Shen Qi provided a new set of quantum key setting theory system for the team of academician Pan, and the predictable application scenarios include military, finance, communications, Internet and other fields, which will make hackers with ulterior motives return in vain, the military's contact system will be more reliable, and the people's bank cards will be more secure.

The large-scale application of quantum cryptography needs to rely on quantum basic physics, and it is not an overnight thing for QPU to fully replace CPU, but Academician Pan's team has at least clarified the future research direction, there is a Micius quantum satellite in the sky, and a new quantum key on the ground, and they know very well what to do next.

The theoretical system of "Riemann's Theorem Prime Carrier Quantum Key System" could not be published for the time being, and Shen Qi quietly left the quantum computer laboratory to do something that could be disclosed to the world.

Today is Sunday, Shen Qi has spent a full day in retreat in his hotel room, shifting his thoughts from Riemann's theorem to Riemannian manifolds, forgetting about number theory and quantum physics for a while, and concentrating on algebraic geometry and topology.

"Riemann is a really energetic man, and you can see his name in every field. Based on a fundamental property of Riemannian manifolds, Shen Qi takes the standard orthogonal basis in each tangent space in order to simplify the local calculation.

The topology section of the Hodge conjecture is another major topic that Shen Qi needs to solve when he returns to China this time, and the whole world knows that he is trying to overcome the Hodge conjecture.

The next day, Monday, Shen Qi came to the Morningside Math Center: "Director Wu, brothers, the four-day vacation just ended, you had a good time, right?"

"My wife and I climbed the Great Wall, and this is the eighteenth time in my life that I have been heroes. Director Wu shrugged his nose, he was caught by the cold wind during his eighteenth trip to the Great Wall.

"I didn't go anywhere, I just took the baby at home. A researcher surnamed Liang said.

"I went to Dali, there are a lot of beautiful girls in Tiannan and Haibei, but unfortunately I didn't get a number. Researcher Xiao Bian sighed.

"It seems that everyone's holiday life is quite exciting. Shen Qi smiled.

Director Wu, who is in his fifties, is in his third year of college, and he and his wife choose to go on an outing.

Researcher Liang, who is in his thirties, has just become a father, and he chooses to take care of the baby at home.

Twenty-eight or nine-year-old Xiao Bian is currently single, and he chose to travel to Dali and look forward to an affair.

Director Wu and his fellows generally marry later and have children later, except for singles, most of the rest of the rest of their leisure time is spent with their families.

The men of the Gu family are trustworthy, and Shen Qi learned that five of the other six men in this room are married, three of them are Cancers, they love their wives and children, and they honor their parents and fathers-in-law.

"Where did Professor Shen go?" asked Xiao Bian, a single dog.

"I'm going to travel the capital for four days. Shen Qi, who is unmarried but not single, said, he handed a USB flash drive to Xiao Bian: "Regarding the topological method of Hodge's conjecture, I have written some thoughts in the past few days, and I hope to share it with you, Bian Gong, you can help project it." ”

Shen Qi's experience was projected onto the screen, and Director Wu's six-member team stared at the screen with full attention, the holiday was over, and they returned to work.

Shen Qi began to explain his experience: "The derivation based on the eight standard models of Thurston's geometric conjecture is the core logic that we have determined before. Director Wu, in the past few months, you have completed the derivation of three standard models: standard spherical S, Euclidean space R, and hyperbolic space H^3, and you have encountered difficulties in the left-invariant Riemannian metric on the universal coverage of special linear groups. ”

"The derivation of the Standard Model of the Left Invariant Riemannian Metric on the Universal Coverage of Special Linear Groups is the most complex of the eight Standard Models, and I did a deduction, please see the big screen. Shen Qi switched to the next page and said: "The transition map of the complex manifold is a pure map, I have done a new processing of the Cauchy-Riemann equation, and I got an interesting result, Γ is a one-dimensional complex manifold, and its geometric and topological properties are so different......

Shen Qi spent a whole morning preaching his detailed process and final conclusion on the derivation of the most complex Standard Model.

Shen Qi's first explanation, only Director Wu understood it.

Within a week, Shen Qi spoke six times in a row, combined with new inspiration, he revised while speaking, and finally locked the plan on Saturday, and all six members of Director Wu's team understood Shen Qi's thinking.

"So we've done the derivation of four of the eight standard models, and my suggestion is that we follow my logic of deriving the standard model of the Riemann metric and solve the remaining four standard models. Shen Qi made a summary and gave suggestions.

"Received!" Director Wu's team got the true biography of Shen Qi, and they will complete the rest of the work according to the derivation ideas set by Shen Qi in the future.

Academician Pan's quantum key problem has been solved, Director Wu's topology problem has also been solved, and Shen Qi has left everyone with the impression that he is efficient, responsible, and specialized in treating incurable diseases.

In addition to high-end academic research, Shen Qi is also very concerned about the mathematics education of primary and secondary school students.

The organizer of the Olympiad, the Chinese Mathematical Society, obtained Shen Qi's consent and posted Shen Qi's photo on the homepage of the official website after artistic processing.

This year's CMO is in full swing, with a record number of applicants.

Shen Qi was invited to the Chinese Mathematical Society and undertook an important task --- solving problems.

"Professor Shen, you have won the CMO championship and the IMO championship, all of which are full marks, and the last question of this year's CMO national final is up to you, which is very suitable. The head of the CMO organizing committee said.

"Well said. ”

Shen Qi walked to the small blackboard and picked up the chalk to solve the question on the spot:

Let n be a positive integer, considering S={(x,y,z)∣x,y,z =0,1,2,...... ,n,x+y+z>0} such a set of (n+1)^3-1 points in three-dimensional space, ask: how many planes is required for their union to contain S but not (0,0,0)?

Shen Qi patted the chalk ash on his hand: "Well, this is my question, which is a bit difficult, and it meets the criteria of the last question of the CMO national decision." ”

The other three in the room stared at the blackboard in deep thought.

"This problem is very cleverly set up, using high school math knowledge, plus some non-esoteric extracurricular supplementary knowledge, high school students should be able to solve the correct answer. Vice President Tan was the first to comment.

Shen Qi's old friend Liu Guan said: "Is it possible? I predict that the number of high school students in China who can find the right answer will not exceed a slap in the face. ”

Shen Qi suddenly remembered something: "Leaders, there is a mystery in my heart that has not been solved, how many players got full marks in the last question of the CMO national final I participated in?"

Director Liu said: "Shen Qi, the last question of your national final is too perverted, it is indeed perverted, I remember very clearly, I was reading the paper at that time, and the question required the contestants to prove that the root number 2 is an irrational number, but it is not allowed to use geometric drawing method. Only two of the contestants succeeded in proving that the root number 2 is an irrational number without using geometric drawing, and one of them is Shen Qi. ”

"The question of Root Number 2 is quite interesting, by the way, what is the other player doing now?" asked Shen Qi with interest.

"He was selected for the Olympiad national team and was sent to the Department of Mathematics of Mizuki University, and I don't know too well where he went.

"What's your name?" Shen Qi asked again.

Director Liu: "His name is Yu Lei, and he was selected for the national team in the same period as Shen Qi." ”

"It's him, Yu Lei!" Shen Qi was stunned for a moment, and then laughed: "Yu Lei is currently studying for a doctorate in the Department of Mathematics at Princeton, and his doctoral supervisor is me. ”

"Such a coincidence?" Director Liu and Vice President Tan were both surprised and thought it was fun.

At the beginning, only two high school students proved the most difficult and perverted Olympiad math problem, and now the two are in a teacher-student relationship.

Officer Kong, who had not spoken, finally spoke: "Everyone, let's talk about this question from Shen Qi on the blackboard, Lao Tan, Lao Liu, can you two find the answer to this question?"
