Scholar’s Advanced Technological System

Institute of Semiconductors, Jinling Institute of Advanced Studies.

In the spacious laboratory, stood a majestic old man.

In addition to him, there is a circle of people who are obviously not low behind him. Among them, Director Li, who is more familiar with Lu Zhou, also has several departments that are nodding their heads.

At this moment, everyone's eyes are condensed on the uniquely shaped circular tubular device, and the man standing on the back of the single photon entanglement transmitter, waiting for his next move.

Looking at the time on the watch, Lu Zhou turned his eyes to the researcher standing in front of the computer and nodded to him.

"You can start."

"Ok."

Two short conversations ended.

The researcher standing in front of the computer pressed the button.

Almost as the scene that Xue Academician saw at the beginning, the entangled photons were emitted from a single-photon entangled emitter at an ultra-high frequency, forming a stream of information consisting of a single photon pair, and a signal light on the quantum repeater. It lights up and is amplified and transmitted to a receiver hundreds of meters away from the laboratory.

At the same time, the traditional communication channel parallel to the quantum communication channel also releases huge data at the receiving end, which is decoded by a special decoding device according to the received quantum key.

The whole process contains extremely complicated principles of physics and informatics, but for those who stand next to the whole set of equipment, it is only a matter of moments.

In addition to the shocking and weird expressions of the Chinese Academy of Sciences experts sitting in front of the computer, the ministers who stood behind the old man did not even realize that the experiment was over.

It was not until Lu Zhou reminded them that the experiment had been successful, and their faces showed a sense of sorrow and horror.

When I first came back to God, Director Li quickly walked to the side of the group of experts and confirmed with enthusiasm.

“Is the experiment successful?”

Academician Gao Junwen from the Institute of Information Engineering squinted his face, then exchanged a strange look with the old friend next to him, and then looked at Director Li and nodded.

"There is no doubt... a transmitter sends a 'helloworld' and a corresponding quantum key through the traditional channel and the quantum channel. As a result, even if we don't master the key, we use our most advanced. It is impossible to decode these two words.

"So we can assume that even if the attacker has unlimited computing resources, it still cannot decipher our cryptosystem... no doubt this is the unconditional secure communication technology we are looking for."

Connected with two sentences without any doubt to express the excitement of the heart, the expression on the face of Academician Gao Junwen is like it is not clear whether this is a dream or a reality, and the nightmare sighs.

"...I didn't expect to see such a perfect system in my lifetime."

“It’s like dreaming.”

When he said these words, the high academician did not deliberately control his own volume.

It’s not just that Director Li heard it.

The old man not far away, as well as the ministerial officials standing behind him, also heard this, and the expression on his face was replaced by the shock of the same.

After a long time, the old man opened his mouth.

“This is quantum communication technology?”

"Yes," Lu Zhou nodded, speaking in the most popular way. "As the High Academician said, no one can theoretically intercept the information passed through this channel. For the medium and long distance communication. Our technology will be absolutely safe and reliable."

The old man nodded, but quickly thought of something, so he immediately asked: "If someone controls the repeater? For example... deploy a nuclear submarine in the Pacific."

Lu Zhou shook his head: "It's useless. The only thing a nuclear submarine can do is to destroy the quantum repeater or cut the quantum fiber. When the channel is destroyed, once the quantum key is stopped, the data transmitted through the traditional fiber will also fail. , becomes invalid information that can never be decrypted."

A complete quantum key is not represented by a single entangled photon pair. When one of the entangled photons collapses because it is observed, it cannot reach the next "checkpoint" and subsequent signals are interrupted.

In the face of such communication technologies, the information transmitted is theoretically absolutely safe, unless someone can observe the entangled photon pair without causing exploration collapse.

However, from a physics point of view, this is simply impossible.

At least, it is impossible for the physics of earth civilization.

Looking at the uniquely shaped equipment in front of me, the old man was silent for a long time, and suddenly he said with a heartfelt feeling.

"It's like magic."

Hearing this metaphor, Lu Zhou smiled and said: "If you only look at the results, any scientific research results can be included in the magic, especially when they have just been discovered."

Facing Lu Zhou, the old man said solemnly.

"Information security has always been one of the most important difficulties we encountered in the transformation of industrial information. There is not even one of them. Quantum computers, including quantum computers... This is as much impact on our society as it is. Control fusion."

"I have to say thank you to the people of the whole country."

Lu Zhou nodded slightly and said politely.

"You're welcome."

"It is also my honor to be able to witness this moment."

......

Going to Beijing.

Xicheng District Financial Street.

A man in a suit and a suit stood at the door, reached out to take care of the neckline tie, and swung in and walked into the building.

His name is Tony Azoff, a manager from a US subsidiary.

As the global submarine cable business giant, sub and Japanese nec, Europe Alcatel-Lucent three companies, monopolize more than 90% of the world's submarine cable market share.

As for why he is standing here.

Naturally because I smell the flavor of Franklin...

"Can you contact me with your general manager? I have an appointment."

Speaking in fluent Chinese, Azoff showed a smile that he thought was confident and charming to the front desk mm.

"Please wait a moment, I will contact you."

After waiting patiently for half a minute, a man who looked like a secretary soon came in the direction of the elevator.

"You are Mr. Azov, yes, Mr. Wang is waiting for you in the conference room, please come with me."

After that, the secretary made a gesture of asking, took him to the elevator, and went all the way to the conference room on the second floor.

When he arrived at the conference room, a middle-aged man dressed in a slightly blessed figure stood up from the conference table and smiled and extended his right hand to him.

"Welcome to China, Mr. Azov. Are you coming for the Asia-Pacific submarine cable project on the 3rd? It has been hard work!"

"Thank you," sat down at the conference table. Azov took out the documents in the business bag that he carried with him and spread it on the table. He looked at the same person who sat down on the opposite side. He smiled and said, "Since you have If you understand it, let's get started."

With the growing demand for trans-Pacific communications, the original Asia-Pacific submarine cable line has become somewhat stretched, and the construction of Asia-Pacific submarine cable No. 3 (apcn3) has become an urgent matter.

Long before he came to China, the communications departments of South Korea, Japan, Malay and other countries had reached a preliminary cooperation intention, and planned to set up a committee appointed by many countries to build this apcn3.

The main task of his trip to China this time is to promote Huaguo to participate in this project and to promote their submarine cable business to the three giants of the Chinese communications industry.

After all, whether it is China or the United States, or other countries in the Asia-Pacific region, there is an urgent need for this submarine cable. Azov simply cannot think of any reason why China may refuse.

For him now, the problem is simply how to skillfully use the art of negotiation, using landing sites and communication needs as a bargaining chip, allowing their potential customers to pay more to pay for their submarine cable.

The negotiations went very smoothly.

For the communications company, the submarine cable is just needed, and their choice is relatively small, Azov almost did not spend much tongue to succeed in making this Wang’s face with an expression of emotion.

However, at this moment, the sound of the phone vibration suddenly rang.

Looking at the caller ID on the screen of the mobile phone, Wang’s face showed a distressed expression. Although he didn't really want to interrupt the meeting, this call is not something he can hang up.

"Sorry, I took a call." I made a sorry expression to the manager of the sub company. Mr. Wang stood up from the conference table.

"Nothing, I can wait."

Looking at the Chinese who left the office, Azov was not in a hurry. He took a sip of the coffee on the table and waited quietly.

Time passes by one minute.

Azov, who had been patient before, couldn't help but frown.

Originally, he thought that the call would soon end, and he did not expect that there was no movement outside for ten minutes.

Just as he wondered if he was going out to look at it, and when he watched the watch for the fourth time, the door of the conference room was finally opened, and the king always walked from the outside.

Only, this time his face, his expression seems to be a little dignified.

It was also this condensed dignity that was completely different from the previous one, which made Azov feel a little uneasy.

Sure enough, as if confirming his guess, the king always said with apologetic tone.

"Sorry, about this No. 3 Asia-Pacific submarine cable project... we are not interested."

Azov’s eyes suddenly rounded up and almost didn’t stand up from the chair.

"Wait, what does it mean to be uninterested?"

"I am sorry, it is literal," he said with apologetic expression. However, the general manager did not intend to change his mind. He continued, "We have no plans to add submarine cables for the time being, at least not now. If you want to stay Let's call, if we change our mind, we will contact you."

Hearing this sentence, Azov almost did not vomit blood.

What is the change of idea and then contact?

He even brought the contract together!

Today he came here with the purpose of holding a deal or at least signing a letter of intent for cooperation!

"I sincerely suggest that you rethink it! According to the current growth of communication bandwidth demand, only the Asia-Pacific submarine cable No. 2 line can not meet the needs of information development in the Asia-Pacific region!"

Sitting in the opposite side of Azov, Wang always nodded and said that there was no change in his expression.

"We will consider it."

The talks ended like this.

Later, Azov went on to China Unicom and moved there, and visited two other communication giants in the country. However, the answers were almost exactly the same.

Even worse than his experience in telecommunications, the latter two did not plan to discuss this issue with him, and even sent them away in five minutes.

Intuition tells him that everything is because of that phone.

However, he did not understand what the phone was, and there was such a great energy that it turned all the good things into what it is now.

When I finally came out of the mobile headquarters building, Azov’s whole person was in a state of arrogance. At first, the expression on his face was gone.

Is nec or Alcatel-Lucent stealing their business?

But it doesn't seem like it.

He is only worried about one thing now. How to write this report in order to report things truthfully and make the three-game losing streak seem less shameful...
