Scholar’s Advanced Technological System

Chapter 1179: Five hundred qubits!

After coming out of the Jinling Institute of Advanced Studies, Liu Academician felt that the whole person was like a sleepwalker, and his head was in chaos.

After the physical demonstration, Lu Zhou then explained the application of topological quantum theory to the model insulator from the theoretical level to the experts from the Chinese Academy of Sciences, and how he integrated through some basic carbon-based Circuit components and Josephson knots to achieve the Mayorana Fermi son.

Objectively speaking, if you want to understand him and engage in applied research, it is somewhat difficult to understand complex physics and mathematics formulas.

Fortunately, although the formula accounts for more than 70% of the parts, there are dynamic graphics as a demonstration, so that they do not let them completely understand the mystery.

It was only after listening to this "Don't Make a Difference" class, he felt that he had spent thousands of years establishing a world view, and almost the whole was refreshed.

It took less than a second to disassemble the product of more than 1024 prime numbers, which at least illustrates the calculator in his hand, with at least 500 qubits.

However, this is not the most critical. The most important thing is that this quantum computer is only the size of a palm! The size of the quantum computer in the Chinese Academy of Sciences is not known how many times smaller!

And if they are horizontally contrasted, they do the best, only 20 qubits...

This is the latest result of this year.

In addition, compared to the quantum computer of the size of the box, what shocked him was the academician who stood on the stage and explained the theory to them.

Mathematics, physics, materials, and integrated circuit design... If you are more detailed, the knowledge points covered in this lesson can even be subdivided into more than a dozen branches.

However, for those young people who are less than 30 years old, the esoteric and awkward knowledge is in his hands like a handkerchief. There is no obstacle in using it.

If he didn't see it with his own eyes, he couldn't believe it. There are really people in this world who can be excellent to this extent.

Perhaps this is why he can overcome one world after another...

Sitting on the car parked at the entrance of the institute, Liu Academician suddenly sighed with emotion.

"I feel... maybe I need to go back to school and re-learn."

Director Li’s expression is still calm.

After all, the surprise was a surprise. It was only for the technology itself. As for the esoteric theories, he couldn’t understand it anyway, so he didn’t go to the heart.

Looking at the sly Liu Academician, he said comfortably.

"... After all, it is an academician of the army. His class is really difficult to understand. Don't go too far. I don't believe that you can't understand it, even if other people come here to sit."

"It’s not a question that goes to my heart," Liu said, shaking his head and saying, "It’s just that sometimes I really feel that I have been unable to keep up with this era."

"The topic of topological quantum computing is relatively new, but there are people in our field who are doing it. The target is Microsoft's Mayorana Fermi son's project. However, whether it is the project of Pan Academician, or the one in our company. The project against Microsoft, or Microsoft's own... Qubit is always just above the 20th and 30th."

Upon hearing this, Secretary Li did not care for him, and asked quickly.

“How much did Professor Nalu do?”

Academician Liu: "I forgot to ask how much, but as far as the presentation is concerned... at least 500 is there."

500...

This is an order of magnitude higher!

The car was silent for a long time.

After a short while, Director Li returned to the faint sigh of sigh.

"...is really scary."

......

If the importance of the technology itself is single, the importance of the quantum computer is undoubtedly far beyond the carbon-based chip itself.

It is even exaggerated to say that even the controllable fusion technology can be put together.

According to the accepted view, the three pillars of modern technology are energy, information, and materials, and quantum computers have basically stood in this century's imaginary and hopeful realization of future information technology.

And not just that.

The most important thing is that the traditional encryption method is like being stripped out in front of the quantum computer, and it is completely undefended.

This is also the most terrible place for this technology.

As we all know, not only IT and finance, the security of modern information networks relies on asymmetric public key encryption, and the most widely used one is the a encryption algorithm.

Since the factorization of large prime products has no fixed formula and only a unique solution, in principle, as long as the product of the prime numbers used is large enough, it is basically equal to no solution, even if it is not for Professor Lu. It may be calculated in the lifetime.

However, in the face of quantum computers, this problem that requires hundreds of years to solve for traditional computers can be solved in a matter of seconds or even seconds.

Even if one might say that the asymmetric public key encryption algorithm is not just a, there are elliptic curve encryption, elgamal encryption, etc. based on discrete logarithm...

But what is it in the face of the computing power of quantum computers?

I am afraid I can't even talk about the trouble.

After returning home at night, Lu Zhou, sitting at the desk, thought for a long time, and finally took out a stationery and wrote it on it with a pen.

... The changes brought about by quantum computers in the field of communication technology will be subversive.

The encryption and decryption methods of communication technology have always been in a state of dynamic balance. However, the breakthrough of topological quantum computing technology has broken the balance between this offensive and defensive.

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

Once this technology is popularized, it will bring huge security risks to our society.

The immediate priority is that we must establish a more rigorous and more reliable encryption algorithm as a replacement for the original encryption method.

A quantum encryption algorithm similar to the bb84 protocol is a good choice, but a quantum computer with more than 1000 qubits will still be incapable.

The quantum computer technology of more than 1000 qubits, 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 an improved version of bbm92.

Once you master this new encryption technology, it is the best time to promote the commercialization of quantum computers.

And by that time, we will have the information technology advantages that other countries cannot match.

Just like the controllable fusion technology, the advantages we have built for us in the energy field.

After stopping the pen, Lu Zhou found an envelope from the drawer, stuffed the letter into it, 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 find someone to go to Chang'an Street in Beijing.

Although he feels that he does not say anything, Director Li will certainly report to it, but on this issue, sometimes the opinions of experts will be more useful, and it will be more likely to attract the attention of the top.

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

Although this may not be as exciting as the scientific research itself.

But it is also part of the fun.
