Two days later, in the early morning, Qin Ke and Ning Qingyun met Professor Roger Coppert in the office of the Mathematics Department of the University of Munich.

Professor Koppet is about fifty or sixty years old. He is a typical Germanic person. He is tall and has a serious expression. At first glance, he seems to be an unsmiling and somewhat rigid person, but he is absolutely rigorous.

When he saw Qin Ke and Ning Qingyun exchanging greetings, he directly asked in English: "Are you Qin Ke?"

"Yes. Hello, Professor Kopet. This is a letter of recommendation from Mr. Faltings. Because I want to find a partner on quantum computing projects, he recommended you to me." Qin Ke used a different word this time.

It's German.

Hearing the familiar native language, the resistance and coldness in Professor Coppet's eyes faded a little. Although he can speak English, there is no doubt that German will make him feel more comfortable and make communication easier.

Professor Coppet did not accept the recommendation letter from Qin Ke, but just stared at him and asked: "You majored in physics and you are only a sophomore this year?"

Qin Ke said, neither humble nor arrogant, "Yes."

Professor Koppet raised his eyebrows: "Then do you know that in my team, we basically require doctoral students and postdocs?"

Qin Ke met his eyes without giving in: "If Professor Coppet judges a person's actual ability based on academic qualifications, I think I can leave. Such a superficial person is not qualified to be my partner."

Professor Coppet looked at his confident expression and thought that this guy was quite interesting. He obviously came to ask for cooperation, but he always maintained an attitude of equality.

"Let me ask you, a sophomore physics freshman, do you understand quantum science?"

"I have self-study all professional courses in quantum physics and quantum information science. In terms of quantum science, I should be no worse than any of your doctoral students."

Professor Coppet burst into laughter. He had indeed heard of Qin Ke’s reputation in mathematics for a long time. However, a mathematician who was only twenty years old and had achieved such outstanding results in mathematics said that in physics, especially in comparison with other recognized

In terms of difficult quantum theory, can it be comparable to the doctoral students you brought out?

This bragging is a bit too much.

You must know that the doctoral students he brought out are more than enough to become lecturers in other schools, and some outstanding ones can even be directly hired as associate professors.

He pulled up a blackboard and wrote an equation: "Ψ"

"Complete the equation represented by h and show me."

Qin Ke smiled faintly, took the pen and finished writing in just a few seconds.

"?^2/2m·?^2/?x^2 v(x,t)"

"Professor Koppet, you have the kindness to think about such a simple single-particle one-dimensional Schrödinger equation. How do you look down on me?"

Qin Ke said and wrote down another set of equations that were several times more complicated:

"Ψ(x,t)=∫[c1(e)ψe,1(x) c2(e)ψe,2(x)]e^(?iet/?)·de"

Professor Koppet's imagination shrank slightly. This is the relationship between energy e in the stationary Schrödinger equation and two linearly independent solutions ψe,1(x), ψe,2(x). He can easily write it out

From this equation, it can be seen that Qin Ke has a deep understanding of the stationary Schrödinger equation, eigenwave functions, Sturm-Liouville theory, and the eigenproblems of the Hermitian matrix.

Professor Koppet asked questions one after another, ranging from quantum mechanics, tunneling effect, quantum entanglement, quantum system, quantum oscillator, to Hilbert space, Laplace operator, Fourier optics and propagation of light.

Nearly twenty minutes.

Qin Ke answered questions fluently throughout the whole process and drew inferences from one instance to another, allowing him to have in-depth exchanges with Professor Kopet.

At this time, not only Professor Kopet was greatly moved, but even the assistant next to him was stunned, because later on, Professor Kopet's questions became wider and wider, and became more and more partial. Even Professor Kopet

The best doctoral students taught may not be able to master everything in such a comprehensive way!

But the mathematician from Xia Guo, who was only about twenty years old and still in his second year of undergraduate studies, actually did it!

This is simply unbelievable. Has the Xia Kingdom’s physics community quietly developed to such a powerful level? Or is this young mathematician from the Xia Kingdom, known as the “Miracle Boy”, also a genius in physics?

Professor Koppet couldn't help but sigh in his heart. No wonder Faltings dared to recommend this young man as his project partner. This young man has an extremely solid foundation in quantum theory and has almost no blind spots. He is very knowledgeable about quantum theory.

He is well aware of all sub-branches of scientific theory. The only thing he lacks is the grasp and understanding of experimental details. This should be related to the fact that he has not conducted many relevant experiments.

However, it is simply a miracle that one can master quantum theory by self-study to such an extent just from textbooks and literature.

As expected of a genius mathematician who was able to prove several world-class mathematical conjectures at a young age and won the Crafford Prize. His talent in science is simply enviable. At least Professor Coppet himself, at the same age,

Not even half of the opponent's level.

Professor Koppett's expression has softened greatly. Qin Ke's level of quantum theory alone would make him join his research team.

But what Professor Kopet needs most is mathematical ability to help him solve the bottleneck problem.

"Qin, I know that you are very good at theoretical mathematics, especially number theory, which is among the best in the world, but I don't understand your level in functional analysis, topology, probability, and mathematical modeling. You know

, the key core of my topic on topological quantum computing is the study of quantum entanglement, which requires massive data analysis and modeling to confirm my hypothesis and improve the theory."

Unknowingly, Professor Koppet's name for Qin Ke has become the more affectionate "Qin", which is a recognition of his physics level.

Qin Ke smiled and said confidently: "Although the international papers I usually publish are related to number theory, mathematical analysis is my specialty, especially mathematical modeling. Not only me, but also my partner next to me is also a mathematician.

An expert in modeling. If you agree, she can join me in this cross-border project and work together on this project. Don’t forget, she is also the winner of the Crafford Prize.”

As he spoke, Qin Ke took out a thick printed paper, which was the English version of the paper he had submitted, "Using the Karman Vortex Effect to Study High-Throughput Preparation of Ultrafine Fibers."

"This paper has been submitted to "Natural Materials", and we are responsible for all data analysis and mathematical modeling."

Qin Ke took out three more Chinese versions of computational fluid dynamics papers: "These are papers related to computational fluid dynamics, and they are enough to prove our ability in mathematical modeling."

Professor Coppett carefully flipped through the English version of the paper, and the look in his eyes gradually became serious.

He thought for a moment and looked directly at Qin Ke: "You have basically convinced me, but because I have been deceived by a mathematician once, this time you and your partner want to join my research group, you must go through a month of

During the probation period, if your performance during the period satisfies me, I will allow you to officially become an important member of my team, and the final project results will be signed and shared with you based on your contribution."

Given Professor Koppet's status in the German physics community, it is extremely rare to be able to collaborate on a research project with a mathematician who is not well-known in the international physics community and also promise to co-sign and share the results of the project.

Qin Ke breathed a sigh of relief, knowing that this was the most ideal result. He stretched out his hand and said with a smile: "Okay."

Professor Coppet also stretched out his hand and shook his hand vigorously.

"Before that, please allow me to say that you are welcome to join my topological quantum computing research group. Our goal is to achieve breakthrough results before the middle of next year, achieving the highest tolerable logical operation error rate in quantum error correction.

Elevate it to a level where quantum computing can be performed under experimental conditions!”

…

Qin Ke and Ning Qingjun stayed at the University of Munich for another two days, mainly to follow Professor Koppet and his team to familiarize themselves with the topological quantum computing topic and some necessary experimental operations.

Although theoretical physics is mainly based on theory, physics is inseparable from experiments. The topic of topological quantum computing also requires experiments to verify the final results. Professor Koppet can apply to use the quantum computing laboratory at the University of Munich, which is the leading quantum computing laboratory in Germany.

.

In these two days, Qin Ke and Ning Qingyun's level of physics and mathematics also successfully impressed Professor Kopet's team. The dozen or so doctoral students in the team, who had their eyes high above their heads, were impressed by the two.

When I left, I no longer had any contempt and resistance, but I kindly accepted these two young college students from the far Eastern countries and became important members of the team.

——The world of physics, like the world of mathematics, always relies on strength, especially in a country as rigorous and rigid as Deguo. Without strength, even if you have strong back-end connections, you will not be recognized and accepted by others.

The strength of Qin Ke and Ning Qingyun undoubtedly achieved this.

After dividing the work and agreeing to communicate through encrypted emails, Qin Ke took Ning Qingyun to say goodbye to Professor Kopet and others, returned to Bonn, and continued to participate in the remaining academic lectures.

Qin Ke’s report at the academic lecture of the Humboldt Research Award was still the fourth set of expressions of the Riemann Hypothesis.

Bornhard Riemann is one of the most famous and greatest mathematicians in Germany. In his hometown, giving an academic report on the Riemann Hypothesis will naturally cause a strong sensation.

The original video of Qin Ke's lecture at the Crafford Prize has been circulated on the Internet. Many mathematicians from the winning country have already watched it once, but they still came to Bonn to listen to the lecture again.

The reputation status of Riemann's hypothesis in German academic circles is similar to the status of Goldbach's hypothesis in Chinese academic circles. They are both major mathematical issues that are well known to the whole people and are of national concern.

Therefore, Qin Ke's academic report naturally became the most popular one in the entire Humboldt Research Award academic report conference. More than half of the mathematicians in the country's mathematics community were sitting in the audience, listening to this young man who was too young.

The Xia Guo mathematicians revealed the mystery of the Riemann Hypothesis that they were most proud of and most eager to understand.

Among these mathematicians, some are disapproving, some are full of curiosity, some are confirming their ideas, some are excited and looking forward to it, and some are deliberately trying to find fault. After all, there are so many mathematicians in the country who are studying the Riemann Hypothesis that they can at least account for all the mathematicians in the country.

One-fifth of the world's peers.

When Qin Ke began to give his report, there were even some arrogant "civilian mathematicians" who gave out imperceptible sarcastic smiles. In their eyes, only outstanding Germans could crack such a great proposition as the Riemann Hypothesis.

Qin Ke was already aware of the possible consequences of making such a report in Riemann's hometown. He was calm and unhurried, and explained in detail the derivation process of the fourth set of expressions of the Riemann Hypothesis in German.

Originally, with his intermediate level of German, he was unable to give such a professional mathematics report fluently, but he made preparations in advance and translated the entire speech into German through Glimmer, and asked a German professor at Qingmu University to help revise it.

You only need to memorize the unfamiliar words and sentences, and it will naturally not be difficult.

The final result was very good.

No one expected that Qin Ke would give a report in German, which made the audience easier to accept. When they saw the rigorous and flawless derivation process, they saw the young boy on the stage scolding Fang Qiu.

and confidence, slowly, the critical and disapproval in the audience's eyes disappeared, replaced by shock, excitement, wonder, and admiration.

At the end of the report, the audience was silent at first, and then a storm of applause rang out from every corner of the venue, eventually filling the entire venue.

Facing the wave of applause, Qin Ke smiled, took off his hat and bowed slightly in a gesture of gentlemanly etiquette.

This scene was photographed by reporters.

This chapter is not finished yet, please click on the next page to continue reading the exciting content! The next day, "World Academic Journal", the country's largest circulation and most influential academic newspaper, published a report titled "He

"The report conquered the mathematicians in Bornhard's hometown!" The picture is Qin Ke's very beautiful bow and thank you, and in the background is the audience cheering and applauding excitedly.

At the end of the report, it was commented: "Hundreds of mathematicians from all over Germany were present and tried to find loopholes in the report of the Xia Guo mathematician, but unfortunately, until the end of the entire report meeting, no one

Being able to do this means that the miracle boy from Xia has successfully uncovered two-thirds of the mystery of the Riemann Hypothesis. Perhaps in the near future, we will be able to fully see the full picture of the Riemann Hypothesis.

let us wait and see!"
