"For the lithography machine, I really don't have a good solution. This is not a problem that can be solved by one person, but requires a lot of high-end talents."

Xu You also understands the difficulties of high-precision lithography machines.

Compared with the design, the manufacture of the lithography machine is a bigger problem.

It can be said that even if the drawings of the high-precision lithography machine are in front of us, it is difficult for us to complete the manufacture of the lithography machine.

The lithography machine has too high requirements for manufacturing precision, and Xu You has no experience in high-precision preparation.

To complete such work, a lot of money is required, and a large number of related technical R\u0026D personnel are required.

"I also understand this. We have provided financial support to Modu Microelectronics, and we are also researching some related technologies. However, according to this progress, it will take at least a few years until the technology of 7nm chips matures. "

In a few years, it is not too slow to complete such a breakthrough.

However, compared to Luo Wenkun's goal, such progress still cannot satisfy Luo Wenkun.

At this time, Xu You came up with another idea.

"Actually, there is a direction, and there is hope to achieve corner overtaking. I don't know if you want to try it."

Luo Wenkun asked back after hearing the words: "You mean, shouldn't it be a quantum chip?"

"That's right, it's a quantum chip. Quantum chips have obvious advantages in terms of computing speed, and they don't need an extremely high-precision lithography machine to complete the preparation work."

"But, don't quantum chips need to operate at a very low temperature? If you want a mobile phone to reach such a low temperature, it will definitely take up a lot of space, right?"

Luo Wenkun also has some knowledge about quantum chips, and immediately raised his own questions.

"To be precise, it is a superconducting quantum chip that needs to operate in a low-temperature environment. In addition to superconducting quantum chips, there is another quantum chip-optical quantum chip. This kind of chip does not involve superconductors and does not require low temperature conditions. , it will work.”

Hearing what Xu You said, Luo Wenkun also became interested.

"So, there is really hope in this direction?"

"There is indeed hope. It's just because light quantum is more difficult to program. In the research of quantum computer, we also choose the direction of superconducting quantum."

"So...is there any hope?"

Luo Wenkun's mood jumped repeatedly following Xu You's words.

Xu You smiled and said: "Okay, I won't go around in circles with you. The technology of optical quantum chips is definitely not yet mature, but many of my previous research results are closely related to optical quantum chips. As long as there is enough support , I am fully confident that I will complete the research on optical quantum chips within one year."

"Understood, let's start the project immediately."

After getting Xu You's affirmative answer, Luo Wenkun chose to trust Xu You without hesitation and started this new project.

If it is possible to develop a practical optical quantum chip.

From then on, the world's chip pattern will undergo a great reversal.

Not only does it solve the problem of the neck being stuck, but we even have the advantage in reverse.

After discussions with the management, Fulong Technology unanimously agreed to carry out the project.

After all, the temptation of "overtaking on a curve" is too great. Even if this research sounds unrealistic, it is totally worth trying.

Luo Wenkun has also made preparations before. If other high-level officials disagree, Luo Wenkun will also exercise more than half of his voting rights to support the development of this research.

Luo Wenkun knew that if Fulong Technology did not support this research, Xu You might use other channels to support his own research work.

In this way, it will not be so easy for Fulong Technology to use this technology after the research is successful.

In order to facilitate Xu You's research work, Luo Wenkun opened a "photonic core valley" laboratory in Jijing University through his own relationship.

Such an operation is unprecedented.

But with the reputation of Fulong Technology and the significance of this project.

The laboratory was successfully opened.

Except for Xu You and the R\u0026D members of Fulong Technology.

Some students from Jijing University also entered this laboratory for internship.

It is also one of the original intentions of the school to open this laboratory to allow these students of the school to participate in the research of such cutting-edge projects.

After the establishment of the "Photonics Core Valley" laboratory.

Xu You is officially planning this project.

Optical quantum chips are not completely detached from traditional chips.

Like traditional chips, photonic chips also use a silicon base.

However, on the information carrier, the two chips are fundamentally different.

Traditional chips use electrons as information carriers, while optical quantum chips use photons as information carriers.

Compared with electrons, photons have many unique advantages.

Photons have multiple multiplexing dimensions such as wavelength, amplitude, and phase, with larger bandwidth and communication capacity and higher spectrum utilization.

In addition, in terms of transmission methods, the two are not the same.

The electrical signals of traditional microelectronic chips are transmitted in wires.

The optical signal in the silicon-based photonic chip is transmitted in the waveguide.

"First of all, we need to confirm the problems on the optical quantum chip manufacturing platform." Xu You thought to himself.

On this issue, Xu You is not helpless, on the contrary, he has very rich experience.

In fact, when Xu You first came into contact with scientific research, he was studying the photon problem.

At that time, Xu You was just an intern in the laboratory, studying Zhao Weijia's subject.

Later, by mistake, he helped Zhao Weijia solve some key problems.

After that, Xu You's first paper officially released was also about photons.

However, because he was more interested in the superconducting part, Xu You finally chose the direction of condensed matter physics.

The research experience of these photon quantum projects has greatly helped Xu You's current research on photon quantum chips.

Xu You already has several candidates for the selection of the optical quantum chip manufacturing platform.

After many experiments, the project team finally chose a lithium-containing compound as a manufacturing platform for optical quantum chips.

This lithium-containing compound has the characteristics of excellent electro-optic properties, wide transparent window, high refractive index, and high stability.

This makes it an extremely advantageous material platform for building integrated photonic devices.

After determining the manufacturing platform for optical quantum chips.

Together with the team, Xu You started the design of the optical quantum chip.

Because of the different structures, optical quantum chips do not require such strict processing techniques as traditional chips.
