Scholar’s Advanced Technological System

Jinling Institute of Advanced Studies Semiconductor Institute.

In a spacious lab, standing a dignified old man.

In addition to him, there is a clear circle of people behind him. Some of them are director Li, who is more familiar with Ark Boat, and some of the departments who just nodded their heads.

And at this moment, everyone's eyes are focused on that uniquely shaped circular tubular device, and on the back of the man standing on a single-photon entangled emitter, waiting for his next move.

Looking at the time on the watch, the ark nodded to the researcher standing in front of the computer.

“Here we go. ”

“Okay.”

Two brief exchanges are over.

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

Almost identical to the scene that Dr. Xue had initially seen, the entangled pairs of photons were emitted from the single-photon entangled emitters at an ultra-high frequency, forming an information flow consisting of single-photon pairs, lighting up the signal lights on the quantum repeaters and being emitted in amplification to receivers hundreds of metres away from the laboratory.

At the same time, traditional communication channels parallel to quantum communication channels also release huge amounts of data at the receiving end, which are decoded by specialized decoding devices based on the received quantum keys.

The whole process involves extremely complex physics and informatics, but for those standing next to the entire set of devices, it's just a matter of moments.

Apart from the shocking and surprising expressions of Chinese Academy of Sciences experts standing around in front of computers, the ministry leaders who stood behind the elderly did not even realize that the experiment was over.

It was not until the Ark reminded them that the experiment had been successful that their faces had revealed confusion and amazement.

First to return to God, Director Li quickly walked to the side of the group of experts and confirmed in a flash.

“The experiment worked? ”

Gao Junwen, an academician from the Institute of Information Engineering, blinked his face, then exchanged a surprising look with an old friend next to him, and then looked down at Director Li.

“Undoubtedly yes… the A launcher sends a sentence ‘HELLOWORLD’ and a corresponding quantum key through the traditional and quantum channels respectively. In terms of results, it is not possible to decode these two words without knowing the key, even using our most advanced overruns. ”

“So we can assume that even though an attacker has unlimited computing resources, he still can't decipher our password system… this is undoubtedly the unconditional secure communication technology we are looking for. ”

After using two sentences to unquestionably express the excitement in his heart, Gao Junwen's expression on his face was like he couldn't tell whether it was a dream or a reality, and he sighed like a dream.

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

“It's like a dream. ”

In saying these words, the High Academicians did not deliberately control their volume.

Not only did Director Lee hear it.

The old man, not far away, and the ministry officials standing behind him, heard the conversation, and the expression on his face was replaced by the same shock.

A long time later, the old man said.

“Is this quantum communication technology? ”

“Yes,” the ark nodded to the bottom, saying in the most general terms possible, "as the High Academician put it, no one is theoretically able to intercept the information passed through this channel. Our technology will be absolutely safe and reliable for medium and long distance communications. ”

The old man nodded, but quickly thought of something, and immediately asked, “What if someone controls the repeater? For example… deploying a nuclear submarine in the Pacific. ”

The ship shook its head: “No use, the only thing a nuclear submarine can do is destroy a quantum repeater or shear quantum optical fiber. If the channel breaks and the quantum key stops being distributed, the data transmitted through the traditional fiber optics will also fail and become invalid information that can never be decrypted. ”

A complete quantum key is not represented by a single entangled photon pair, and when one of the entangled photon pairs collapses as a result of being observed, the next “checkpoint” cannot be reached, and subsequent signals are interrupted.

In the face of such communication technologies, the information sent is theoretically absolutely secure unless one can observe entangled photon pairs without causing the collapse of exploration.

From a physical point of view, however, this is simply not possible.

At least not for the physics of Earth's civilization.

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

“It's like magic. ”

Hearing this metaphor, Ark Guan said with a smile: "If you look only at the results, any scientific results can be included in the magic category, especially when they are just discovered. ”

facing the ark, the old man spoke solemnly.

“Information security has been one of the most important difficulties, if not one, in the transformation of industrial informatization. There are also quantum communication technologies, including quantum computers… I'm afraid this has no less impact on our societies than controllable fusion. ”

“I have to say thank you on behalf of the people of the country. ”

The ark nodded slightly, politely.

“You're welcome. ”

“It is also an honor to witness this moment. ”

……

Shangjing.

Xicheng District Financial Street.

A man in a suit of leather shoes stood at the door, reached for the collar tie and walked wide into the building.

His name is Tony Azov and he is the manager of SubCom USA.

As a giant in the global submarine cable business, SubCom and Japan NEC and Europe Alcatrans have monopolized over 90% of the global submarine cable market share.

And why he's standing here.

That's naturally because I smell Franklin...

“Can you get in touch with your chief Wang? I have an appointment. ”

Speaking in fluent Chinese, Azov revealed a self-confident and charming smile to MM at the reception desk.

“Please wait, I'll be in touch for you. ”

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

“You are Mr. Azov, right, President Wang is waiting for you in the conference room, please follow me. ”

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

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

“Welcome to China, Mr. Azov. You're here for the Asia-Pacific submarine cable project, right? Good job on the way! ”

“Thank you," said Azov, sitting at the conference table, taking out the documents from the business bag he was carrying and spreading them on the table, looking across the street at President Wang, who also sat down, smiling. "Now that you understand, let's get started. ”

With the growing demand for trans-Pacific communications, the original Asia-Pacific submarine cable line has become somewhat overstretched, and the construction of the Asia-Pacific submarine cable 3 (APCN3) has become an urgent matter.

Long before his arrival in China, the communications departments of Korea, Japan, Malaysia and other countries had reached a preliminary cooperation intention to set up a committee composed of multinational delegates to build the APCN3.

The main task of his business trip to China was to promote China's participation in the project and to market their submarine optical cable business to the top three players in China's telecommunications industry.

After all, there is an urgent need for this submarine optical cable, whether in China or the United States, or in other countries in Asia and the Pacific, and Azov cannot think of any reason why the Chinese State might refuse.

For him now, the question was simply how to use the art of negotiation skilfully to leverage landing sites and communications needs to make their potential customers pay more for their submarine cables.

Negotiations went very smoothly.

For communications companies, submarine optical cables were just needed, and their options were relatively scarce, and Azov succeeded in displaying an unexpected look on the general face of Wang with little tongue.

At this point, however, the vibrating sound of the phone suddenly rang.

A glance at the call on the phone screen revealed a slightly embarrassing look on Wang's face. Although he didn't really want to interrupt the meeting, he couldn't hang up the phone either.

“I'm sorry, I have to take this.” He made an apology to the manager of SubCom, and President Wang stood up at the table.

“Nothing, I can wait. ”

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

Time goes by.

Azov, who had patience before, couldn't help but slightly frown.

He thought the call would be over soon, but he didn't think anything was going on outside for 10 minutes.

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

However, this time on his face, the expression seemed a little heavy.

It was this slightly different weight that made Azov feel a little uneasy.

Indeed, as if to corroborate his speculation, the king always spoke with apologies.

“Sorry about this Asia-Pacific submarine cable no. 3 project… we are not interested. ”

Azov's eyes suddenly glared and almost didn't get up from the chair.

“Wait, what do you mean you're not interested? ”

“I'm really sorry, that's literally what I meant," he said, maintaining his apologetic expression, but this President Wang had no intention of changing his mind, continuing, "We have no intention of adding submarine optical cables at this time, at least not now. Why don't you leave a call and we'll get back to you if we change our mind. ”

When I heard that, Azov barely threw up blood.

What do you mean change your mind?

He even got the contract!

He's here today with a deal - or at least a letter of intent!

“I sincerely suggest you reconsider! At the current rate of growth in communications bandwidth demand, it is only the Asia-Pacific submarine cable line 2, which simply cannot be adapted to the information development needs of the Asia-Pacific region! ”

Sitting across from Azov, Wang summed up and said with no change in expression.

“We'll think about it. ”

That concludes the talks.

Afterwards, Azov continued to connect and move there, visiting two other communications giants in China, but received almost identical responses.

Even worse than what happened to him at the telecom, the latter two had no intention of discussing the issue with him at all, and even sent them away in less than five minutes.

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

However, he did not understand what kind of telephone it was, it actually had so much energy to make all the good things look like this.

When he finally came out of the moving headquarters building, Azov's entire face was in a state of desolation, and at first the excess expression on his face had disappeared.

Did NEC or Alcatron steal their business?

But it doesn't look like much.

He's only worried about one thing right now. How can he write this report so that he can report it honestly and make the three negotiations look less embarrassing...
