Chapter 1192

Institute of semiconductors, Jinling Institute of higher learning.

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

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

"It's time to start."

"OK."

Two short sentences ended.

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

Almost the same scene that academician Xue saw at the beginning, the entangled photon pair shoots out from the single photon entanglement transmitter at an ultra-high frequency, forming a channel of information flow composed of single photon pair, lighting up the signal lamp on the quantum repeater, and being amplified and sent to the receiver hundreds of meters away from the laboratory.

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

The whole process contains extremely complex physics and informatics principles, but for people standing next to the whole set of equipment, it is only a moment.

In addition to the shocked and surprised expressions of the experts of the Chinese Academy of Sciences standing around the computer, the ministerial leaders standing behind the old people didn't even realize that the experiment was over.

Until Lu Zhou reminded them that the experiment had been successful, their faces were dazed and shocked.

First back to God, director Li quickly walked to the side of the group of experts and confirmed.

"The experiment was successful?"

Academician Gao Junwen from the Institute of information engineering blinked his eyes, then exchanged a surprised look with his old friend, and then looked at director Li and nodded his head.

"No doubt it is A transmitter sends a sentence of "Hello world" and corresponding quantum key through traditional channel and quantum channel respectively. As a result, it is impossible to decode these two words without knowing the key, even with our most advanced supercomputing. "

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

He used two sentences to express his excitement. The expression on academician Gao Junwen's face was like he couldn't tell whether it was a dream or a reality. He said in a dreamy way.

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

"It's like a dream."

In saying these words, academician Gao did not deliberately control his own volume.

After a long time, the old man said.

"This is quantum communication technology?"

"Yes," Lu Zhou said, nodding his head, in the most popular way possible, "as academician Gao said, in theory, no one can intercept the information passing through this channel. For medium and long distance communication, our technology will be absolutely safe and reliable. "

The old man nodded, but soon thought of something, and immediately asked, "what if someone controls the repeater? For example A nuclear submarine is deployed in the upper Pacific. "

Lu zhoushook his head: "no use, the only thing a nuclear submarine can do is destroy the quantum repeater or cut off the quantum fiber. When the channel is destroyed, once the quantum key is stopped from being distributed, the data transmitted through the traditional optical fiber will also be invalid and become 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 photon pairs collapses due to observation and cannot reach the next "checkpoint", the subsequent signal will be interrupted.

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

However, from the point of view of physics, this is impossible.

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

Looking at the unique equipment in front of him, the old man was silent for a long time, and suddenly said with heartfelt emotion.

"It's like magic."

Hearing this metaphor, Lu Zhou smiled and said: "if we only look at the results, any scientific research results can be included in the category of magic, especially when they are just discovered."

Facing the boat, the old man said solemnly.

"Information security has always been the most important difficulty we encounter in the transformation of industrial informatization, or even none of them. Including quantum computers, there are also quantum communication technologies I'm afraid the impact on our society is no less than controllable fusion. "

"I have to thank you for the people of the country."

The boat nodded a little, politely.

"You're welcome.""It's also my pleasure to witness this moment."

……

Go to Beijing.

Financial Street, Xicheng District.

A man in a suit stood at the door, reached for his necktie and walked into the building.

His name is Tony Azov, and he is the manager of Subcom in the United States.

As a giant of the global submarine cable business, Subcom, NEC of Japan and Alcatel lucent of Europe monopolize more than 90% of the global submarine cable market share.

As for why he stands here.

That's because of the smell of Franklin

"Can you contact your president Wang for me? I have an appointment. "

Speaking in fluent Chinese, Azov showed a self-confident and charming smile to the front desk mm.

"Just a moment, please. I'll get in touch for you."

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

"You are Mr. Azov, aren't you? Mr. Wang is waiting for you in the conference room. Please follow me."

With that, the secretary made a gesture of invitation, took him to the elevator, and all the way to the meeting room on the second floor.

When he arrived at the meeting room, a middle-aged man dressed in a slightly fat look stood up from the meeting table and smiled and held out his right hand to him.

"Welcome to China, Mr. Azov. Are you here for the 3rd Asia Pacific submarine cable project? It's been a hard journey! "

"Thank you," he said with a smile. "Now that you know that, let's start."

With the increasing demand of transpacific communication, the original Asia Pacific submarine cable line has appeared to be in short supply. The construction of Asia Pacific submarine cable 3 (apcn3) has become an urgent matter.

Long before he came to China, the communication departments of South Korea, Japan, Malaysia and other countries had reached an initial intention of cooperation, and intended to establish a committee of multinational personnel to build the apcn3.

The main task of his business trip to China is to promote China's participation in the project and promote their submarine optical cable business to the three giants of China's communication 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, and Azov can not think of any reason why China may refuse it.

Now for him, the problem is just how to skillfully use the art of negotiation, using landing sites and communication needs as chips to make their potential customers pay more costs to pay for their submarine cable.

The negotiations went very well.

For communication companies, submarine optical cable is just needed, and their choices are relatively few. It took almost no words to make Mr. Wang's face move.

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

Looking at the call display on the mobile phone screen, Mr. Wang's face showed a bit of embarrassment. Although he didn't want to interrupt the meeting, he couldn't hang up.

"Sorry, I'll take a call." With an apologetic expression to the manager of Subcom, Mr. Wang stood up from the meeting table.

"It's OK. I can wait."

Looking at the Chinese who left the office, he took a sip of coffee from the table and waited quietly.

Time passes by minute by second.

At the same time, he could not help frowning.

Originally, he thought the call would be over soon, but he didn't expect there was any movement outside after ten minutes.

Just as he was wondering if he was going to go out and have a look at his watch for the fourth time, the door of the conference room finally opened, and the general manager Wang came from the outside.

But this time, his face seemed to be a little dignified.

It was this very different dignification that made Azov feel a little uneasy.

Sure enough, as if to confirm his conjecture, said the king in an apologetic tone.

"I'm sorry about this 3 Asia Pacific undersea cable project We are not interested. "

Azov's eyes were suddenly round and he almost didn't get up from the chair.

"Wait, what do you mean you're not interested?"

"I'm really sorry, literally," he said with an apologetic expression. However, Wang always had no intention of changing his mind. He continued, "we have no intention of adding undersea cable at present, at least not at present. If we change our mind, we will contact you. "Hearing this, Azov almost didn't spit blood.

What is to change your mind and contact again?

He even has the contract!

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

"I sincerely suggest that you reconsider! According to the current growth rate of communication bandwidth demand, only the Asia Pacific undersea optical cable line 2 is unable to meet the needs of information development in the Asia Pacific region! "

Wang, who was sitting opposite to Azov, nodded his head and said with no change in expression.

"We'll think about it."

So the talks ended.

Later, he continued to visit China Unicom and China Mobile, and visited two other communication giants in China. However, he received almost the same response.

Even worse than his experience in Telecom, the latter two didn't plan to discuss the issue with him at all, or even dismissed them in five minutes.

Intuition told him that it was all because of the phone.

However, he didn't understand what kind of phone call it was. It had so much energy that it turned all the good situation into what it is now.

When he finally came out of the mobile headquarters building, he was in a dazed state. At first, his easy expression was gone.

Did NEC or Alcatel lucent steal their business?

But it doesn't seem like much.

He is only worried about one thing now. How to write this report in the end can not only truthfully report things up, but also make the three negotiations lose in a row, which seems less humiliating
