to face thousands of people who have to go to work on their way with the average screening of needle in a haystack. Beijing, Tianjin and Hebei are already quite safe areas. Except for imported cases, there are few new local cases. At this time, in order to be absolutely safe, it will become a kind of’ relative formalism’ to face the huge flow of people to work by dealing with a small number of people during the peak period of the epidemic. " Hu Xijin, a media person, said.
On the afternoon of March 9th, the thirty-ninth meeting of the leading group for the prevention and control of epidemic situation in COVID-19, Beijing and the eighth meeting of the coordination mechanism for joint prevention and control of strict management in Beijing were held. The meeting stressed that it is necessary to increase inspection channels at checkpoints in Beijing to prevent queues from being crowded. In crowded places such as supermarkets and hypermarkets, epidemic prevention measures should be strictly implemented. Give full play to the role of "health treasure" in resuming work and production. It is necessary to attach great importance to safety in production during the epidemic prevention and control period, and strengthen safety inspections at centralized medical observation points and sites and enterprises that have resumed production to prevent safety accidents.
Some insiders suggest that because there are a large number of people working in Beijing in Yanjiao and other three northern counties, bringing these areas into the prevention and control system of the capital is probably one of the solutions to the problem. It is necessary to formulate a quick passage method for people who need to travel to and from the capital and the three northern counties every day to avoid them having to check every time they pass.
Search the city for more than one time: strictly control Beijing in many places.
On March 9, the Shenyang Epidemic Prevention and Control Command issued Order No.8, which proposed to strictly implement the regulations on entering Beijing, further strengthen the management of entering Beijing during the epidemic prevention and control period, and give full play to the role of the "moat around Beijing" in epidemic prevention and control.
On March 5th, the Office of the Leading Group for Epidemic Prevention and Control in Taiyuan issued seven measures to strictly manage the epidemic in Beijing. Among them, all organs, organizations, enterprises and institutions are responsible for the prevention and control of the epidemic in their own units, and in principle, their staff members are not allowed to enter Beijing during the epidemic; Railway stations, airports, bus stations and other transportation stations should strictly control the ticket purchase and quarantine check-up points, and those who find confirmed cases, suspected cases, asymptomatic infected persons, close contacts and respiratory symptoms such as fever and cough in COVID-19 are not allowed to enter Beijing; All kinds of medical institutions at all levels should strictly implement the graded diagnosis and treatment system, strictly manage the examination and approval of referral to Beijing, and in principle, they should not go through the referral procedures in Beijing for diseases that have the ability to diagnose and treat in the province.
On March 3, the Office of the Leading Group for Epidemic Prevention and Control in Cixian County, Handan City, Hebei Province issued a notice on strengthening the management of entering Beijing, stipulating that all townships and counties should fully implement the responsibility of "preventing exports", do a good job in health screening and management of people entering Beijing, and educate and guide the masses not to enter Beijing as much as possible during the epidemic prevention and control period; Those who are found to be prepared to enter Beijing will be discouraged according to the law and regulations, and those who are at risk will be resolutely prevented from entering Beijing.

Internet insurance, don’t play "risky tricks" (hot focus, rejecting financial risks around you ③)

  Cartography: Shen Yiling

  Internet insurance, playing a little "hi", beware of the false innovation of "selling dog meat by hanging sheep’s head"

  Not long ago, the stars Lu Han and Guan Xiaotong announced the news of their love affair, and the fans were boiling. Taobao merchants immediately began to sell "Lu Han Love Insurance", with a premium of 11.11 yuan per order. They promised that if Lu Han and Guan Xiaotong remained in a relationship one year later, the merchants would pay double the amount, and many fans actually took out insurance.

  Nowadays, the online world is all-encompassing, and "wonderful" types of insurance emerge one after another: illegal sticker insurance, Xiong Haizi disaster insurance, helping the elderly to be wrongly insured, forgetting to wear long trousers insurance, beauty chef care insurance, gastrointestinal insurance and acne insurance … … There are so many kinds of insurance, only unexpected, nothing impossible.

  Most Internet insurance fees are not high, and the cheap ones only need 1 yuan, and "Mao Mao Rain" is thrown at will; More than a hundred yuan, it doesn’t hurt to spend it. In addition, many types of insurance provide customized "packages", and WeChat and Alipay can transfer money. As a result, "my insurance is my master", which is personalized and disintermediated, makes it popular among more and more consumers, especially young people. According to statistics, more than 70% users of Internet insurance are young people from the post-80s to the post-90s.

  However, for consumers, some internet insurance is actually not insurance!

  First, there are suspicions of fraud and illegal fund-raising. Some types of insurance are not developed and sold by insurance institutions, and the policy has no legal effect. For example, the love insurance sold by a Taobao shop, "99 yuan, married after two years, presented wedding planning and a gift of 199 yuan; After three years of marriage, the amount of gift money has increased to 299 yuan. "It looks sweet, but in fact it hides risks — — The so-called insurance policy is just a piece of paper printed by the merchants themselves. If the merchants run away with the money after the insurance is sold, where can there be a gift to chase?

  Zhu Minglai, a professor at the School of Finance of Nankai University, pointed out that at present, some traffic platforms illegally raise funds in the name of insurance, or scatter "bait" with high returns, or forge insurance policies to defraud consumers of funds. These platforms are not qualified as insurance agents. According to regulations, they can only provide customers’ recommendation, insurance price comparison and other services for both parties, but they are obviously selling illegally.

  Second, there is a gambling nature, and "online insurance" may be online gambling. In the first two years, some regular insurance institutions sold smog insurance, World Cup regret insurance, pet pregnancy insurance, stock limit insurance and Mid-Autumn Festival moon viewing insurance. Experts pointed out that these insurance "targets" have no rules to follow, and the pricing and terms are not supported by risk data, which is no different from gambling. Fortunately, these "innovations" were all red cards in time by the regulatory authorities.

  Third, the merchants are vague about the key information, and the product name is not true. Some Internet insurance clauses are unclear, the relevant information disclosure of insurance institutions is incomplete and inadequate, or the wealth management benefits are exaggerated, the nature of insurance products is weakened, or risk warnings are lacking. The exemption and compensation exemption clauses are ambiguous and misleading, which harms consumers’ rights and interests.

  Seimi Zhang, a salesman of a private enterprise in Beijing, wants to insure a health insurance for his children. There is an insurance project on the Internet that 400 yuan can enjoy 300,000 yuan of general illness insurance coverage for an annual premium. He read the terms and conditions briefly and then took out the insurance. This year, his child was seriously ill, and the treatment and operation cost more than 100,000 yuan. When Seimi Zhang went to claim compensation, he discovered that he was insured with supplementary insurance for medical expenses. "Medical insurance reimbursed nearly 80% of the expenses, and I had to pay 24,000 yuan myself. According to the terms, the insurance company will also be exempted from paying 10,000 yuan, and finally only pay me 10,000 yuan. " Looking back at the terms, I found the existing explanations such as exemption and deductible, but they were all marked with relatively small font size. "The feeling is intentional, which makes people ignore these special explanations."

  The fourth is the risk of loss or disclosure of personal information. The relevant person in charge of Taiping Life told the reporter that some companies are currently doing business with unqualified third-party network platforms. "It seems that the platform is docked with the insurance institution’s system. In fact, after insurance, insurance institutions still have to manually export insurance information, and then complete insurance through their own online sales, electronic sales or salesman direct sales. This online and offline disjointed operation mode cannot completely retain the insurance trajectory of consumers, and it is prone to misleading sales and difficult claims. " Insiders are worried that if some insurance companies put their customers’ private data on public "cloud" servers, or their own information systems are improperly maintained, it will lead to the disclosure of customers’ personal information.

  Experts pointed out that at present, Internet insurance has just started and the market development is still not perfect. The "cheap conditions" such as network scene customization, small premium and technology application are double-edged swords for consumers. On the one hand, return insurance, mobile phone broken screen insurance and other insurance products with scientific pricing based on insurance principles have emerged, meeting the needs of multi-level and diversified risk protection. On the other hand, some "insurance innovations" that sell dog meat by hanging sheep’s heads take advantage of the network to fool and deceive consumers. Although the amount of each order is very low, it is not "high risk", but it is like "psoriasis" in the financial market, which makes people feel uncomfortable.

  Not only are consumers easily fooled, but the risks faced by the insurance industry cannot be ignored.

  The data shows that in 2012— In 2016, China’s Internet premium income increased from 10.6 billion yuan to 229.9 billion yuan, an increase of more than 20 times; The number of insurance institutions operating Internet insurance business has grown from 28 to 124. Traditional insurance companies mostly carry out internet insurance business through self-built websites or cooperation with third-party platforms. The "insurance boom" of the network platform is unstoppable, and the mobile phone insurance APP software is even more dazzling.

  But the risks are also lurking.

  The most prominent problem is that the cooperation platform party does not have the qualification, which "causes trouble" to the insurance company. The relevant person in charge of Taiping Life Insurance pointed out that once there are systemic risk events such as collective default or run on these platforms, they will be transmitted back to insurance companies, which will have a serious impact on the operating performance and solvency of insurance companies in that year or even in the next few years. "Some insurance companies carry out credit guarantee insurance business with cooperative platforms, but the underwriting assets are more complicated and the risk exposure is too large." The person in charge said.

  Secondly, fake insurance policies are repeatedly banned. The China Insurance Regulatory Commission (CIRC) recently reported a number of cases in which Internet small loan companies were suspected of fraudulently using the name of insurance companies and tying forged "accident liability insurance for small loans" policies to defraud victims of funds. Among them, Shanghai Tengwei Investment Management Co., Ltd., an institution involved in the case, has investors all over Guangdong, Jiangsu, Hebei and other provinces and cities, and the investment amount ranges from several thousand yuan to more than 100,000 yuan. The institution claims that its loan products are guaranteed by "Pacific Factoring Agency" and has also issued a "online payment account security liability insurance" policy to customers, but Pacific Property Insurance has never cooperated with this institution. Others make fakes and insurance companies lie down, and they have to bear the reputation risk of "damage is easy to repair".

  There is also data pricing risk. The person in charge of Ping An’s "One Account Connect" believes that due to the lack of relevant historical data accumulation and application, Internet insurance may have a big deviation in the operation of innovative business. "The virtuality of the Internet itself will also produce various ‘ Pseudo data ’ , affecting accurate pricing. "

  Information and technology security risks can not be ignored, including legal risks such as customer information leakage caused by improper online operation of employees, reputation risk caused by insufficient offline service ability, and sickness insurance caused by non-face-to-face transactions.

  "In the Internet age, insurance operations can break through geographical restrictions and break down industry barriers. Once risks occur, they will spread quickly." Zhu Minglai believes that insurance products are naturally social and public welfare, especially internet insurance, which covers a wide range, with more than one billion new policies each year and a huge customer base. The negative impact caused by group surrender and claims disputes will not be limited to the economic field, but will also extend to the social field. "In addition, if Internet insurance always gives consumers the impression of ‘ Bo eyeball ’ ‘ Not reliable ’ That is undoubtedly destroying the development ecology of the industry and shaking the foundation of the development of the industry. This is the biggest risk of the industry. " Zhu Ming said.

  Strengthen corporate responsibility, improve collaborative supervision, keep an eye on the "blacklist" and make good use of "big data"

  "The insurance products in the Internet and mobile apps are very strange. How do I know who is real and who is fake? Taobao shop sells insurance. Is this under the control of CIRC or the Industrial and Commercial Bureau? If it is illegal, should the platform take responsibility? " Ms. Xu, an employee of a bank in Beijing, believes that Internet insurance is developing by leaps and bounds, and supervision should be strengthened.

  On October 13th, 2016, the China Insurance Regulatory Commission issued the Implementation Plan for Special Remediation of Internet Insurance Risks, which warned against misleading behaviors such as misrepresentation, one-sided or exaggerated publicity of past performance, illegal promise of income, cooperation between insurance companies and third-party network platforms without business qualifications, and illegal Internet insurance business by non-licensed institutions.

  "According to the existing regulatory framework, only licensed institutions can sell insurance, and only those that meet the core requirements such as actuarial laws ‘ Insurance ’ It can be called insurance, but the situation in the market is still quite serious. " Insiders pointed out that the Internet has a wide range of layers, and it is not possible to rely solely on a certain regulatory department to purify the Internet insurance market. It requires the coordinated governance of financial, industrial and commercial, information and other management departments.

  As far as the insurance industry itself is concerned, the insiders believe that the following aspects can be "done right away":

  "In terms of product development, no matter what the third-party platform proposes ‘ Brain hole ’ Insurance companies should follow the product development process and strictly control insurance risks; In terms of operation, establish an effective internal control system, strengthen the management of sales behavior, and ensure that the business is flawless and there are no major business risk events and reputation risk events. " Zhu Ming said.

  The relevant person in charge of Taiping Life Insurance said that insurance institutions should resolutely stop cooperation with third-party platforms that do not have business qualifications and online lending platforms that provide credit enhancement services, set up fund pools and illegally raise funds. At the same time, consumers should be reminded to regularly check the product contents in industry associations or insurance companies in official website and obtain product information from formal channels.

  "For underwriting risks, operational risks, information security risks, etc., we should improve the technical level and establish network security ‘ Moat ’ 。” Qiu Hui, deputy general manager of Ping An Health Insurance Technology Center, said, for example, intelligent analysis based on big data is carried out for product pricing, and accurate pricing is carried out according to multi-dimensional data such as history, region, market and reinsurance to ensure controllable risks; For operational risks, insurance companies should conduct strict process and authorization control through various authorization, upgrade and encryption systems to ensure that limited and authorized internal personnel can carry out specific operations; For external information access, sensitive data is limited to the customer by applying various intrusion detection, firewall, encryption and other technical means, and strict access control is carried out before, during and after the event to ensure information security.

  Not long ago, SF Express made the sender and receiver "see the code but not the name" by scanning the code to prevent the customer information on the face sheet from being leaked. Insiders suggest that insurance companies should also form a closed-loop transaction with the help of third-party platforms, and customer information input, transfer payment, etc. are invisible to third parties.

  How should the regulatory authorities plan ahead?

  "The premise is to encourage innovation and reserve space for the healthy development of Internet insurance with an open and inclusive attitude. At the same time, effectively protect the rights and interests of consumers, focus on strengthening supervision in product development, information disclosure, information security, landing services and third-party platforms, and enhance the transparency of Internet insurance business. " Zhu Ming said.

  Taiping Life suggested that regulators should strengthen the management and sharing of information on responsible subjects related to illegal and untrustworthy behaviors in the insurance field, and form a regular notification and publication mechanism, such as the blacklist of third-party online platforms for Internet insurance, so as to further strengthen the risk prevention and control of the insurance industry and effectively isolate the transmission of other risks.

  In addition, the current industry data is scattered, which is divided into insurance companies, industry platforms, front-end customer APP import data, mid-end intermediaries, channels, claims, call data, back-end financial receipt and payment data, and so on, and there are many kinds and complexities. The insiders suggest that a big data platform should be established as soon as possible, the standards for data storage and transmission should be unified, and data from different systems should be opened, and then data mining should be carried out according to different needs, so as to strengthen the application of big data in anti-claims fraud and optimize products and services for the industry. Provide basic services.

See also the "business story" of the star street brand "overturning" and "cutting leeks" is not so good to sing.

  A few days ago, the Shanghai Municipal Market Supervision Bureau notified two batches of unqualified down jacket products, among which a certain type of "DANGEROUS PEOPLE" brand short down sold by Shanghai Yanxun Trading Co., Ltd. was unqualified, with alkyl phenol (AP) and alkyl phenol polyoxyethylene ether (APEO). These two components are environmental hormones, which can easily affect the normal hormone secretion of human body. It is reported that "DANGEROUS PEOPLE" is a menswear brand launched by artist Joker Xue. This bulletin has caused a wide discussion. As of 14: 00 on January 5th, the reading volume of related Weibo topics has exceeded 120 million.

  In fact, the "rollover" of star street brands is nothing new. Previously, a blogger sent a video saying that he spent 1,500 yuan to start the fashion brand UGC coat created by artist Lu Han. I didn’t expect poor workmanship and many threads, "the cost does not exceed 60 yuan"; Nana Ou-yang, who has tens of millions of fans, launched his own brand "nabi", which was also pushed to the forefront of public opinion because the pajamas with a price of 988 yuan were actually made of ordinary materials; The flagship store of MADNESS Tmall, a trendy brand founded by actor Shawn Yue, terminated its operation on its own in January 2023. From the consumer evaluation, poor quality and high price are the biggest problems of its closure … At present, more than 2.5 million related web pages can be found by searching on Baidu platform with "star fashion brand overturned" as the key.

  The reason why star street brands are sought after and have a market is largely due to the halo effect of stars. If we look at the value of the products alone, we may not be able to afford such a high premium. Relying on the star filter can certainly attract a wave of fans to pay the bill, but the product is a commodity after all, and it has to return to the basic law of value. Excellent quality and novel design can give all consumers, including fans, the motivation to continue to buy, and pursue long-term doctrine to maintain a good reputation. If you just want to "harvest for a while" to make quick money, this "business" may not be so good to sing. (Reporter Zhan Jiaomei)

Analysis after the game: Li Kaier remained on the sidelines for a long time, and the China men’s basketball team beat Cape Verde in Africa.

Last night, at the Italian Trentino four-nation invitational tournament, China narrowly defeated Cape Verde, a small African country. Surprise means that when the first quarter of the game started, China was 4-14 behind, with a maximum score difference of 10 points; No danger, it represents the result of the game. China beat Cape Verde by 20 points.

The most anticipated "sledgehammer" Li Kaier’s national team debut was not staged as scheduled. It seems that the secret weapon of the China men’s basketball team will not be easily taken out. That’s all right, although the fans are a little disappointed, our World Cup opponents can’t study you thoroughly, and it’s not good to formulate corresponding tactics in advance. One day later, the risk will come one day later, not to mention that African teams are not strong teams in the traditional sense.

In fact, from the absence of warm-up before the game, it can be confirmed that Likel will not play. Sure enough, as soon as the game whistle sounded, Li Kaier sat firmly in the coach’s seat and just watched.

The problem of slow heat in China men’s basketball match really made people break out in a cold sweat. Especially Zhao Rui, the starting defender of China team, played too rough. I can’t break through with the ball, and then I make a foul after the mistake. The old habit of being hot-headed is worrying. On the other hand, the players in Cape Verde are really in excellent physical condition. Apart from their height and arm length, they are also enviable in jumping, and when they rise, they still have three long-range shots. Three times five divided by two, ten points ahead at once!

Fortunately, the China team was not intimidated by the African’s three axes. With Cui Yongxi scoring a 3-pointer, the game gradually entered the rhythm of the China men’s basketball team. Once the rhythm is right, the skills and tactics will be brought into play. Suddenly, it was discovered that under Qiao Shuai’s training, the China men’s basketball team was thoroughly remoulded and transformed into a world-class team.

Hands-free dunk, key whistle for three points, pull-rod layup under the basket … The ball is moving, and there is no waiting for the ball. Everyone is running, and there is always an ambush outside the three-point line. The European team’s basketball style is placed on China players, and its power is so terrible. I have to say, Qiao Shuai deserves to be a world famous handsome, or there is something really.

Of course, there will always be more gaps and opportunities to play against African teams. Because African teams are characterized by strong personal ability, but weak teamwork, to put it bluntly, they are fighting on their own. Through this game, we can also detect some problems existing in the three lines of this China team.

The defensive line is still the most problematic position. Although Zhao Jiwei and Zhao Rui, the "Second Zhao", have outstanding advantages, they are still stubborn. Zhao Jiwei scored 4 points and 9 assists, and his organization was excellent in series, but he didn’t score many points. Zhao Rui scored only 4 points on 2 of 9 shots. Although he was physically antagonistic, he was prone to fever and his state fluctuated greatly.

The most admirable thing is China’s three inside towers: qi zhou, Wang Zhelin and Hu Jinqiu, who have made great contributions to the team as a whole. Needless to say, qi zhou, sit tight. After playing for 18 minutes, he scored 8 points and 3 rebounds on 4-for-5 shooting, and his strong play at the basket and follow-up dunks fully reflected qi zhou’s dominance in the field.

Wang Zhelin can be called a kaleidoscope on the offensive end. There are many moves, whether it’s a face box or a back play, it’s extremely tough and reassuring. The only shortcoming is that the shooting percentage of free throws after repeated fouls by the other side is too low, and only 3 of 7 free throws are made, so you should practice hard on free throws.

Hu Jinqiu’s basic skills are solid, and he has a strong grasp ability. Basically, he can score as long as he has an opportunity. He scored 8 points and 3 rebounds in just 13 minutes. He made 3 of 3 shots and 2 of 2 3-pointers.

The performances of Zhang Zhenlin and Cui Yongxi in the forward position are also amazing, especially Cui Yongxi, who scored 8 goals in 9 shots, and his lethality can be described as a knife, winning the team’s highest 18 points and 4 rebounds.

In this way, it is really unnecessary to take out China’s secret trump card weapon "sledgehammer". In the next match against Italy, I believe Qiao Shuai will take out his hidden "Italian cannon".
