Chapter 708 Lime topological superconducting vortex theoretical model system

Quantum computer is not a term of black technology, but it is indeed one of the most popular and cutting-edge technological directions in the world today. Its powerful parallel computing capabilities far exceed the current conventional computers and even supercomputing. This advantage is in encryption and deciphering. areas are particularly evident.Moreover, quantum computers have the ability to simulate any natural system in theory, which is the key to the development of artificial intelligence.

These advantages have attracted countless quantum physicists to devote themselves to research, only to make real quantum computers put into practical applications as soon as possible.

Quantum computer research on a global scale has also entered a white-hot stage, and various countries are stepping up research and development in order to gain a leading edge in this field.At present, quantum computers have been successfully built in many countries. Countries such as De, Eagle, Japan, America, and Xia are all at the forefront of the world in terms of quantum computers.

For example, the Jülich Research Center in Germany has a quantum computer with 5000 qubits; IBM and Google have quantum computers that have set world records; Finland and the European quantum computing company IQM have developed a new super quantum computer that can realize quantum logic gates. The commercial quantum computer "Unicorn" with qubits; Japan's domestically produced quantum computer has been officially put into use a few days ago; Xiaguo's Baidu officially released its first industrial-grade superconducting quantum computer "Qianshi". The quantum computer chip "Wukong" using domestic quantum cores will also come out soon.

However, these quantum computers are still at a relatively early stage. Except for Germany, which has the first commercial quantum computer with 5000 qubits in Europe, the most powerful quantum computers of other countries and companies, including IBM, are only at 433 qubits. At the level of qubits, quantum computers in most countries only have 64 qubits.

The development of quantum computers is severely limited, and the key is that the problem of "quantum decoherence" cannot be solved.

The so-called "quantum decoherence" means that the qubits are affected by the external environment to produce quantum entanglement, which reduces the quantum coherence due to interference and produces a "decoherence effect", which will greatly increase the error rate of quantum computing.The higher the number of qubits, the more exaggerated this error rate becomes.The current international mainstream error correction mechanism to solve the "quantum decoherence" phenomenon can only ensure the normal operation of quantum computers with 64 qubits.

Topological quantum computing is a very important topic. It can use the topological quantum states in many-body systems to store and manipulate quantum information and achieve high fault tolerance in quantum computing.

It can be said that whoever masters the core technology of topological quantum computing holds the key to the future development of quantum computers.

Therefore, among the current quantum physicists, the number of people devoted to the subdivision of topological quantum computing is the largest, and the technical routes produced are rich and diverse. In the direction of superconducting quantum, there are ultra-cold atom quantum simulation and ion system quantum computing. , Silicon-based quantum dot quantum computing, topological superconductor quantum computing, topological insulator quantum computing and other different research directions, the competition is extremely fierce.

At around 12:22 on December 23, Lime Technology Quantum Computing Laboratory on the outskirts of Beijing finally took the lead in realizing topological quantum computing in the direction of superconducting quantum, and it is a relatively mature topology that can support million-level quantum computing. The theoretical model system of quantum computing.

This achievement is of great significance and amazing. Not to mention anything else, the research results in it alone can write more than a dozen papers published in "Nature" and "Science".

After the excitement of the crowd subsided, they booed and asked Qin Ke to give this topological quantum computing theoretical model system a name. This naming right was not because Qin Ke was the boss of the crowd, but because Qin Ke was the most important player in the entire project research. The key role, the person who plays the biggest role, especially in the details of quantum mechanics, Qin Ke's strength is enough to make all the scientific researchers regard him as a god.

Qin Ke didn't give in either, he thought for a while, and said with a smile: "Our research direction is the 'topological superconducting vortex state', so let's put it simply, it's called the 'lime topological superconducting vortex state theoretical model system'." When the paper is published, everyone here is doing two and three works!"

The crowd broke out into excited cheers again!

Such a great paper that is destined to shock the whole world and greatly affect the development of quantum computers, even if it is just to leave a name in the "Acknowledgments" above, it will be worth bragging for a lifetime, let alone being listed in the author column .

What's more, everyone knows that this "lime topological superconducting vortex state theoretical model system" is sorted according to the degree of contribution. The first must be Qin Ke and Ning Qingyun, as well as Professor Kopet who has done a lot of work in the early stage. , and then there are Harold and other nationalities who have been involved in this research from the beginning, as well as Ling Shaotang and Gan Peixuan who played an important role in the experiment, and the rest of the researchers who joined after the establishment of the Quantum Computing Laboratory, even It's three works, all of which are enough to be overjoyed.

——According to domestic practice, experimenters like them often have no chance to appear in the author column.

It was already 23:10 in the middle of the night, and the north wind was howling outside, but everyone was excited and didn't feel sleepy, so Qin Ke took everyone to the lounge of the laboratory to drink and celebrate.

In consideration of the living habits of scientific researchers of German nationality and in order to create a better and more relaxed scientific research environment, the Quantum Computing Laboratory has specially added a lounge with a bar, which is filled with various drinks and imported from Germany. There is no shortage of German beer, red wine, and snacks. There are even two large TVs connected to XBOX and PS3 game consoles for everyone to relax and entertain.

However, in the past four months, most people have devoted themselves to research and experiments. At most, they come here occasionally to drink and brag, or to eat instant noodles and snacks here when they are too hungry at night. No one touched it at all.

In fact, Lime Technology specially arranged a dormitory for a group of researchers in a nearby community, and it took less than 10 minutes to walk. However, Harold and other researchers who came from abroad really worked hard, and many of them only went back once a week. The rest of the time they spend in the lab, don’t even take a shower, eat lunch when they’re hungry, and sleep in a nest when they’re sleepy—then the lab had to prepare a batch of simple lunch break beds for this group of addicted to research Unable to extricate themselves from sleep.

After a long time, the researchers of Xia Guo nationality were aroused to be competitive, and they thought to themselves that compared to "jumping", can't we still win the countrymen?
As a result, Lime Quantum Lab had to add a new batch of lunch break beds, and changed several vacant rooms originally intended to be used as activity rooms into temporary dormitories, and added several bathrooms.

For this reason, Zhou Shutao, the CEO of Qingning Technology, also called Qin Ke to "complain" and joked that the dormitories in the community were all rented for nothing, and the rent was wasted in the past few months.

It can be said that the rapid progress of the topic of topological quantum computing is the result of everyone's concerted efforts and sincere cooperation.

In the lounge, Ning Qingyun went to chat with another girl, Gan Peixuan. The two girls were not convenient to drink, so they just drank a drink. Qin Ke opened a can of German dark beer, respected everyone, and then sat down. next to Rhodes.

There were already three empty cans of dark beer next to Harold. This guy drank fiercely. His face was flushed and he smelled of alcohol. He clinked a glass with Qin Ke vigorously and said in German: " Professor Qin, once again I am glad that I chose to come to Xiaguo. You are a good boss and a good guide! Professor Coppett will be crazy when he hears that we have completed this project. Last time he heard We have researched 'the most ideal Majorana fermion carrier', and we were so excited that we didn't fall asleep all night, saying 'Professor Qin is really amazing'..."

Qin Ke smiled, clinked glasses with him and took a sip of beer: "Professor Koppett's cell phone doesn't seem to be with him. I wanted to make a video call with him just now, but he never accepted. Later, I sent him an email, hoping he would Can see this good news as soon as possible.”

Harold looked gloomy: "Professor Koppett has been busy with rehabilitation recently, but according to his family doctor, the most optimistic estimate is that he can move around in an electric wheelchair, and his fingers can't hold a pen for a long time. ..."

Harold is a very affectionate person. Although he was in Xiaguo for the past four months, he took time every week to contact his teacher, Professor Kopet, who was in Deguo for treatment.

Qin Ke patted him on the shoulder: "I don't think he should worry about the next living expenses and medical expenses. Our topological quantum computing project is more inclined to theoretical research, but it will also produce related patented technologies. Then I will According to the agreement, Professor Coppett will be listed as the patentee and enjoy one-third of the patent licensing income. Of course, before the patent generates income, Professor Ning and I will transfer 200 million euros to him in advance to ensure that he Living and medical expenses for the next ten years."

Topological quantum computing will have at least two patented technologies.The first item is naturally "the most ideal Majorana fermion carrier", which is now named "Majorana fermion carrier-Lime superconducting No. [-] material" synthesis technology.

The "Topological Gap Theory System" that was successfully verified tonight can also produce a patent for "a technology that uses the Topological Gap Theory System to realize the precise regulation of Majorana zero-energy mode weaving operations".

These two patents are the key to transform the theory of "lime topological superconducting vortex state theoretical model system" into practical application. As long as the declaration and filing of patent rights are completed in Xiaguo and major countries in the world, anyone who wants to adopt This highly fault-tolerant technology of topological quantum computing must apply for patent authorization. It is conservatively estimated that the value of these two patents is more than 10 billion US dollars.

Surprised and delighted, Harold stood up abruptly, not daring to answer: "Really?"

Professor Koppett is a professor at the University of Munich. He belongs to the high-income group, with an annual salary of around 20 euros (about 150 million yuan). The medical benefits are quite good, and basically the treatment expenses can be reimbursed. It stands to reason that Professor Coppett should not worry about money.

But in fact, Professor Coppett’s family is not well-off. He has five children, and they are not very up-to-date. He is in his 30s, and he often asks Professor Coppett for money. Even the house and car are Coppett’s. Professor Te solved it for them.Professor Coppett's wife has also been out of work and is a full-time housewife. In addition, Germans do not have the habit of saving. Now that Professor Coppett's income has been halved due to illness, he is tense.

The most important thing is that although Professor Copette does not need to spend much money on medication and rehabilitation, he is very inconvenient to move around now. His wife is not in good health and cannot take good care of him. He can only hire professional nurses to take care of his daily life. It is this additional expenditure, which will increase the cost of about 4 euros per year.

Harold has a deep understanding of the situation of his mentor's family, and secretly thought of helping him out. Now he heard that Qin Ke was willing to share the income from patent licensing according to the original agreement, and he was so careful to support the income of 200 million euros in advance. Sharing—this is equivalent to giving Professor Coppett his original ten-year salary in advance, which is enough to ensure that his life in the next ten years will not be affected.

Seeing that Qin Ke nodded affirmatively, Harold held Qin Ke's hand vigorously, moved his lips and wanted to say something, but he didn't say anything after all. He bowed slightly to Qin Ke, then got up and went to explain Qin Ke's decision. Tell the rest of the partners from Germany.

A group of scientific researchers from Deguo looked at me, and suddenly someone came to Qin Ke and said seriously: "Professor Qin, I am willing to stay in Xiaguo to work for you."

"I would too."

"We are all willing!"

In the end, [-] scientific researchers with nationalities who originally signed only one work contract, and Harold, who originally signed a five-year work contract, were willing to change to a ten-year work contract.

The reason for signing the ten-year contract is because the international labor contract between Germany and Xia Guo can only be signed for a maximum of ten years.

For Harold and others, such a decision was made after serious consideration. There is a high-level academic leader as the boss, and the salary is good. These are enough to make them follow with all their heart.

Looking at Qin Ke surrounded by scientific researchers of different nationalities, Gan Peixuan couldn't understand German and didn't understand what happened. She understood after listening to Ning Qingyun's translation.She opened her eyes wide in surprise, then held up a drink to touch Ning Qingyun, and said with a smile: "Professor Ning, Man Ting and I also plan to work hard for you and Professor Qin for the rest of our lives, please take care of us."

Ning Qingyun pursed her lips and smiled softly, her gaze on Qin Ke was gentle and proud.

"my pleasure."

……

In the end, the celebratory dinner lasted until about 1:[-] in the morning. The laboratory was simply cleaned up, and all research materials were locked in the safe, and everyone dispersed separately.

All the scientific researchers returned to the dormitory to rest, and the Lime Quantum Laboratory ushered in the long-lost silence, but the security guards in charge of security work collectively stepped up their vigilance to prevent any accidents from happening.

Because it was too late, Qin Ke didn't ask his assistant Fang Yongtang to pick them up. He drove the car by himself and took Ning Qingyun back to the school villa to rest.

Along the way, I saw snow everywhere outside, but fortunately, the wind and snow during the day had stopped.

Ning Qingjun was physically weak. After returning home, she took a shower and dried her hair, and soon fell asleep under Qin Ke's "urging".

Qin Ke was in good spirits. He got up quietly and checked it with his mobile phone. The weather forecast showed that it would be sunny in the next two days.

With luck, it looks like a backup plan won't be necessary.

In order to complete the grand proposal ceremony on December 12th, Qin Ke designed several plans for various possible weather conditions.

Now that the weather is fine, the best solution can naturally be adopted.

Qin Ke used his mobile phone to send a message to several numbers: "Everything is going according to plan." Then he returned to the bed and kissed Ning Qingyun's innocent and lovely face after sleeping.

Good night, my dear Xiaobaicai, I hope the next surprise will make you unforgettable forever.
