Shen Qi was walking on the Yan University campus, and the sky was drizzling.

A black car drove to Shen Qi and stopped. The rear window opened and there was a person sitting in the back row. He waved to Shen Qi: "Shen Qi, get in the car."

"Director 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.

"Let's talk about getting in the car." Dean Ning pushed open the door in the car and couldn't wait to greet Shen Qi getting in.

Shen Qi got into the car and started to leave Yanda.

"You have been back in China for almost a month this time. When will you return to Princeton?" asked Dean Ning.

Shen Qi said: "The plan is to go back to Princeton next week, and you can also adjust it appropriately according to the actual situation. It's nothing to leave a few weeks later."

"There is no need to postpone the original plan, otherwise the United States may have doubts," said Dean Ning.

"Director Ning, where are we going?" Shen Qi had a premonition from Dean Ning's serious expression and tone. Is this going to cause trouble?

"Go to the Academy of Sciences for a meeting, it's almost here."

The car soon arrived at the gate of the Academy of Sciences. Shen Qi was about to get off the car and found two people outside the car who looked unusual.

One of them wore glasses and exuded a wise atmosphere. He is famous in the Chinese physics community and is the chief scientist of China's quantum satellite project.

"Academician Pan is here to have a meeting?" Shen Qi was a little surprised. Academician Pan is famous for breaking the world record in the international physics community. Academician Pan's team recently achieved 18 qubit entanglements, setting a new world record again.

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

Academician Pan and President Ning are both big shots in the Chinese physics industry. Shen Qi can guess that today's meeting at the Academy of Sciences must be related to physics.

The rain was getting heavier and heavier. The man next to Academician Pan opened a black umbrella to hide the rain from Academician Pan. The two entered the Academy of Sciences building.

"The person who holds an umbrella for Academician Pan is a soldier? I have an impression of him. He has been on TV and is a very young general." Shen Qi's eyes were keen. Even if the person holding an umbrella was wearing casual clothes, Shen Qi could capture the atmosphere of a soldier from him. If he remembers correctly, he should be a major general who had just been appointed.

"A highly educated soldier, technical general. Let's go, Shen Qi, get off the car, and one day the generals will hold an umbrella for you to hide the rain." said Dean Ning.

President Shen Qi and Dean Ning entered a conference room in the Academy of Sciences building. This conference room did not even have windows, all of which were walls.

In order to make the indoor atmosphere less depressing, some green plants are placed in the conference room to create vitality.

Under the introduction of President Ning, Shen Qi and Academician Pan got to know each other: "Hello, Academician Pan, I have long admired the name."

Academician Pan, who was worried about national affairs, had half of his hair turned white. He shook hands with Shen Qi: "Sit down Shen Qi, China's key, we need your key."

The idle people were waiting to retreat, and the door of the conference room was closed.

Shen Qimo counted, one, two, three...eighty or ninety, there were ten people in the room, eight physicists, a mathematician with a background in physics, and a soldier.

The nature of this academic exchange meeting is definitely 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, we will go directly to today's topic." Academician Pan presided over today's academic exchange meeting. He did not speak nonsense, and began to make a statement by operating the ppt: "There have been a few years since the Mozihao went to heaven. The quantum communication engineering on the ground is being carried out in full swing as planned. It can be said that we are at the forefront of the world in research and application in the field of quantum information."

Shen Qi was solemnly respectful that Academician Pan and his team were doing big things, real national affairs.

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

Shen Qi does not understand military affairs, but he has basic military knowledge. Modern warfare is an information warfare. Once a war starts, if our communication system is cut off by the enemy and monitored, then it will be yarn. The blind and deaf will only be tortured 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. However..." Speaking of this, Academician Pan was a little frustrated and a little annoyed to pat the desktop: "However, not long ago, our quantum confidential communication project was hacked, and the origin of these hackers is unknown, but we have reason to believe that they launched a tentative attack on us in an organized and purposeful manner."

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

"They did not really succeed, but they opened the first anti-theft door we carefully set up, which had to attract our attention and be alert. Our system needs to be further improved. Professor Shen, the reason why I invited you here today is to ask you to help us set the safest anti-theft door password in the world." Academician Pan looked at Shen Qi and placed high hopes.

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

"Shen Qi, you have proved the Riemann conjecture for two years." Dean Ning interrupted, and said: "You are the one who knows the Riemann conjecture best and the theoretical uses of the Riemann conjecture. In the past two years, have you not studied in depth what practical uses of the Riemann conjecture after it was proved?"

"This...of course I have had an idea." Shen Qi said.

Academician Pan, President Ning, and Chief Nie, 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-digit prime numbers, that is, a 200-digit number as the key, will make the a system very safe. But there is a danger that the method used by mathematicians to decompose large numbers is not the simple trial and error search method we use when we find the prime factor of 221."

"The proof of the Riemann conjecture and the establishment of the Riemann zeta function prime distribution system have allowed us to theoretically find a safer new way to set keys to ensure the security of the Internet. Of course, this is a double-edged sword. If the hacker first mastered the application technology of the Riemann zeta function prime distribution system, the Internet would become extremely dangerous."

"Thankfully, I have not found a hacker with a higher level of mathematics than me. If the country needs it, I will try to first complete the application technology setting 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?" Shen Qi spread his hands and said.

Dean Ning: "Our Professor Chen, you are at the forefront of the world in mathematics, but in physics and computer science, what you are studying is a topic from the 1970s and 1980s?"

"This..." Shen Qixin said, what can I do? I rely on self-study to make up for it. I have never been to the most cutting-edge physics laboratory. My physics instructor Weiteng, who discussed the theory from fifty years ago with me all day long, told me with two small balls and a spring experimental equipment that this is the universe, this is the whole of physics, this is the case in the past one hundred years, and the same is true for the next one hundred years.

Academician Pan said: "Shen Qi, have you paid attention to the latest research results published by New York University? Their team claimed that they have found the connection between the Riemann conjecture and quantum physics. I have extracted the core view of New York University that the quantum chaos system takes all prime numbers as its components. Do you know what this means? I think you should know what this means. I have read "On Complexity" you just published in PRL. In this purely theoretical material theory article, Shen Qi, you discussed the chaos system."

Shen Qi suddenly stood up and woke up after a long speechless sentence: "Academician Pan and President Ning, I understand what you mean. If the quantum chaos system takes all prime numbers as its components, then I should be able to deduce a set of equations that stipulate the energy level of the zero points of all zeta functions of the quantum chaos system... In this way, the Riemann zeta function prime distribution system will be possible to be implemented in the field of quantum communication encryption. No hacker on Earth can crack the Riemann conjecture + the key of quantum physics. The most extreme possibility is that in the end, even we ourselves may not be able to crack it... So it is essentially absolutely safe."
