After Xu You told Lou Song that he was sure to participate in the digital competition training camp, Lou Song was also very happy.

If you can study with friends of high-level levels like Xu You, Lou Song's learning efficiency will become more efficient.

"Did you realize that there are not enough physical tools?" Lou Song said with a smile.

After spending so long with Lou Song, Xu You knew that this was a kind of ironic joke by Lou Song.

There has been a long debate among students in the Department of Mathematics and Physics about the status ranking of the two disciplines.

Many students in mathematics mistakenly believe that physics is the application of applied mathematics.

Many students in physics also naively believe that mathematics is a tool of theoretical physics.

Objectively speaking, the importance of these two subjects is unquestionable.

In terms of status, it is impossible to accurately compare.

But Xu You always believed that learning mathematics well will definitely be of great help to physics.

"No, mathematics is the mother of all subjects. Although I definitely can't join the national team in the mathematics competition, the training process is also very meaningful."

"That's it. No matter who the final quota is given, we both strive to win the top two in the selection competition."

"Hehe, my target is not just the top two."

"Oh? Then I'll wait and see."

After the competition training began, Xu You, Lou Song and other members who were selected as the competition training team in the competition competition came to the classroom one after another.

Like the training camp for the Football Competition, there are also some students who are not selected for the National Gathering, who have obtained the qualification to be the attendant after passing the application.

The selection process of the official players of the National Team of Digital Competition is divided into two stages.

In the first phase of the training, 15 team members will be selected to participate in the next second phase of the training.

In the end, 6 national team members were competed for the 63rd IMO.

Lou Song is undoubtedly the most eye-catching one of the most competitive players in this class.

Not only was he very young, he also won the first place in the CMO national final with full marks.

Xu You's reputation is also very famous.

Not only did CMO score in the top few, but he also won the first place in CPhO at the same time.

Because of his roommate, Xu You and Lou Song naturally sat together.

After losing the pressure of ranking, Xu You's mentality was very relaxed.

It is entirely for the purpose of absorbing mathematical knowledge and enjoying the fun of solving problems.

In the first stage of the selection, Xu You and Lou Song advanced without surprise.

During the second stage of training, the overall training intensity has been increased to a higher level.

But for Lou Song and Xu You, this feeling is even more enjoyable.

The second phase of training content, including the IMO question 6 in 1988, was not solved by even the host number theory expert at that time.

In addition, among the 615 contestants in 2017, 608 people did not even get a single point in the IMO third question.

Xu You and Lou Song successfully got full marks in training for all these difficulties.

In the final second stage of the selection competition, Lou Song still got full marks when he handed in the paper three hours in advance.

Although Xu You's speed was much slower than Lou Song, he also got full marks and tied for the first place in the selection competition with Lou Song.

The moment I saw the results, the leaders and coaching staff of the National Team of the SUP national team were both in a tangle.

It was naturally as expected that Lou Song could get the full mark.

But no one could have thought that a student like Xu You, who focuses on competition, could get full marks in the IMO-level selection competition.

Faced with Xu You's achievements, some members of the coaching staff even had the idea of ​​trying to win over it.

"I think it's time to change the system of a player who cannot be selected into the national team in both subjects in the same year."

"But who would have thought that a student could have so much energy to learn both subjects so well?"

"If you want to change, you have to wait for the next session at the earliest. The system has been set, and even if there are problems, it is impossible to change it suddenly now. This is really unfair to other students."

After careful discussion, the coaching team made an unanimous decision and implemented it according to the original system.

Even if Xu You is unable to be selected into the National Team of the Digital Competition, it is indeed a pity.

But we cannot break the rules set early.

Xu You was very open-minded about this, anyway, he had known about this before.

The training camps these days have indeed learned a lot, and this trip is definitely worth it.

In the end, because Xu You has been selected for the national team for football competitions, the seventh place will be replaced by the national team for digital competitions in China.

"Don't worry, even if you don't go, the number one must be from our China."

"Of course, with you here, I can go to IPhO with confidence."

I thought of the future that I could represent China, compete in international competitions, and win glory for my country.

Xu You and Lou Song are both looking forward to it.

After the training camp for the number competition.

Xu You reexamines his subject level.

【Mathematics: 228↑】

【Physics: 258↑】

"Mathematics has actually exceeded 200 points?" Xu You couldn't help but exclaimed as he looked at the data on the system interface.

Although Xu You didn’t know what kind of ability the 200-point subject level meant.

But Xu You remembered that when he won the CPhO championship with full marks.

The subject level of physics is only 208 points.

And at that time, Xu You felt that the question of the CPhO national finals was a bit simple.

"No wonder I got the full marks so easily this time."

In addition to the rapid improvement of mathematics.

Xu You also noticed that his physics discipline level was also quietly improving.

You know, during this period, Xu You never touched physics at all.

"Did I say that the improvement of my math level has allowed me to break through the bottleneck of physics?"

Xu You thinks that there is indeed such a possibility.

After returning to the dormitory, Xu You picked up information about physics again.

I haven't touched physics for a month, but the feeling of reunion after a long time is even more wonderful.

Xu You also clearly felt that his thinking was much broader than before.

Taking advantage of his good condition, Xu You continued his previous research questions:

How to stably implement a high-dimensional quantum gate of any single photon.

This problem is not only a physics problem, but also a mathematical problem.

In fact, in previous research, Xu You has basically made a general solution to the problem from a physical perspective.

However, in the construction of specific matrix, it has fallen into a stagnation.

At this time, Xu You turned on the deep learning state, increasing the brain's power to the maximum.

"Based on the basis of the classic Pauli Gate, adding dimensions should enable the transformation of high-dimensional quantum states."

"By the way, Bloch's sphere!"

Suddenly, Xu You thought of such a geometric representation.

This is in quantum mechanics, a geometric representation of pure state space in two-state systems.

After Xu You drew the Bloch sphere on the draft paper, he quickly had a clear idea.
Chapter completed!
