I really just want to be a scholar

Chapter 584 New Directions for Topological Quantum Computing
The call came from Professor Coppet who was far away in Germany.

Normally, Professor Copette communicated with them mainly through emails, and it was rare to make direct international phone calls, so both Qin Ke and Ning Qingyun were greatly surprised.

Qin Ke connected the phone, and Professor Copette's voice of annoyance and indignation came from the phone: "Dr. Qin Ke, first of all, congratulations on solving another world-class mathematical problem. Excuse me during champagne, but now our cooperation project topological quantum computing has encountered a big problem. Last time you and Dr. Ning Qingyun discovered the Andreev bound state discrimination problem, and the data anomalies in tunneling electron excited plasma The problem, yes, is that we were all played by that guy, Pullan Wheeler!"

Professor Coppert is indeed in big trouble.

Topological quantum computing is a very popular cutting-edge theoretical field in quantum computing. Once it is solved, it can greatly improve the fault tolerance rate of quantum computing, making quantum computing move from the laboratory to industrial applications. Just a rough estimate, the market size exceeds One trillion.

Such a topic with bright prospects and a broad market is of course not the only researcher of Professor Coppert’s team. Many physics research institutions around the world, famous professors of condensed matter physics, and even laboratories of large companies have invested a lot of money, time and energy in Inside, in order to strive to be the first to pick this sweet fruit that can bring great fame and fortune.

The competition is so fierce, and the benefits are so huge, it is natural that some people will use some dishonorable means to attack their opponents or gain an advantage.

Unfortunately, Professor Coppert's team encountered such a conspiracy.

The clue of the matter was that one of Professor Coppett's doctoral students, Puran Wheeler, dropped out of school suddenly and disappeared.

This Pullan Wheeler is one of Professor Coppert's proud disciples. He participated in this topological quantum computing project almost all the way, and also helped with the sorting and analysis of many important data.

When Puran Wheeler just disappeared, Professor Coppert was still worried about his students, so he hurriedly reported to the school, and even called the home of Puran Wheeler’s parents to inquire about the situation, but found that Puran Wheeler did not go home, but just gave The poor family transferred a large amount of money, and then excused that they were going to travel abroad, but there was no news.

Professor Coppett finally found something was wrong, especially after checking the surveillance video, he found that before dropping out of school and disappearing, Polan Wheeler used a USB flash drive in violation of the regulations and copied a lot of data from the computer of the research group!Professor Coppett hurriedly reported to the school, and the school contacted the police, and finally found that Puran Wheeler had already left Germany and flew to the United States.

There are various indications that Purlan Wheeler was bought with a lot of money and handed over the important materials and data in the team to another scientific research institution in the United States.

This is not the worst. The worst thing is that Pullan Wheeler should have been bought long ago. In the past two months, he has continuously tampered with the experimental data in the research group, making the original data handed over to Qin Ke and Ning Qingyun It has many mistakes.

Quantum computing is originally a very microscopic subject, and a little difference in data can lead to thousands of miles of error. At the beginning, Qin Ke and Ning Qingyun hadn't discovered it. Professor Te sent the data again. When the two were optimizing the mathematical model, they found that the deviation of the data for identifying the Andreev bound state was particularly large, and the number of plasmas excited by the tunneling electrons in the dissipative resistance was different from the previous mathematical model. The deduced results are quite different.

Therefore, after repeated deduction and calculation, Qin Ke carefully wrote an email to Professor Kopet, asking him to re-check the theoretical research and experimental data of last month, and do not proceed to the next step until then. researched.

Professor Copette didn't think so. He was very confident in his team, but after carefully reading Qin Ke's email and the accompanying deduction calculation results and theoretical basis, his confidence was shaken, so he announced to the team to restart the previous project. Months of work looking for what might have gone wrong.

Probably because of this action, the ghostly Polan Wheeler panicked. He was afraid of being exposed and sent to prison, so he quickly copied the data and fled...

"The school has submitted an application to the National Academy of Sciences to hunt down Polan Wheeler, and the National Academy of Sciences will come forward later to let the International Society for Theoretical Physics put pressure on the American Institute of Physics to force the other party to find and hand over Polan Wheeler, but in any case , we have suffered a big somersault this time."

After explaining the situation angrily, Professor Coppett said bitterly: "Because of that damned Puran Wheeler, our progress in the past three months has been cleared, and the worst thing is that our research results have been leaked. It is very likely that competitors will greatly improve their research progress, and our originally insignificant advantages have disappeared."

Qin Ke comforted: "Professor Koppett, the situation is not too bad. Even if the other party has obtained the information, it is only useful based on our previous mathematical model deduction and the data verified by your team. The most critical mathematical model is still there. In the hands of Qingyun and I, without our mathematical model, it will be difficult for them to make new breakthroughs."

He pondered for a while, and proposed: "Professor Koppett, after these four or five months of joint research, I think that although the research direction of superconducting/semiconductor nanowires you originally studied is the mainstream in the world today, but because It is the mainstream and relatively mature, which makes the competition extremely fierce, and it is difficult to have particularly eye-catching results that surpass others. It is more likely to have incidents like this one, making the research results a stepping stone for others. I suggest, Do you want to try another direction?"

"A new direction?" Professor Coppet frowned: "Do you mean topological superconducting vortex state, single layer/interface and heterojunction topological superconductivity, or topological quantum computing based on two-dimensional electron gas?"

These three are new research directions in the field of topological quantum computing that have only been proposed in the last ten years. At present, no national scientific research institutions have achieved great results, but there is no doubt that these three new directions are extremely vital. Just because the foundation is weak, it will be difficult to turn to these three new directions.

Qin Ke nodded and said: "Yes. I think the topological superconducting vortex state is a relatively good choice. I know that you also have another team conducting research on topological insulators. It is not too difficult to prepare artificial topological superconductor materials from this topological insulator. High, and cutting into quantum computing from this direction can reduce a lot of workload. The most important thing is that this direction is most suitable for the use of mathematical modeling, and it can give full play to the advantages of me and Qingyun."

The biggest problem with quantum computing is that it is disturbed by the environment, making the quantum state unstable and causing unpredictable errors in calculations. Topological qubits composed of "Majorana zero-energy modes" can solve this problem in principle, and there is a Majorana zero-energy mode on the surface of the center of the topological superconducting vortex, which is also the "topological superconducting vortex state." "Theoretical basis.

Professor Copette pondered: "This proposal is very attractive, but it has a lot to do with it. I need to call everyone in the research team, including you and Dr. Ning Qingjun, to discuss it together. In this way, we will spend three days to discuss it. Discuss the feasibility, and three days later, we will have a video conference to decide whether to change the research direction to the topological superconducting vortex state."

After finishing the call, Ning Qingyun asked curiously: "Qin Xiaoke, if I remember correctly, you have been letting me read the information on topological superconducting vortex states before? You have wanted to make this suggestion a long time ago?"

"That's right." Qin Ke smiled.

He made this suggestion really selfishly.

The S-level knowledge that the system rewarded him before "The whole process of making a new type of carbon crystal composite nanomaterial suitable for 1nm chips" involves the details of artificial topological superconductor materials, and the method of realizing quantum computing in it is Topological superconducting vortex states.

It's just that it's not detailed enough, and Qin Ke struggled to read it. Most of the information found on the Internet is relatively old and of little use.This is also an important reason why Qin Ke has not been able to understand this S-level knowledge for a long time.

If Professor Coppett, an academic leader in quantum theory, studies this direction of topological superconducting vortex state, it will be of great help to Qin Ke. At least the research results obtained by Professor Coppett's team will greatly improve Deepen Qin Ke's understanding of "The whole process of making a new type of carbon crystal composite nanomaterial suitable for 1nm chips", which will lay a solid foundation for him to develop a new type of carbon crystal composite nanomaterial in the future.

Qin Xiaoke, who was sitting next to him practicing painting, suddenly sighed like a grown-up: "Brother, sister Ning, I can't understand what you are saying more and more. I feel that there is a generation gap with you, and I am very depressed."

Qin Xiaoke came to the nursing home, but got along very well with Grandpa Ning Ning Jingguang and Grandma Chu Chu Mimei. After all, the little girl is innocent, lively and clever, and is very good at pleasing the elderly. She also brought a group of Qin Ke and Ning The rapeseed and tomato seeds that Qingyun researched were planted in flower pots with the two old people, which made the two old people laugh often.

Ning Qingyun hasn't seen her grandparents smiling so happily for a long time, so she is grateful to Qin Xiaoke from the bottom of her heart, and hurried over to gently stroke Qin Xiaoke's hair: "Your brother and I have just finished discussing academic matters. , how about we take you to the top of the mountain?"

The nursing home is halfway up the mountain. There are steps to the top of the mountain. The scenery there is very good, and there are various recreational facilities. It is the favorite place for the elderly in the nursing home.

Qin Xiaoke actually just wanted to act coquettishly. Seeing Ning Qingjun pampering him, he immediately narrowed his eyes, shook his head and said, "No need, Sister Ning, you and my brother can continue to do research. I don't understand, but look If you are happy, I am also happy."

Qin Ke remembered that he hadn't taken this little girl out to play much during the summer vacation, so he thought for a while and said, "I'll take you to various villages tomorrow. Real response."

This proposal also received warm responses from Qin Xiaoke and Ning Qingyun.

So in the next three days, Qin Ke personally drove to several towns with the best sales of new-type seeds more than [-] kilometers away, and found that new-type corn, rapeseed, and rice all had a large planting area. , especially rapeseed, can use natural compost to achieve green and high yield, reduce the cost of chemical fertilizers, and taste sweet and refreshing, which is very popular among farmers.

Although the yield of rice is slightly inferior to that of the mainstream hybrid rice in the market, it is superior in terms of fertility requirements, insect resistance, and herbicide resistance, making the planting profits higher at the same cost, and many farmers have begun to try to plant.

Qin Ke once asked an old farmer outside the seed shop: "Old man, why did you buy dozens of packets of corn seeds at once? This can plant at least [-] acres of land, why don't you try planting it first?"

The dark-skinned old farmer saw a boy wearing big sunglasses and a hat, and next to him was a girl who also wore sunglasses and a hat. She looked like a child in the city, and said with a smile:

"You guys from the city also care about farming? My baby recommended it. The baby said that it was researched by two of the most talented students, and these two gifted students have a special conscience. As long as you look for them You can buy the research results with confidence. I have also bought the tomatoes they researched before, and they are really easy to grow. They can grow in wasteland, and the yield in mellow soil is much higher than that of the previous ones, so this time I heard that they have. The new seeds they invented came quickly to buy.”

These words gave Qin Ke and Ning Qingyun both a sense of accomplishment and pressure, because they found that many farmers did not understand the experimental data at all, nor did they understand the brand or not, and they just looked for the " Produced according to the patents of Qin Ke and Ning Qingyun, they bought seeds with confidence and planted them.

After leaving the seed shop, Ning Qingyun sighed softly: "Although it can improve the life of the farmer's uncle, I feel that the research is very meaningful, but I also feel a sense of sincerity, fearing that I will live up to this trust."

Qin Ke rubbed his nose and said with a smile: "It's enough to turn this trust into motivation. To change the world with scientific research results and make the world a better place. Isn't that our goal?"

Qin Xiaoke continued to comfort: "Yes, sister Ning, you have done a good job. If nothing else, at least the mathematics teaching materials you compiled have helped countless students who are not good at mathematics, such as me."

On the same day, the three of them returned to the nursing home, and Qin Ke and Ning Qingyun joined Professor Copette's video conference after dinner.After collective discussions and discussions, a new consensus was finally reached, and the research direction of topological quantum computing was changed to "topological superconducting vortex state", and new research began to be carried out intensively.

This is good news for Qin Ke. In the next few days, both he and Ning Qingyun plunged into this new direction of topological quantum computing, and carried out theoretical exploration and derivation together with Professor Copette's team. and perfect.

Time came to the end of August in a blink of an eye, and Qin Ke and Ning Qingyun were about to return to the capital to start their postgraduate life in the Department of Physics.

And the IMU also sent new news, which is composed of Professor Faltings, Professor Tao, Professor Linden Strausch, Professor Wiles and other [-] highly authoritative mathematics experts in the direction of analytical number theory. The "Riemann Conjecture Five Expressions Judging Panel" has been established, and will review Qin Ke's published papers on the first four sets of expressions and the fifth set of expressions that have been submitted to the "Annual Journal of Mathematics" but not published within the next month. Expressions and their derivations are centrally reviewed.

One month later, the review team will invite Qin Ke to make a formal "defense" via video link.

The results of the review together with the results of the "defense" will become the final basis for whether IMU finally admits that Qin Ke has proved the Riemann Hypothesis.

The wonderful and tense golden autumn and September, together with the new semester and new postgraduate life, will soon begin.
