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

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

Compared with design, the manufacturing of lithography machines is a bigger problem.

It can be said that even if we put the drawings of high-precision lithography machines in front of us, it will be difficult for us to complete the manufacturing of lithography machines.

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

To complete such a job, a lot of money is required and a large number of relevant technical R&D personnel are required.

"I also understand this. We have provided financial support for Magic City Microelectronics and are also studying some related technologies. However, at this progress, it will take at least a few years to wait until the technology of the 7nm chip matures.

”

In a few years, it is actually not slow to achieve such a breakthrough.

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

At this time, Xu You put forward another idea.

"In fact, there is a direction that has the hope of overtaking on the curve. I don't know if you want to give it a try."

Luo Wenkun asked back after hearing this: "You mean, can you be a quantum chip?"

"That's right, it's a quantum chip. Quantum chips have obvious advantages in computing speed, and there is no need to use an extremely high-precision lithography machine to complete the preparation work."

"But, don't quantum chips need to be operated at very low temperatures? If you want your phone to reach such a low temperature, it will definitely occupy a lot of space, right?"

Luo Wenkun also had some understanding of 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 chip does not involve superconductors and does not require low-temperature conditions.

, it can run."

After hearing what Xu You said, Luo Wenkun also became interested.

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

"There is indeed hope. It's just that because it's more difficult to program optical quantum, we also choose the direction of superconducting quantum in the research of quantum computers."

"So...is there any hope?"

Luo Wenkun's mood jumped repeatedly with 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 can complete the research on optical quantum chips within one year."

"I understand, then let's start the project immediately."

After receiving Xu You's affirmative answer, Luo Wenkun chose to believe Xu You without hesitation and launch this new project.

If we can really study practical optical quantum chips.

From then on, the world's chip structure will undergo a huge reversal.

Not only will it solve the problem of getting stuck in your neck, but we will even have the advantage in turn.

After discussions by management, Fulong Technology unanimously agreed to the development of this project.

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

Luo Wenkun has also been prepared before. If other senior 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 support his research through other channels.

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

In order to facilitate Xu You's research work, Luo Wenkun opened a "Photoxin 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.

This laboratory was successfully opened.

In addition to Xu You and the R&D members of Fulong Technology.

Some students from Jijing University also entered this laboratory to conduct internships.

The ability to participate in the research of this cutting-edge project is also one of the original intentions of the school to open this laboratory.

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

Xu You officially planned this project.

Optical quantum chips are not completely detached from traditional chips.

Like traditional chips, optical quantum chips also use silicon-based.

However, in terms of information carriers, there are fundamental differences between the two chips.

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, the transmission method is not the same.

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

The optical signals in silicon-based photonic chips are transmitted in waveguides.

"First of all, we need to determine the problem on the optical quantum chip manufacturing platform." Xu Youxin thought.

On this issue, Xu You is not unable to start, but has a lot of experience.

In fact, when he first came into contact with scientific research, Xu You studied the photo quantum problem.

At that time, Xu You was just a laboratory intern and was studying Zhao Weijia's topic.

Later, by chance, Zhao Weijia solved some key problems.

After that, Xu You officially released the first paper, which also involved light quantum.

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

However, the research experience of these optical quantum projects has greatly helped Xu You's current research on optical quantum chips.

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

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

This lithium-containing compound has excellent electro-optical properties, wide transparent windows, high refractive index, and high stability.

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

After determining the manufacturing platform of optical quantum chips.

Xu You and his team started the design of optical quantum chips.

Due to different structures, optical quantum chips do not require such strict processing technology like traditional chips.
