I really just want to be a scholar

Chapter 707 The development of quantum computers will enter a new era!
Qin Ke and Ning Qingyun only stayed in Yuanzhou for two days before flying back to the capital.

During the three days in Yuanzhou, apart from organizing a birthday celebration for Qin Xiaoke and attending the school board of Qingning Private High School, the two spent most of their time on the Qingning Student Aid Foundation.

After the last asset inventory, Qin Ke found that the operating efficiency of the Qingning Student Aid Foundation was still a bit low, and a large amount of cash was lying on the account, causing a great waste of resources.

So when he returned to Yuanzhou this time, Qin Ke found several main directors of the Qingning Student Aid Foundation, including grandfather Shen Tieshan, Wen Jianzhao, Shi Cunyuan, Lin Haibo, and the secretary-general Huo Baoyan who came back early, as well as a video conference in the capital. Deng Hongguo, who attended the meeting, held an important meeting together.

The theme of the meeting is to expand the scope of funding projects of the Lime Student Aid Foundation, and actively recruit talents from all provinces who are enthusiastic about student aid and charity work to join the Lime Lemon Student Aid Foundation.

At the meeting, Secretary-General Huo Baoyan first made a detailed work report.It has been almost four years since Lime Student Foundation was established. At present, there are 30 official officers and 110 nine assistance projects, including 1000 "full assistance projects" and [-] "general assistance projects". Two, with a total expenditure of about [-] million yuan.

"Complete assistance project" refers to the student aid foundation's contribution to help the school rebuild the teaching building, office building, staff dormitory, playground, small library, etc., and will bear the living allowance of the students and the additional living allowance of the teachers in the mountain village.For example, Shicun Qingning Primary School and the dozens of mountain village schools on the prairie are fully aided projects.

The "General Assistance Project" is relatively simple, and the student aid foundation is mainly responsible for the living allowance of students and the additional allowance of teachers.These assistance projects have not yet completed the review and planning of the school building reconstruction plan, and are in the early stage of assistance. In the past year or so, the newly recruited local officers in various provinces have been responsible for finding mountain village primary schools that need funding.

Because the funding approval of the Lime Scholarship Foundation is very strict, and the system process is also very standardized, it will take at least half a year for the review to be converted from a general aid project to a full aid project.

The lack of manpower led to a long review process, which is also the main reason why the Lime Student Foundation has only spent about [-] million yuan in the past four years.

What Qin Ke wants to do now is to increase the number of officers, expand the funding area and number of "general assistance projects" as much as possible, at least ensure the normal living and learning conditions of primary school students and supporting teachers in impoverished mountainous areas across the country, and at the same time increase Talents in funding review can speed up the transformation of general aid projects into full aid projects.

After listening to the report, Qin Ke strengthened his mind again, and he gave his own suggestion at the meeting:

"I think the Lime Student Foundation can make bigger strides. The manpower should be expanded by at least five times on the current basis. First, we should try our best to benefit the children from famous districts in all provinces across the country. Don't be afraid of problems. Next time Starting this month, the foundation will set up an additional discipline inspection and audit team to go to various projects to conduct audits, whoever dares to stretch out their hands will not only spit out their belt bones, but also lose their reputation and ruin their future!"

The rest of the people also found that the foundation had too much balance and could not play its due role, so they all agreed with Qin Ke's proposal.

The meeting lasted for about two days, and discussed in detail various rules and regulations, recruitment requirements for officers, auditors, and audit team members, and work procedures.

After the meeting, Qin Ke and Ning Qingyun became hands-off shopkeepers again. After all, whether it was his grandfather Shen Tieshan, or Deng Hongguo, Wen Jianzhao, Shi Cunyuan, Huo Baoyan, etc., they were all people with rich social experience and practical spirit. The strategy can be carried out smoothly without the two of them needing to bother.

Moreover, the two of them did not have so much time and energy to devote to the daily affairs of this student foundation. The time for the topological quantum computing research topic is still a bit tight. The competitive pressure from the team of Professor John Krause from the University of California made Qin Ke and Ning Qingyun also had to pay attention to it and speed up their research on topological quantum computing.

……

It was already mid-December after the two of them arrived in the capital, and the first snow fell in succession in the capital. The temperature dropped so badly that the whistling wind could be heard outside the windows all night. The attendance rate of various courses in Qingmu University Significant decline, Qin Ke and Ning Qingyun's mathematics courses in Qiuzhen Academy, and the "You ask me to answer" question-and-answer courses in the Department of Physics and Department of Mathematics still maintain a relatively high attendance rate.

Severe weather has swept across the country from north to south. The temperature in the capital has dropped below minus 10 degrees Celsius. It is full of snow as far as the eye can see. The world seems to have become a world of ice and snow. The meteorological department has issued a red cold warning signal in advance, and there are many more The media has begun to speculate whether this winter will be as severe as the extremely cold one three years ago.

As the cold wave went south, snow began to fall in many places across the country. Even if the southern cities hadn't snowed for a while, the cold wind was already howling, and the green plants everywhere were in a bleak scene.

Contrary to the cold weather, the academic and research circles are very lively.

Various year-end summary meetings, various award ceremonies, and various exchange meetings emerge in endlessly. Many experts, professors and scholars are moving around. There are a network of relationships that are sophisticated in the world.

Qin Ke and Ning Qingyun, as the most famous and popular young scholars and first-class professors in Xia Guoli today, have naturally become the darlings of the academic and scientific research circles, and countless invitation letters are sent to Qingmu University every day.

The organizers of various conferences also showed their talents, finding connections by beating around the bush, or asking acquaintances or friends to contact them, just so that Qin Ke and Ning Qingyun could attend their conferences, even if they didn't give speeches on stage, as long as they could show their faces It can add a lot of luster to the meeting.

But how could Qin Ke and Ning Qingyun have the time to attend these miscellaneous meetings, and they were not as keen on socializing as some professors in order to expand their network and influence, so the vice president of Qingmu University, Gu Bojun, declined them all.

At this time, the Fluid Mechanics Laboratory is basically in the state of early vacation. This year, the national-level scientific research projects and the scientific research projects independently applied for have been completed in November, which makes the researchers who are used to being busy from the beginning of the year to the eve of the Spring Festival I'm not used to it.

Apart from occasionally choosing some important meetings to attend, Jiang Weixian and Academician Guo Weiyang spent the rest of their time drinking tea and chatting leisurely in the office.

The two old academicians have been busy all their lives, have they ever tried to have such "boring" free time?Academician Guo Weiyang also jokingly said: "Qin Ke, thanks to you and Xiao Ning this year, all the research groups in the entire laboratory have completed their tasks ahead of schedule, and it is also the first time for everyone to experience what is called excessive advance. It's refreshing to complete the task. I'm not afraid of anything else now, but I'm afraid that something will happen to them."

Qin Ke was a good person, and immediately under the name of "Academician Guo's Proposal", he arranged for each research group to strengthen the learning tasks of mathematics, especially NS equations and mathematical modeling, which attracted a lot of wailing and Guo Weiyang Caught him laughing and cursing a few words.

There is nothing to worry about in the fluid mechanics laboratory, and the lime plant breeding laboratory has slowed down the speed of plant seed breeding research.

All the researchers, including Wei Xueming, are concentrating on the in-depth study of "Computational Seeds Course", in order to truly master this great subject.

For this reason, the Lime Plant Cultivation Laboratory also recruited three additional doctors of mathematics from Yanda University and Zhejiang University, as well as three veterans in computer programming.Wei Xueming issued a "military order" to Qin Ke, and the plant cultivation laboratory will basically be able to independently conduct seed hybridization experiments through computational seed science before July next year.

Of course, he also made a request to ask Qin Ke and Ning Qingyun to spend half a day every weekend to explain computational seed science to researchers in the plant breeding laboratory, so that researchers can master computational seeds faster and better. study.

Qin Ke agreed immediately.

In addition, Qin Ke and Ning Qingyun only had the usual two sessions of "You ask me to answer" questions every week, and they went to Qiuzhen Academy to give lectures.

Relatively more free time allows the two to devote more energy to the topic of topological quantum computing.

The morale of the Quantum Computing Laboratory of Lime Technology is currently high, because the most ideal Majorana fermion carrier has been synthesized. Seeing that there is only one step away from success, the researchers in the laboratory seem to have been beaten. Almost 24 hours in two shifts, they kept on carrying out experiments according to the experimental plan of the two, and then quickly fed back the experimental results to help Qin Kening and Qingyun optimize and perfect the theoretical model system at hand.

Qin Ke also took Ning Qingyun to the quantum computing laboratory almost every night, personally guiding the experimental work on the spot.

Now Qin Ke's physics level has been raised to "master level", and his knowledge and thinking level in quantum mechanics are comparable to or even slightly surpassed by a quasi-Nobel Prize-winning expert like Professor Kopet, and with the help of Ning Qingyun, Together with the sincere cooperation of [-] laboratory researchers including Harold, Ling Shaotang, and Gan Peixuan, the research on the last difficulty of topological quantum computing - "Precise regulation of Majorana zero-energy mode weaving operation" has progressed very smoothly. .

But Qin Ke is still racing against time. This is no longer just about catching up with Professor John Krause's team. The dawn of success is getting closer and closer, and Qin Ke also has another new goal in mind.

He wanted to use the results of the project "Topological Quantum Computing" as one of his proposal gifts to Ning Qingyun.

Among the scientific research projects that the two are currently working together, "Topological Quantum Computing" is the closest to success and the most promising to be completed before his birthday.

In the blink of an eye, the time has entered December 12nd, and there are only two days left before Qin Ke's 22nd birthday.

It happened to be Saturday, but Qin Ke didn't take a vacation as usual, and took Ning Qingyun to enjoy the two-person world exclusively for them. Instead, he stayed in the quantum computing laboratory and carried out the final research at full speed.

To achieve the goal of "precise control of Majorana zero-energy mode weaving operation", the key is to use topological gaps to control the fusion and weaving of anyons, so as to eliminate the biggest obstacle to the generation of topological qubits and achieve high fault tolerance of long-range entanglement in the ground state .

do not understand?To explain it in a simpler sentence, it is the ability to create and maintain quantum phases through measurable topological gaps based on Majorana zero-energy modes.

What Qin Ke and the others have to do now is to create a complete theoretical model of "topological gap" to realize the precise regulation of Majorana's zero-energy mode weaving operation.

Here's an explanation of the "topological gap," a characteristic energy that controls the fidelity, speed, and size of a topological qubit.The premise of generating the "topological gap" is to generate a reliable and continuous quantum topological phase through the most ideal Majorana fermion carriers, and to verify through experiments that the subcomponents of the qubit are in the long-range entanglement state of the ground state.

The pointer of time has moved to 23:00 in the middle of the night, and the eyes of most people in the laboratory are covered with bloodshot eyes. From last night to now, everyone present has not closed their eyes for more than 24 hours. Subtle operations, and there are large pieces of manuscript paper scattered around - this is the record of Qin Ke and Ning Qingyun's calculations on the spot.

But no one cared about cleaning up the somewhat messy laboratory environment. Everyone was focused on the final result that was about to appear in the quantum computing measurement and control system.

Ning Qingyun was no exception. She subconsciously held Qin Ke's big hand firmly, looking at the system's measurement and control interface with a nervous and expectant expression.

Finally, after numerous flashes on the interface of the quantum computing measurement and control system, a line of English was displayed—"Success!"

Then there is a detailed list of experimental results data!

Seeing the word "Success!", after a brief silence, the entire laboratory suddenly erupted into hoarse carnival and strange screams!
"Successful! Successful! We finally succeeded!" Harold jumped up excitedly, hugged Ling Shaotang next to him vigorously, opened his arms again, and hugged Qin Ke vigorously:
"Professor Qin and Professor Ning, you are amazing! You have discovered such a small problem. Without you, it would have taken us at least another month to succeed!"

Ling Shaotang was still staring at the screen, repeating the detailed results above: "The topological gap of 35μeV...the precise operation of optical quantum logic gates with millions of superconducting qubits...quantum tomography and the quantum entanglement measurement of Bell's inequality 99.99% fidelity... perfect! perfect!"

He suddenly blushed and turned to look at Qin Ke and Ning Qingyun: "Professor Qin, Professor Ning, I, Ling Shaotang, have never been convinced before, you two are the first and the second!"

The rest of the people also surrounded Qin Ke and Ning Qingyun and shouted wildly with excitement!

No wonder they were so excited.These days, Qin Ke and Ning Qingyun have stayed here almost every night, solving the problems found in the experiment as soon as possible, so that they can truly experience the strength of their mathematics level and the rich knowledge of quantum computing theory at close range. and solid.

If it weren't for Qin Ke and Ning Qingyun's continuous improvement of mathematical models and mathematical deduction, the laboratory would have to take countless detours. Just in the conversion between Majorana zero-mode and real fermion operators, it would be difficult Can stump them for a whole year!

Especially in today's experiment, there was a very subtle problem. They discussed it for a long time but couldn't find the reason. In the end, Qin Ke and Ning Qingyun discovered a small problem in the experimental plan through mathematical analysis, and adjusted the laser light accordingly. The power of the exciter.

Only 1.52% of the power adjustment made the experimental results that were constantly reporting errors finally become "Success"!
After a while, the excited crowd calmed down, and their eyes full of approval and expectation fell on Qin Ke and Ning Qingyun.

Qin Ke held Ning Qingyun's white and tender little hand and raised it high, smiling loudly:
"Now I announce that the topic of 'Topological Quantum Computing' has achieved the expected results today and at this moment! We will be the first research team in the world to solve the problem of 'Topological Quantum Computing'. We are based on topological superconductors Supplemented by the combination of topological insulators and along the direction of 'topological superconducting vortex state', a logical and self-consistent theoretical model system has been initially formed, which can achieve a fidelity rate and fault tolerance rate of 99.99% and a million-level Quantum computing with qubits—!"

Warm applause and cheers resounded throughout the laboratory again!

Incomparable pride and pride flooded everyone's hearts!
As we all know, topological quantum computing is the premise and basis for realizing a real quantum computer, but even if countless scientific research teams in the world are concentrating on overcoming this difficulty and realizing a topological quantum error correction mechanism with a high error tolerance rate, no one has been able to fully realize it. It can be done, including the world-leading team of Professor John Krause.

But their team, Lime Technology Quantum Computing Laboratory, today, at this moment, has achieved a great goal that no one else can achieve!
A theoretical model system of topological quantum computing with a fault tolerance rate of 99.99% is officially launched, and the development of quantum computers will enter a new era!
