Jinling Institute for Advanced Study, Institute of Semiconductors.
An old man with a dignified face stood in a spacious laboratory.
In addition to him, there was a group of high-ranking people standing behind him. Among them was Director Li, who was familiar with Lu Zhou, as well as a few other department heads.
Everyone's eyes were focused on the unique tubular device, as well as the man standing in front of the single-photon entanglement emitter. They were waiting for his next move.
Lu Zhou looked at the time on his watch and looked at the researcher standing in front of the computer. He nodded at him.
"You can start now."
"Okay."
The short conversation ended.
The researcher standing in front of the computer pressed a button.
Just like what Academician Xue saw, entangled photon pairs were emitted from the single-photon entanglement emitter at a super-high frequency, forming a stream of information composed of single-photon pairs. The signal light on the quantum repeater was lit up, and the signal was sent to the receiver hundreds of meters away from the laboratory.
At the same time, the traditional communication channel, which was parallel to the quantum communication channel, also released a huge amount of data at the receiver. A special decoding device decoded the data according to the received quantum key.
The entire process involved extremely complex physics and information science principles, but for the people standing next to the equipment, it only took a second.
Other than the experts from the Chinese Academy of Sciences who were watching in front of the computer, the ministerial leaders standing behind the old man didn't even realize that the experiment was over.
It wasn't until Lu Zhou reminded them that the experiment was a success that their faces were filled with shock and confusion.
Director Li was the first to snap back to reality. He quickly walked to the group of experts and spoke.
"The experiment was successful?"
Academician Gao Junwen from the Institute of Information Engineering blinked his eyes. He exchanged a surprised look with his old friend next to him, then looked at Director Li and nodded.
"There's no doubt it is … Transmitter A sends a 'hello' through the traditional channel and the quantum channel.
'World' and the corresponding quantum key. As far as the result is concerned, without the key, even with our most advanced supercomputer, it is impossible to decode these two words. "
"Therefore, we can assume that even if the attacker has unlimited computing resources, they still cannot break our password system … There is no doubt that this is the unconditional secure communication technology we are looking for."
Academician Gao Junwen expressed the excitement in his heart. He looked like he couldn't tell if this was a dream or reality. He spoke in amazement.
"… I didn't expect to see such a perfect system in my lifetime."
"It's like a dream."
When Academician Gao said these words, he didn't deliberately control his volume.
Director Li wasn't the only one who heard it.
The old man standing not far away and the ministerial officials behind him also heard these words, and the expressions on their faces were replaced by astonishment at the same time.
After a long while, the old man spoke.
"This is quantum communication technology?"
"Yes." Lu Zhou nodded and said, "As Academician Gao said, theoretically, no one can intercept the information that passes through this channel. For medium and long-distance communication, our technology will be absolutely safe and reliable. "
The old man nodded, but he quickly thought of something, so he immediately asked, "What if someone controls the repeater? For example … deploying a nuclear submarine in the Pacific Ocean. "
Lu Zhou shook his head and said, "It's useless. The only thing a nuclear submarine can do is to destroy the quantum repeater or cut the quantum optical fiber. Once the channel is destroyed, once the quantum key is stopped, the data transmitted through the traditional optical fiber will also become invalid and become invalid information that can never be decrypted. "
A complete quantum key was not represented by a single entangled photon pair. When one of the entangled photon pairs collapsed due to being observed, it could not reach the next "checkpoint", and the subsequent signal would also be interrupted.
In the face of such a communication technology, the information sent was theoretically absolutely safe, unless someone could observe the entangled photon pairs without causing the exploration to collapse.
However, from the perspective of physics, this was simply impossible to achieve.
At least, it was impossible for the physics of Earth's civilization.
The old man looked at the uniquely shaped device in front of him. He went silent for a long time and suddenly spoke with emotion.
"It's like magic."
Lu Zhou smiled and said, "If you only look at the results, any scientific research results can be included in the category of magic, especially when they are first discovered."
The old man looked at Lu Zhou and spoke in a solemn manner.
"Information security has always been the most important difficulty we have encountered in the industrial information transformation. Including quantum computers and quantum communication technology … The impact of this on our society is no less than controllable fusion. "
"I have to thank you on behalf of the entire country."
Lu Zhou nodded and spoke politely.
"You're welcome.
"It is also my honor to be able to witness this moment."
…
Beijing.
Xicheng District Financial Street.
A man in a suit stood at the door. He reached out his hand and adjusted his tie. He then walked into the building with his head held high.
His name was Tony Azoff, and he was a manager from the American company SubCom.
SubCom, Japan's NEC, and Europe's Alcatel-Lucent were the giants in the global submarine optical cable business. They monopolized more than 90% of the global submarine optical cable market.
As for why he was standing there …
Naturally, it was because he had smelled Franklin's scent …
"Can you help me contact CEO Wang? I have an appointment. "
Azov spoke in fluent Mandarin and gave the receptionist a smile that he thought was confident and charming.
"Please wait a second, I'll contact him for you."
After waiting patiently for half a minute, a man who looked like a secretary walked out of the elevator.
"You are Mr. Azoff, right? CEO Wang is waiting for you in the conference room, please come with me."
The secretary made an inviting gesture and took him to the elevator. They went all the way to the conference room on the second floor.
When he arrived at the conference room, a slightly chubby middle-aged man stood up from the conference table and extended his right hand to him with a smile.
"Welcome to China, Mr. Azoff. You're here for the No. 3 Asia-Pacific submarine optical cable project, right? Thank you for your hard work! "
"Thank you." Azoff sat down at the conference table and took out the documents from his business bag. He looked at CEO Wang and smiled. "Since you already know, let's begin."
With the increasing demand for trans-Pacific communication, the original Asia-Pacific submarine optical cable line was a bit stretched. The construction of the Asia-Pacific submarine optical cable 3 (APCN3) had become an urgent matter.
Before he came to China, the telecommunications departments of South Korea, Japan, and Malaysia had already reached a preliminary cooperation intent. They planned to set up a committee with personnel from many countries to build the APCN3.
The main reason why he went to China on a business trip was to promote China's participation in this project and to promote their submarine optical cable business to the three giants in the China telecommunications industry.
After all, whether it was China, the United States, or other countries in the Asia-Pacific region, they all had an urgent need for this submarine optical cable. Azoff couldn't think of any reason for China to refuse.
For him, the only problem was how to skillfully use the art of negotiation, using the landing site and communication requirements as bargaining chips to make their potential customers pay more for their submarine optical cable.
The negotiation went very smoothly.
For telecommunications companies, submarine optical cables were just what they needed, and they had very few choices. Azov didn't have to spend much time talking before he successfully made CEO Wang look like he was interested.
However, at this moment, his phone suddenly vibrated.
CEO Wang looked at the caller ID on his phone screen and had an awkward expression on his face. Even though he didn't want to interrupt the meeting, he couldn't hang up on this call.
"Sorry, I have to take this call." CEO Wang made an apologetic expression to the manager of SubCom and stood up from the conference table.
"It's fine, I can wait."
Azoff looked at the China man leave the office. He wasn't in a hurry. He picked up the coffee on the table and took a sip. He then quietly waited.
Time slowly passed by.
Azoff, who was previously quite patient, couldn't help but frown.
He originally thought that this call would end soon, but he didn't expect that after ten minutes, there would still be no movement outside.
Just as he was wondering if he should go out and look at his watch for the fourth time, the door of the conference room finally opened. CEO Wang walked in.
However, this time, he had a dignified expression on his face.
It was precisely this trace of seriousness that was completely different from before that caused Azov to feel slightly uneasy.
Sure enough, as if to confirm his guess, CEO Wang spoke in an apologetic tone.
"Sorry, regarding the No. 3 Asia-Pacific submarine optical cable project … We are not interested."
Azoff's eyes suddenly widened, and he almost stood up from his chair.
"Wait a minute, what do you mean you are not interested?"
"I'm really sorry, I meant what I said." CEO Wang maintained an apologetic expression, but he had no intention of changing his mind. He said, "We have no plans to add submarine optical cables for the time being, at least not now. Why don't you leave your phone number? If we change our mind, we'll contact you. "
Azoff nearly vomited blood when he heard this.
What do you mean we'll contact you if we change our mind?
I even brought the contract!
Today, he came here with the intention of making a deal, or at least signing a letter of intent!
"I sincerely suggest that you reconsider! Based on the current growth rate of communication bandwidth demand, just the No. 2 submarine optical cable won't be able to meet the needs of the Asia- Pacific region's information development! "
CEO Wang, who was sitting across from Azoff, nodded and spoke without any change in expression.
"We'll consider it."
The meeting ended just like that.
After that, Azoff continued to visit Unicom, Mobile, and the other two communication giants in China. However, the response he received was almost the same.
It was even worse than what he had experienced at Unicom. The other two didn't even have the intention to discuss this issue with him, and they sent him away in less than five minutes.
His intuition told him that it was all because of that phone call.
However, he didn't understand what kind of phone call had such great power to turn a good situation into such a situation.
When Azoff finally came out of the headquarters of Unicom, he was in a state of confusion. The relaxed expression on his face had completely disappeared.
Could it be that NEC or Alcatel-Lucent stole their business?
But it didn't seem like it.
Right now, he was only worried about one thing. How should he write this report so that he could report the truth, and at the same time, make the three consecutive negotiations seem less embarrassing …
