Chapter 583: New Directions in Topological Quantum Computing
The call came from Professor Coppet who was far away in Germany.
Professor Coppet usually communicated with them mainly through emails, and it was rare to make direct overseas phone calls, so both Qin Ke and Ning Qingyun were greatly surprised.
Qin Ke answered the phone, and Professor Coppet's slightly annoyed and indignant voice came from the phone: "Dr. Qin Ke, first of all, congratulations to you for solving another world-class mathematical problem. I shouldn't have to wait for you to enjoy your victory.
Excuse me during the champagne, but now our collaborative project topological quantum computing has encountered a big trouble. Last time you and Dr. Ning Qingyun discovered the Andreev bound state screening problem, as well as the data anomaly of tunneling electron-excited plasma.
The problem does exist, we were all fooled by that guy Plan Wheeler!"
Professor Coppet is indeed in big trouble.
Topological quantum computing is a very hot frontier theoretical field in quantum computing. Once solved, it can greatly improve the fault tolerance rate of quantum computing and move quantum computing from the laboratory to industrial applications. Just a rough estimate, the market size will exceed
One trillion.
Of course, Professor Kopet’s team is not the only one who is researching this topic with bright prospects and broad market. Many physics research institutions around the world, famous condensed matter physics professors and even laboratories of large companies have invested a lot of money, time and energy.
Inside, strive to be the first to pick this sweet fruit that can bring great fame and fortune.
The competition is so fierce and the interests are so huge, naturally some people will use less honorable means to attack their opponents or compete for advantages.
Unfortunately, Professor Koppet's team encountered such a conspiracy.
The clue to the matter was that one of Professor Coppett's doctoral students, Plan Wheeler, suddenly dropped out of school and disappeared.
This Pullan Wheeler is one of Professor Coppet's favorite disciples. He has participated in almost the entire process of this topological quantum computing project, and also helped with the organization and analysis of many important data.
When Pullan Wheeler first disappeared, Professor Coppert was still very worried about his students. He quickly reported it to the school and called Pullan Wheeler's parents' home to inquire about the situation. However, he found that Pullan Wheeler did not go home, but only called her.
A large amount of money was transferred to my family who was living in a tight financial situation, and then they used the excuse that they were going to travel abroad, but there was no news about it.
Professor Kopet finally realized that something was wrong. Especially after checking the surveillance video, he found that before dropping out of school and disappearing, Plan Wheeler had illegally used a USB flash drive and copied a lot of information from the computer of the research group! Professor Kopet quickly reported it to the school.
, the school contacted the police, and finally discovered that Plan Wheeler had already left Germany and flown to the United States.
There are various signs that Plan Wheeler was bought with a large sum of money and handed over important information and data from 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 bribed a long time ago. In the past two months, he has been constantly tampering with the experimental data in the research group, making the original data handed over to Qin Ke and Ning Qingyun
It has many errors in itself.
Quantum computing is originally a very microscopic subject, and a small difference in data can lead to huge differences. At the beginning, Qin Ke and Ning Qingyun didn't realize it. At the end of last month, when the two were on vacation at the beach, they happened to know each other.
Professor Te sent the data again. When the two of them were optimizing the mathematical model, they found that the data deviation for identifying Andreev bound states was particularly large, and the number of plasmas excited by tunneling electrons in the dissipation resistor was different from the previous mathematical model.
The deduced results are quite different.
Therefore, after Qin Ke conducted repeated deductions and calculations, he very carefully wrote an email to Professor Kopet, asking him to re-check last month's theoretical research and experimental data. Before that, do not proceed to the next step.
of research.
Professor Coppet was still unconvinced. He was very confident in his team. However, 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 that the previous project would be restarted.
Months of work, looking for things that might go wrong.
It was probably because of this operation that the ulterior Plan Wheeler became frightened. 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 Pullan Wheeler. The National Academy of Sciences will then come forward and ask the International Society for Theoretical Physics to put pressure on the American Physical Society to force the other party to find and hand over Pullan Wheeler, but in any case
, we are in a big stumble this time.”
After Professor Coppert explained the situation angrily, he said bitterly: "Because of that damn Plan Wheeler, our progress in the past three months has been wiped out. 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 less obvious advantages will be completely eliminated."
Qin Ke consoled him: "Professor Kopet, the situation is not too bad. Even if the other party obtains the information, the useful information is only based on our previous mathematical model deduction and the data verified by your team's research. The most critical mathematical model is still there.
Without our mathematical models in our hands, Qingjun and I would have difficulty making new breakthroughs."
He pondered for a moment and suggested: "Professor Koppet, 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, it is because
It is mainstream and relatively mature, which makes the competition extremely fierce, and it is difficult to have particularly eye-catching results that surpass others. Incidents like this are more likely to occur, making the research results a stepping stone for others. I suggest,
How about trying another direction?"
"New direction?" Professor Kopet frowned: "Q does it refer to topological superconducting vortex state, single layer/interface and heterojunction topological superconductivity, or topological quantum computing based on two-dimensional electron gas?"
This chapter is not finished yet, please click on the next page to continue reading the exciting content! These three are new research directions in the field of topological quantum computing that have only been proposed in the past ten years. Currently, no national scientific research institutions have achieved great results.
But there is no doubt that these three new directions are very viable, but because of the weak foundation, 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 will not be too difficult to prepare artificial topological superconducting materials from this topological insulator.
High, and entering quantum computing from this direction can reduce a lot of workload. The most important thing is that this direction is most suitable for using mathematical modeling, and can better bring out the advantages of Qingjun and me."
The biggest problem in quantum computing is that interference from the environment makes the quantum state unstable and unpredictable errors occur in calculations. Topological qubits composed of "Majorana zero-energy modes" can solve this problem in principle, and topological superconductors
There is a Majorana zero-energy mode on the surface of the vortex center, which is also the theoretical basis for the "topological superconducting vortex state".
Professor Koppet pondered: "This proposal is very attractive, but the matter is very important. I need to summon everyone in the research team, including you and Dr. Ning Qingjun, of course, to discuss it. In this way, we will spend three days to discuss it."
We will discuss the feasibility, and three days later, we will have a video conference to decide whether to change the research direction to topological superconducting vortex states."
After ending the call, Ning Qingyun asked curiously: "Qin Xiaoke, if I remember correctly, you have been asking me to see the information on topological superconducting vortex states before, right? You have wanted to make this suggestion for a long time?"
"That's right." Qin Ke smiled.
He did have selfish motives in making this suggestion.
The S-level knowledge that the system previously rewarded him with, "The Whole Process of Making a New Type of Carbon Crystal Composite Nanomaterial Suitable for 1nm Chips," involved the details of artificial topological superconductor materials, and the method for realizing quantum computing was
Topological superconducting vortex state.
It's just that it's not detailed enough, and Qin Ke had a hard time reading 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 fully understand this S-level knowledge.
If Professor Kopet, an academic leader in quantum theory, instead studies the direction of the topological superconducting vortex state, it will be of great help to Qin Ke. At least the research results achieved by Professor Kopet's team will be greatly improved.
It deepened Qin Ke's understanding of "the entire production process of a new type of carbon crystal composite nanomaterial suitable for 1nm chips" and laid 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 her while practicing painting, suddenly sighed like an adult: "Brother, Sister Ning, I can't understand what you are saying more and more. I feel like there is a generation gap with you, and I am very depressed."
When Qin Xiaoke came to the nursing home, he got along very well with Grandpa Ning, Ning Jingguang, and Grandma Chu, Chu Mimei. After all, the little girl was innocent, lively and smart, and was very good at pleasing the elderly. She also brought a group of Qin Ke and Ning
The rapeseed and tomato seeds developed by Qingjun were planted in flower pots with two elderly people, which made the two elderly people laugh often.
Ning Qingyun hadn't seen her grandparents smiling so happily for a long time, so she was grateful to Qin Xiaoke from the bottom of her heart. She hurried over and gently touched 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 sanatorium is located 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 a favorite place for the elderly in the sanatorium.
Qin Xiaoke actually just wanted to act coquettishly. When he saw Ning Qingyun doting on him, he immediately narrowed his eyes and shook his head and said: "No, sister Ning, you and my brother can continue to do research. I don't understand, but look
I am happy that you are happy."
Qin Ke remembered that he had not taken this little girl out to play much during the whole summer vacation, so he thought for a while and said: "I will take you to various villages tomorrow, which is an outing. By the way, I will learn about the new seeds on the market in the countryside.
Real response.”
This proposal received enthusiastic responses from both Qin Xiaoke and Ning Qingyun.
So in the next three days, Qin Ke drove himself to several nearby towns with the best sales of new seeds more than 100 kilometers away. Sure enough, he found that new corn, rapeseed, and rice all had large planting areas.
, especially rape, can use natural compost to achieve green and high yields, reduce the cost of chemical fertilizers, and has a sweet and refreshing taste, which is very popular among farmers.
Although the yield of rice is slightly lower than that of mainstream hybrid rice on the market, it is superior in terms of fertility requirements, pest resistance, and herbicide resistance, making the planting profit higher at the same cost. Many farmers have begun to try it.
Planting.
Qin Ke once asked an old farmer outside a seed store: "Old man, why did you buy dozens of bags of corn seeds at once? This can at least plant twenty 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 there was a girl wearing sunglasses and a hat next to him. She looked like a child in the city, so he smiled and said:
"You kids from the city also care about farming? My kid recommended it. He said it was developed by two of the most talented students, and these two genius students also have special consciences. As long as they identify it, it is theirs."
After researching the results, you can buy it with confidence. I have also bought the tomatoes they studied before. It is really easy to grow. It can grow on wasteland. In mature soil, the yield is higher than what I have grown before. So this time I heard that there is
The new seeds they invented, I quickly came to buy them."
These words made Qin Ke and Ning Qingyun feel 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 brands. They just looked for the "
According to Qin Ke and Ning Qingyun’s patented production, they bought seeds for planting with trust.

After leaving the seed shop, Ning Qingyun sighed softly: "Although it can improve the lives of farmer uncles, which makes me feel that the research is particularly meaningful, I also feel a sense of sincerity and fear.
I feel like I’m afraid of betraying this trust.”
Qin Ke rubbed his nose and smiled: "Just turn this trust into motivation. Use scientific research results to change the world and make the world better. Isn't this our goal?"
Qin Xiaoke comforted her: "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 sanatorium. Qin Ke and Ning Qingyun participated in Professor Kopet's video conference after dinner. After collective discussion and deliberation, a new consensus was finally reached, and the research direction of topological quantum computing was changed to "
"Topological superconducting vortex state" and began to carry out new research intensively.
This was good news for Qin Ke. In the next few days, he and Ning Qingyun plunged into this new direction of topological quantum computing, exploring theoretical directions with Professor Kopet's team, and deducing
and perfect.
Time has come to the end of August in a blink of an eye, and Qin Ke and Ning Qingyun are about to return to the capital to start their lives as graduate students in the physics department.
The IMU also sent new news, consisting of Professor Faltings, Professor Tao, Professor Linden Strausch, Professor Wiles and other 30 highly authoritative mathematics experts in the direction of analytic number theory.
The "Riemann Hypothesis Five Expressions Jury" has actually been established, and will review Qin Ke's papers on the first four groups of expressions in the next month, and the fifth group that has been submitted to the "Annals of Mathematics" but has not been published.
Expressions and their derivation are reviewed centrally.
One month later, the review team will invite Qin Ke to have a video connection for a formal "defense."
The review results, together with the "defense" results, will become the final basis for IMU to finally admit that Qin Ke has proved the Riemann Hypothesis.
The wonderful and tense golden autumn of September, together with the new semester and the new postgraduate life, will soon kick off.
I'm too busy at work today and have been working overtime. It's after nine o'clock in the evening when I get home from work. I apologize for the late update. I will revise it carefully when I have time to correct possible typos.
Recently, there have been only one update with more than 4K words. It is really because I am too busy at work. With the mask factor, having a job that can barely guarantee basic necessities of life without delaying wages is extremely precious, so even if it is silently reduced by 10
% of his salary, Lao Mo can only continue to grit his teeth and endure it, and work harder overtime. This is life.
Well, in short, I wish everyone’s work, life and study will get better and better. As long as you work hard, everything will get better and better. Let’s encourage each other.
