Scholar’s Advanced Technological System

Perhaps knowing that his request is somewhat embarrassing, Director Li just said it, his voice becomes less and less unconscious.

Turning down the volume, however, did not make this difficult request sound more euphemistic, so he eventually caught a white-eyed eye on the ark.

“What I just said is to tell you where the key to solving the problem is, not to keep asking me how to solve it! ”

However, in the face of the canoe's spit, instead of reflecting on anything, Director Li continued with a thick face.

“This... anyway, you found the problem, why don't you just solve it? ”

Looking at Director Li's embarrassing smile on his face, the ark could not help but create an illusion.

This guy isn't treating himself like a tinkle bell.

No, it might not be an illusion.

Eight achievements are like this...

……

With a phrase, "I'll think about it when I have time." Finally, Director Li was sent off. After seeing the Ark boat, which was about the same time, he called Wang Peng and went straight to the parking lot.

On a black sedan, he watched Wang Peng drive the car on the road with a steering wheel, and suddenly the canoe in the rear row said.

“Wang Peng. ”

“What is it?”

The Ark thought about it and wanted to talk.

“In your opinion, what is science? ”

Wang Peng is also used to asking himself some strange questions occasionally.

After a while of serious reflection, he said.

“I think it should be the way to solve the problem, just like...”

“Similar to allowing water to burn, allowing air to solidify, allowing steel to fly… is that what you mean? ”

Wang Peng thought about it. Though he felt that the statement was a bit abstract, he felt that there seemed to be nothing wrong with it, so he nodded.

“Almost. ”

The ship sighed softly when it heard the unexpected answer.

“So this is the biggest misunderstanding of science. ”

Wang Peng: “…? ”

Ark: “Go to the Jinling Institute of Higher Studies. ”

Wang Peng looked at the car's endoscope and asked.

“Is the 3 o'clock meeting okay? ”

“I'll give the school--Chen Yushan a call,” Ark thought about it and said, “the same goes for her. ”

……

The interaction of the quantum communication system with the channel causes the cohesiveness decay of the pure state in the system, thus increasing the randomness of the internal phase differences of each superimposed component, leading to the failure of quantum information transmission.

A more friendly solution would be to add a repeater at a distance that would amplify the attenuated signal and continue sending, as is the case with traditional means of communication.

However, this approach may sound easy, but for quantum means of communication it is difficult to climb to the sky. Because quantum communication is primarily based on the quantum effect of a single-photon spin state, and amplifying the optics can destroy the quantum bits.

Currently, the relay technology is divided into two types: a trusted relay and a quantum relay.

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

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

The latter, on the other hand, is based on quantum entanglement distribution techniques to establish shared entanglement pairs between adjacent sites, to quantum storage techniques to entangle pair storage, and to apply entanglement conversion operations to achieve shared entanglement between adjacent sites.

In terms of safety, the latter is naturally unparalleled, but the cost is that technology is quite difficult, big enough to have no friends. Academics gave up once around 07 years ago.

Objectively, it would be entirely sufficient to use a credible relay if it were merely communications within the national territory, for example, as a dedicated military line. It is impossible, under the protection of the People's Army, to say that the workstation was “occupied”, as was the case with the Jinghu Main Line and the Mozi.

However, when communications reach global reach and the security of offshore sites is not 100 per cent credible, the security of credible trunks remains to be debated.

At a time of globalization of information, no country could be separated from the Internet as a large group, and it was clear that Li Bureau's long-term vision was not the kind of technology that had to close its doors to play with itself.

So the key to the problem is how to solve the bottlenecks in the quantum repeater.

Coming to the Jinling Institute of Higher Studies, Ark and Chen Yushan made a phone call, entrusted the afternoon meeting to her for processing, and edited an email and sent the conference outline to her mailbox.

The main discussion at the meeting was on the organization of the work of the Lunar Quality Accelerator project, which did not necessarily have to come out in person if he had already scheduled the work in advance.

In contrast, there are more important things to do.

He came to the underground research institute, and the ark went to the lab where he studied the carbon based quantum processor chip some time ago, looking at the carbon-based integrated circuit board enclosed in the transparent container, talking to himself.

“It was intended that the local month control project would be completed before the study of the subject. ”

“Well, let's try it first. ”

As he said, Ark indicated that Egg had emptied the inert gas in the transparent container and unlocked the code lock, putting on special gloves and removing the well-preserved carbon-based integrated circuit board from it.

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

As for the last two, basically the same dimension of the problem as the quantum computer.

Interestingly, however, quantum memory and quantum computer research have, to some extent, coincided. The difference is simply that quantum memory is almost essential for long-distance quantum communication, but not just for quantum computers.

There are more advanced quantum computers that can be built, and there are less advanced quantum computers that can be chosen… that is, the ones that he DIY himself comes out of.

In fact, more than 80 percent of the reasons why the Ark is not currently studying the technology of quantum memory is precisely due to this level of consideration.

In his original idea, as quantum computer technology breaks through and is widely applied in the commercial realm, capital naturally pushes quantum memory technology forward in search of faster, more processing quantum computers.

It doesn't take him too much energy, it doesn't take him to waste valuable points, and naturally he gets the quantum memory technology he expects.

“Quantum entanglement between a system stored in memory and any remote system not in memory must be maintained throughout the storage time...”

“If this entanglement is disrupted at any time, such as collapse due to observation, the device can no longer function as quantum memory, but becomes an 'entanglement interrupt channel' that can only transmit classical information. ”

“It's a little hard...”

With the integrated circuit board lying on the experimental equipment, the ark pondered for a long time.

It wasn't until the pin walked past a large grid that he suddenly thought of something like that, he said.

“This is not something a person can accomplish. ”

“But…”

“I don't think so. ”

Xiao Ai: [(? • ㅂ • ●)]

He muttered to himself, sitting on the ark 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 exact words on the paper, the ark nodded satisfactorily.

“Let's call it that first! ”
