Shen Qi was strolling around the campus of Yan University, and the sky was dripping with light rain.

A black sedan drove to Shen Qi's side and stopped, the rear window opened, and a person sat in the back, he beckoned to Shen Qi: "Shen Qi, get in the car." ”

"Dean Ning, where are you going?" Shen Qi knew this person, the dean of the School of Physics of Yan University and an academician of the Academy of Sciences.

"Get in the car. Dean Ning pushed the door open in the car and couldn't wait to beckon Shen Qi to get in the car.

Shen Qi got into the car, and the car started and left Yanda.

"It's been almost a month since you returned to China this time, when will you return to Princeton?" asked Dean Ning.

Shen Qi said: "The plan is to return to Princeton next week, and it can also be adjusted appropriately according to the actual situation, and it is okay to leave a few weeks later." ”

"There is no need to postpone the original plan, otherwise there is a risk that the American side will be suspicious. Dean Ning said.

"Dean Ning, where are we going?" Shen Qi had a premonition from Dean Ning's serious demeanor and tone, this is going to do something?

"I'm going to the Academy of Sciences for a meeting, it's almost there. ”

The car soon came to the gate of the Academy of Sciences, and Shen Qi was about to get out of the car, when he found two people outside the car who looked unusual.

One of them, who wears glasses and exudes an air of wisdom, is a well-known figure in China's physics community and is the chief scientist of China's quantum satellite project.

"Academician Pan is also coming to the meeting?" Shen Qi was a little surprised, Academician Pan is famous in the international physics community for breaking the world record, and Academician Pan's team recently achieved 18 qubit entanglement, breaking the world record again.

"Yes, Academician Pan learned that you have returned to China, but he does not have your personal contact information, so please invite you to participate in today's symposium. Dean Ning patted Shen Qi on the shoulder and said earnestly: "Shen Qi, the country needs you." ”

Academician Pan and Dean Ning are both big bulls in the Chinese physics community, and Shen Qichai can also guess that today's meeting at the Academy of Sciences must be related to physics.

The rain became heavier and heavier, and the man next to Academician Pan stretched out a black umbrella to shield Academician Pan from the rain, and the two entered the Academy of Sciences building.

"The man holding the umbrella for Academician Pan is a soldier, right? I have an impression of him, he has been on TV, and he is a very young general. Shen Qi has a keen eye, even if the person holding the umbrella is wearing civilian clothes, Shen Qi can catch the military aura from him, if he is not mistaken, he should be a major general who has just been appointed.

"Highly educated soldiers, technical generals. Let's go, Shen Qi, get out of the car, one day the generals will also hold umbrellas for you to cover the rain. Dean Ning said.

Dean Shen Qi and Ning entered a conference room in the Academy of Sciences building, which had no windows and was full of walls.

In order to make the atmosphere in the room not so oppressive, some green plants were placed in the conference room to create vitality.

Under the introduction of Dean Ning, Shen Qi and Academician Pan got to know each other: "Hello, Academician Pan, I have admired my name for a long time. ”

Half of Academician Pan's hair, who was worried about national affairs, turned white, and he shook hands with Shen Qi: "Sit down Shen Qi, the Chinese key, we need your key." ”

Idlers and others retreated, and the door of the conference room was closed.

Shen Qimo counts, one, two, three...... Eighty or ninety, there were ten people in the room, eight physicists, one mathematician with physics skills, and one soldier.

The nature of this academic exchange meeting is certainly unusual, four of the eight physicists are academicians, and the remaining four are also well-known scholars in the Chinese physics community.

"Dear colleagues, Chief Nie, let's go straight to today's topic. Academician Pan presided over today's academic exchange meeting, he did not talk nonsense, and began to state the PPT: "It has been a few years since the Micius was in the sky, and the quantum communication project on the ground is in full swing as planned, and it can be said that we are at the forefront of the world in the research and application in the field of quantum information." ”

Shen Qi was in awe, Academician Pan and his team were doing great things, real national events.

Glancing at the only soldier in the room, Shen Qi found that Chief Nie's eyes flashed with excitement, but there was also a hint of worry in the excitement.

Shen Qi does not understand military affairs, but he has basic military knowledge, modern warfare is an information war, once the war starts, if our communication system is cut off and monitored by the enemy, then it will still be a wool, and the blind and deaf will only be abused by blood.

"Compared with traditional keys, quantum keys are absolutely safe in nature, which ensures the reliability of the optical quantum communication system we built, but ......" Speaking of this, Academician Pan was a little frustrated, and also patted the desktop with some annoyance: "However, not long ago, our quantum secure communication project was hacked, and the origin of these hackers is unknown, but we have reason to believe that they are organizing and purposefully launching a tentative attack on us." ”

"Did the enemy succeed?" Shen Qi blurted out, his face solemn, and at the same time realized that this was a state secret!

"They didn't really succeed, but they opened the first security door that we carefully set up, which had to cause us to pay attention and be alert, and our system needs to be further improved. Professor Shen, the reason why I invite you to come here today is to ask you to help us set the world's most secure security door password. Academician Pan looked at Shen Qi and placed high hopes on him.

"But what can I do in the field of quantum communication?" Shen Qi fell into deep thought.

"Shen Qi, Li Man's conjecture has been proven by you, it's been two years. Dean Ning interjected, and he said, "You are the one who knows the Riemann conjecture best, and the theoretical use of the Riemann conjecture. In the past two years, haven't you studied in depth what practical use the Riemann hypothesis has been proven?"

"This ...... Of course, there were ideas. Shen Qi said.

Academician Pan, Dean Ning, Chief Nie, and everyone's eyes focused on Shen Qi, waiting for Shen Qi to talk about his thoughts.

Shen Qi cleared his throat and said, "Using the product of two 100-bit primes, that is, a 200-bit number as the key, will make the RSA system very secure. But there's a danger that the methods mathematicians use to decompose large numbers are not as simple as the trial-and-error search methods we use when finding prime factors for 221. ”

"The proof of the Riemann conjecture, and the establishment of the prime distribution system of the Riemann zeta function, allow us to theoretically find a new, more secure way to set the key to ensure the security of the Internet. Of course, this is a double-edged sword, if hackers take the lead in mastering the application technology of the Riemann zeta function prime distribution system, the Internet will become extremely dangerous. ”

"Thankfully, I haven't found a hacker with a higher level of mathematics than me for the time being, and if the country needs it, I will try to be the first to complete the application of the Riemann Zeta function prime distribution system. But the problem is that quantum communication and quantum keys are different from traditional Internet systems, so I don't know what I can do?" said Shen Qi, spreading his hands.

Dean Ning: "Our Professor Shen, you are at the forefront of the world in mathematics, but in physics and computer science, you seem to be studying topics in the seventies and eighties?"

"This ......" Shen Qixin said what can I do, I rely on self-study in physics, and I have never been to the most cutting-edge physics laboratory. My physics instructor, Witten, spent all day talking to me about theories from 50 years ago, and he used two small balls and a spring to tell me that this is the universe, that this is what physics is all about, that this has been true for the past 100 years, and that will be true for the next 100 years.

"Shen Qi, have you paid attention to the latest research results published by New York University? Their team claims to have found a connection between the Riemann hypothesis and quantum physics. I distilled the core idea of NYU that a quantum chaotic system has all the primes as its components, and you know what that means? I think you should know what that means, and I read your "On Complexity" that you just published in PRL, and in this purely theoretical physics paper, Shen Qi you talk about chaotic systems. ”

Shen Qi stood up suddenly, and after being speechless for a long time, he suddenly came to his senses: "Academician Pan, Dean Ning, I understand what you mean, if the quantum chaotic system takes all the prime numbers as its components, then I should be able to derive a set of equations that stipulate the energy levels of the quantum chaotic system corresponding to the zero point of all zeta functions...... In this way, it will be possible to apply the Riemann zeta function prime distribution system in the field of quantum communication encryption. No hacker on earth can crack the key of the Riemann conjecture + quantum physics, and the most extreme possibility is that in the end, we may not even be able to crack it ourselves...... So it's absolutely safe in nature. ”
