Scholar’s Advanced Technological System

Perhaps it is a little embarrassing to know that my request has been made. Director Li has just said this, and the voice is getting smaller and smaller.

However, the small volume does not make this difficult request sound more euphemistic, so he finally stunned Lu Zhou with a blank eye.

"The words I just mentioned are telling you where the key to solving the problem is, not letting you continue to ask me how to solve the problem!"

However, in the face of Lu Zhou's spit, Li did not have any introspection, but instead continued to say with a cheeky face.

"This... Anyway, you have found the problem, can you solve it?"

Looking at the embarrassed smile on Director Li's face, Lu Zhou could not help but create an illusion.

Does this guy think of himself as a small jingle?

No, it may not be an illusion.

Eight achievements are like this...

......

With the phrase "I will think about it when I have time," I finally sent away Li, and I saw Lu Zhou, who had almost the same time, called Wang Peng, and then went straight to the parking lot.

Sitting in a black car, watching Wang Peng drive the car on the road, sitting in the back row of the boat suddenly said.

"Wang Peng."

"what's up?"

Lu Zhou thought about it and said.

“What is science in your opinion?”

For Lu Zhou, who occasionally asks himself some strange questions, Wang Peng is considered to be accustomed to it.

Thinking for a while, he said.

"I think it should be the way to solve the problem, probably similar"

“It’s similar to letting the water burn, let the air solidify, let the steel fly... does that mean?”

Wang Peng thought for a moment, although he felt that this statement was a bit abstract, but he felt that there was nothing wrong with it, so he nodded.

"more or less."

Upon hearing this unexpected answer, Lu Zhou sighed softly.

"So, this is the biggest misunderstanding of science."

Wang Peng: "...?"

Lu Zhou: "Go to the Jinling Institute of Advanced Studies."

Wang Peng asked the endoscope of the car.

"It doesn't matter at the three o'clock meeting?"

"I will call Chen Yushan a little while in a while," Lu Zhou thought and said, "She goes the same."

......

Due to the interaction between the quantum communication system and the channel, the coherence of the pure state in the system is attenuated, so that the randomness of the internal phase difference of each superimposed component is increased, resulting in failure of quantum information transmission.

A more friendly solution is to add a repeater at a distance from the traditional means of communication, and amplify the attenuated signal to continue transmitting.

However, this method seems to sound very easy, but for quantum communication means, it is difficult to go to heaven. Because quantum communication is mainly based on the quantum effect of the single photon spin state, the amplifying optics destroys the qubit.

At present, there are two types of relay technologies, one is trusted relay, and the other is quantum relay.

The former is similar to a key relay, allowing keys to pass between trusted workstations. Relative to the latter, the technical difficulty is slightly lower, but the problem is that once the relay station is controlled by hostile forces, there is a possibility of eavesdropping.

In other words, with this technical route, unconditional security is based on the premise of “workstation credibility”.

The latter, based on quantum entanglement distribution technology, establishes shared entanglement pairs between adjacent sites, stores entangled pairs by quantum storage technology, and applies entanglement conversion operations to achieve shared entanglement between adjacent sites.

In terms of security, the latter is naturally unparalleled, but the price is that the technical difficulty is quite large, and it is so big that there is no friend. Before and after 07, the academic circles gave up.

Objectively speaking, if it is only the communication within the country, for example, as a military special line, the use of trusted relay is completely sufficient. Just like the "Beijing-Shanghai trunk line" and the Mozi number, under the protection of the people's army, there is no possibility that the workstations will be "occupied".

However, when the communication scope is expanded to a global scale, the security of the overseas site cannot be 100% credible, and the security of the trusted relay remains to be discussed.

In the current situation of information globalization, no country can break away from the big collective of the Internet. What Li Director expects is obviously not the kind of technology that can only be closed to the door.

Therefore, the key to the problem is how to solve the bottleneck of the quantum repeater.

When I arrived at the Jinling Institute of Advanced Studies, Lu Zhou and Chen Yushan called and entrusted her to the afternoon meeting, and edited an email to send the outline of the meeting to her mailbox.

The main discussion of the meeting was the work arrangement of the lunar surface quality accelerator project. In the case that he had already arranged the work in advance, he did not necessarily have to come out personally.

In contrast, there are more important things waiting for him to do.

When I came to the underground research institute, Lu Zhou went to the lab where the carbon-based quantum processor chip was researched some time ago, and looked at the carbon-based integrated circuit board packaged in a transparent container, saying to himself.

"I was originally planning to get the project to study the project again."

"Well, let's try it first."

Say, Lu Zhou indicated that Xiao Ai evacuated the inert gas in the transparent container, unlocked the lock, and put on a special glove to take the well-preserved carbon-based integrated circuit board out of it.

The difficulties of quantum repeaters can be divided into three parts, entanglement exchange, entanglement purification, and quantum storage.

The first two are still good to say, as for the last one, basically the quantum computer is in the same dimension.

Interestingly, however, the study of quantum memory and quantum computers has some overlap. The only difference is that quantum memory is almost indispensable for long-distance quantum communication, but not for quantum computers.

If you can, you can make a more advanced quantum computer. If you don't have it, there are also less advanced quantum computers to choose from... that is, the one he himself diy.

In fact, the reason why Lu Zhou did not study the quantum memory technology at the time was more than 80% of the reasons for this factor.

In his original idea, with the breakthrough of quantum computer technology and its widespread application in the commercial field, capital will naturally push quantum memory technology forward to seek to build faster and more powerful quantum computers.

At that time, he didn't have to spend too much effort, and he didn't need to waste precious points. Naturally, he could get the quantum memory technology he expected.

"Quantum entanglement between systems stored in memory and any remote systems not in memory must be maintained throughout the storage time..."

"If this entanglement is destroyed at any time, such as collapse due to observations, then the device can no longer function as a quantum memory, but instead becomes an 'entangled interrupt channel' that can only transmit classic information."

"It's a little hard to do..."

Looking at the integrated circuit board lying on the experimental equipment, Lu Zhou pondered for a long time.

It was not until the minute hand passed a large space that he suddenly thought of something, and said.

"This is not a topic that one can accomplish."

"but……"

"I really don't think it's an average person."

Xiao Ai: [(??????)]

Speaking to himself, Lu Zhou, sitting at the experimental table, suddenly picked up the ballpoint pen and wrote a line on the draft paper.

[3D Quantum Memory]

Looking at the seven neat characters on the paper, Lu Zhou nodded with satisfaction.

"For the time being, please call this name first!"
