Xu You knew that it must be because the news of the successful research on the molding process of 202K superconducting materials reached Han Shubin's ears.

This is undoubtedly a very important achievement for the island plan.

This is one of the few projects that can afford such expensive materials.

Of course, in the long run, if materials with a higher superconducting critical temperature can be used, this may be a technology that can reduce costs.

When Han Shubin met Xu You, he was also in a very good mood.

"Xu You, I went to an academic exchange meeting a few days ago and communicated directly with several Nobel Prize winners? This time you are really the face of Chinese academic circles. We academicians can't reach your level."

"Thank you, Academician Han."

"However, your future will be brighter than all of us. It's a pity that I really couldn't leave a few days ago, otherwise I would definitely go to the scene to listen to your speech."

Xu You still remembers that in the meeting of the Island Project two years ago, Han Shubin was the focus of the audience, and he was only brought here by Wang Xiangwu for the meeting.

Unexpectedly, two years later, Xu You has achieved a leap in status, and even Han Shubin wants to listen to his own meeting below.

After the two chatted about the academic exchange meeting for a while, Han Shubin talked about his reasons for coming to Xu You.

"Xu You, I greeted the higher-ups, and I would like to ask you to come to the island project to help out. The island project is currently in a critical stage of tackling, and the superconducting project has been a little easier recently, and you don't need to do too many tasks. Of course, if there is a need there, you can go back immediately. Xu You, what do you think?"

"Sure, Academician Han. I'm just a brick in scientific research, and I can move it wherever I need it." Xu You smiled.

"Even if you are a brick, you are also a gold brick. Then let me tell you about the progress and difficulties of the current project."

"Okay, Academician Han."

"After our discussion, we have decided to put our energy on the superconducting quantum computer first. It's not that the quantum of light has been completely given up, but for now, the superconducting quantum is definitely more promising in the short term, and it is easier to enter the practical world. stage. Our current plan is to manufacture a superconducting quantum computer with more than 1,000 qubits next year."

"More than 1000?" Xu You asked in surprise.

Xu You remembered that the previous generation of Huaxia's superconducting quantum computer, Wenyuan No. 2, only had 66 bits.

All of a sudden, the number of bits can be increased so many times?

"That's right, in this generation, we only wanted to do more than 100, but with the support of multiple technologies, we are fully capable of achieving more than 1,000. In this, you have taken a lot of credit .When the basic technology is sufficiently developed, the number of qubits can easily grow exponentially.”

For a quantum computer, the impact of the number of qubits on performance cannot be said to be absolute, and is also related to other conditions such as the accuracy of the bit gate.

But each additional qubit doubles the potential capacity of a quantum processor.

Therefore, all major quantum computer research institutions are working hard to create quantum computers with more bits.

"Xu You, we are currently developing a new type of quantum chip. The process of quantum chips is very complicated and requires the joint efforts of a team, but I believe that you should already know a lot about quantum chips. Your joining will definitely help The project has been of great help.”

Xu You used his spare time to learn all the knowledge about quantum chips.

"Academician Han, I have already learned the theoretical part of the knowledge, but there are many things that need to be practiced in the field to know the specific operation method."

"That's natural. When you make a schedule, you can come to me and participate in the project."

After that, Xu You reported the matter to Xing Shuping and Qiao Sen respectively.

Knowing that Xu You was going to participate in another national project, neither Xing Shuping nor Qiao Sen had any objections.

For the superconducting project, the key problems have been solved by Xu You, so there is no need for Xu You to worry too much for the time being.

After dealing with the matter here, Xu You came to the new project team - the island project project.

This time, Xu You did not appear as the mainstay principal researcher like in the superconducting project.

Instead, by Han Shubin's side, he advanced possible understanding of the specific research methods of various steps in the actual research and development of superconducting quantum computers.

Especially the quantum chip is a problem that Xu You needs to focus on helping Han Shubin solve.

Because so far, the world's research on quantum chips is at a relatively early stage of exploration.

The technologies are not very mature.

Therefore, the gap between us and foreign countries in quantum chips is not insurmountable.

Compared with classic chips, it is easier to catch up.

Roughly estimated, in terms of quantum chips, there is still a gap of three or four years between Huaxia and the international leading level.

The success of the island plan this time is very critical.

If we say that in the future, quantum chips will be dominated by foreign companies like traditional chips.

The cost we will have to pay in the future is probably unimaginable.

The phenomenon of stuck neck will become more serious.

"So far, there is no mature quantum chip EDA software on the market. Our self-developed quantum chip EDA tool has been upgraded on the basis of traditional design and simulation, and includes a self-developed quantum chip core simulation program. .” Han Shubin said.

Like traditional chips, the design of quantum chips also requires EDA software.

In the manufacturing process, due to the particularity of quantum chips, highly specialized engineers are needed to gradually debug the working process parameters.

In these respects, Xu You couldn't help easily.

Han Shubin didn't expect Xu You to help in production, but more in theory and design.

After a period of practice, Xu You has a complete understanding of the design, production and manufacture of the entire quantum chip.

At this time, Han Shubin explained to Xu You that there is currently a major problem encountered in the quantum chip.

"Xu You, you know that the computing power of a quantum computer is determined by the number of qubits and the fidelity of a single bit. At present, we have the ability to achieve more than 1,000 qubits. However, As the number of qubits increases, we run into another problem."

"Academician Han, is the fidelity of the single bit affected?"

Hearing Xu You's words, Han Shubin also nodded.
