Scholar’s Advanced Technological System

After coming out of the Jinling Institute of Higher Studies, Yanagi felt like a sleepwalker with a mess in his head.

After the physical demonstration, the ark went on to explain to them, at the theoretical level, the application of topological quantum theory in model insulators and how he was able to achieve the mayoral Naphemites through some of the underlying carbon-based integrated circuit elements, as well as Josephson's knots.

Objectively, it's kind of hard to understand him as an application researcher, to understand those complex physical-mathematical formulas.

Fortunately, though the formula accounts for more than 70%, there are dynamic graphics as a demonstration that do not make them completely incomprehensible.

Just after listening to this “Don't Live" lesson, he felt like he had spent decades building a world view that was almost entirely refreshed.

It took less than a second to disassemble the product of a prime number greater than 1024 bits, which at least means that the calculator in his hand, the quantum bit, was at least 500 or more.

But it's not the most critical, the most critical thing is that this quantum computer is just the size of a slap! I don't know how many times smaller than that quantum computer at the Chinese Academy!

And for horizontal contrast, they only get the best results with 20 quantum bits…

That's it, and it's the latest this year.

Beyond that, what shocked him more than that box-sized quantum computer was the Master Lu himself standing on the stage and telling them about these theories.

Mathematics, Physics, Materials, and Integrated Circuit Design… If you break it down a little bit, you can even break down a dozen discipline branches into the knowledge points covered by this lesson.

However, for a young man under the age of thirty, the profound and obscure knowledge in his hands, like a believer, had no obstacle to its application.

If he hadn't seen it with his own eyes, he couldn't believe that someone in the world could really be that good.

Perhaps that's why he can overcome one world class problem after another...

In the car parked in front of the Academy, Yanagi suddenly sighed with emotion.

“I feel… maybe I need to go back to school and refresh. ”

Director Li's expression was rather calm.

Surprised, after all, it was only about the technology itself. As for the deep theory, he didn't understand it anyway, so he didn't even think about it.

Looking at the glittering Yanagi, he comforted him with words.

“... After all, it is Master Lu, his class is really difficult to understand, don't take it too seriously. I'm sure you don't understand, even if someone else is sitting here. ”

“It's not a matter of not wanting to," Yanagi shook his head and said, “It's just that sometimes I really feel like I can't keep up with the times anymore. ”

“Though the topic of topological quantum computing is quite novel, some of us are doing it, and the target is Microsoft's Mayora Nafemi project. However, whether it's the Pan Yard project, or the Microsoft project that we have, or Microsoft's own... quantum bits have never been more than twenty or thirty. ”

As soon as he heard about this place, Director Li couldn't care less to comfort him. He asked hastily.

“How much did Professor Lu do? ”

Mr. Liu: “I forgot to ask how much, but from what I've just seen… at least 500 is there. ”

500…

This has to be an order of magnitude!

The cabin was silent for a long time.

After a while, Director Li sighed back like a god.

“… is quite frightening indeed. ”

……

If monolithic technology itself is important, quantum computers are undoubtedly much more important than carbon-based chips themselves.

Even though it is not exaggerated, even controllable fusion techniques can be compared together.

According to the accepted view, the three pillars of modern technology are energy, information and materials, and quantum computers are essentially at the pinnacle of future information technology fantasy and hope in this century.

And it's not just that.

Most importantly, traditional encryption is like stripping naked in front of a quantum computer, completely unprotected.

This is also the scariest part of the technology.

It is well known that more than 90 percent of modern information network security relies on asymmetric public key encryption, not just IT and finance, the most widely used of which is RSA encryption algorithms.

Since there is no fixed formula for factorial decomposition of algebraic products, and only the only solution, in principle as long as the product of algebraic numbers used is large enough, it is basically insoluble, even if Professor Lu counts it is not possible to calculate it in his lifetime.

In front of quantum computers, however, this problem, which takes hundreds of years to solve for traditional computers, can be solved in seconds or even less.

Even if one might say that the asymmetric public key encryption algorithm is not just RSA, it also has elliptical curve encryption, Elgamal encryption, etc. These discrete log-based schemes...

But what does quantum computer count for?

I'm afraid we can't even talk about trouble.

After returning home at night, the ark in front of the desk thought for a long time, and eventually came up with a letter that was written on it with a fountain pen.

… the changes brought about by quantum computers in the field of communications technology will be disruptive.

Communication technology encryption and decryption have always been in a dynamically balanced state of development, yet the breakthrough in topological quantum computing has broken the balance between such defenses.

Decrypting a traditional asymmetric public key encryption problem will only take a few seconds.

Once popularized, this technology will bring tremendous development to our societies, but also tremendous security risks.

It is now imperative that we have a stricter and more reliable encryption algorithm in place of the original encryption.

A quantum encryption algorithm similar to the bb84 protocol is a good option, but it will still look overwhelming in the face of quantum computers with over 1,000 quantum bits.

And over 1,000 quantum bits of quantum computer technology, in my opinion, can be broken in a short time.

Therefore, this new encryption rule must be more reliable than the bb48 protocol, or even go beyond its improved version of BBM92.

Once this new encryption technology is mastered, it is the best time to advance the commercialization of quantum computers.

And by then, we will have information technology advantages that no other country can match.

Just as controllable fusion technology has created advantages for us in the field of energy.

The pen stopped, the ark found an envelope in the drawer, stuffed it in, and threw it at the corner of the table.

When he goes to Jinda tomorrow, he will throw it to Wang Peng and ask him to send it to Chang 'an Street in Beijing.

Although he feels that even if he doesn't say anything, Director Lee will certainly report to the top, sometimes expert opinions will be more useful and more likely to attract high-level attention on such issues.

Although these things are not something that a scholar needs to worry about, the Ark still hopes, if it can, that its research will have some positive impact on the world, rather than pushing it in a bad direction.

Though it may not be as exciting as scientific research itself.

But it's also part of the fun.
