After a brief adjustment, life is back on track again.

At present, one of the projects that Xu You is most concerned about is the "Analysis" project.

And because Huaxin International has not yet solved the problem of the preparation process of the new optical quantum chip, the "Suan Jing" project cannot continue.

"If not, I'll go there myself."

Xu You didn't want to interfere too much with the research work of other companies, but he also didn't want to fall into endless waiting.

After making this decision, Xu You contacted the person in charge of the project at Huaxin International through Luo Wenkun, and proposed the idea of ​​wanting to understand the progress of the project.

After receiving Xu You's request, Huaxin International attached great importance to it, and immediately arranged a special person to receive Xu You.

Under the escort of several bodyguards, Xu You came to Huaxin International.

"All etiquette can be omitted, just take me to the project team."

"Okay, Professor Xu, please follow me."

After coming to the project team, Xu You chatted with several main researchers about the progress of the project.

Through understanding, Xu You understands the main problems encountered in the current project.

"Professor Xu, we have tried to use several silicon-based photonic chip manufacturing platforms. These methods had a very high yield rate in the previous chip manufacturing, but in the trial processing of the new photonic chip, the integrated Problems such as low device refractive index contrast and large device size have caused a series of device performance degradation results."

These problems have seriously affected the quality of the chip.

Not to mention mass production, it is still impossible to produce a standard chip.

"Have you found the specific reason?" Xu You asked.

"Under research, the high probability should be related to the improvement of the chip manufacturing process."

Listening to the tone of these researchers, Xu You knew that they were not very sure about the specific reason.

That being the case, Xu You could only do it himself.

"Please let me know the specific information."

Xu You didn't blame them in any way, after all, this was a task that the whole world hadn't tried before.

However, our chip processing technology is still in the stage of catching up, and it is very normal to encounter these difficult problems.

"Okay, Professor Xu."

They have been told before that Xu You has the right to know all the information.

Regarding Xu You's question, they had to say everything they wanted to say.

After some detailed exchanges, Xu You basically understood the whole situation.

"Wait a moment!"

At this moment, Xu You suddenly remembered something.

Before, in the conversation with Huang Sibai, Huang Sibai and Xu You talked about some chip manufacturing technology.

And one of the technologies can solve these problems.

After returning from Huaxin International, Xu You contacted Huang Sibai through Fulong Technology.

"Huang Gong, are you still in the head office of Fulong Technology?"

"Yes, Professor Xu, do you have something to ask me?"

"Well, I want to exchange a technology with you. If you have time, is it convenient to come to Jijing University?"

"It's convenient and convenient. It just so happens that I don't have anything important to do now. I can go there in a while."

"Okay, I'll wait for you at school."

Same as last time, Huang Sibai was still very active this time, and he came to Jijing University not long after.

"Huang Gong, I remember that before, you said that there is a chip manufacturing platform that can solve the problems of low refractive index contrast and large device size of integrated devices. Is there such a thing?"

"Let me think about it... Yes, I told you about this a while ago. This problem can be solved through the intelligent cutting technology of the wafer."

Next, Huang Sibai explained to Xu You in detail how to build the new platform and how to solve this problem.

"Combining wafer bonding technology and crystal ion slicing technology, single-crystal lithium niobate thin films can be prepared. Using this method, lithium niobate waveguides with high refractive index contrast can be fabricated to improve device performance and reduce its footprint... "

Xu You listened carefully to Huang Sibai's explanation, and at the same time tried to simulate the corresponding scene in his mind.

"Huang Gong, do you have any specific pictures or other information?"

"Professor Xu, I came here in a hurry today, and I didn't bring any relevant materials with me. In this way, after I go back, I will sort out the materials and send them to you."

"Okay, then trouble Huang Gong."

Because the information obtained so far is not detailed enough, Xu You can't accurately simulate the corresponding scene in his own brain.

According to Xu You's preliminary analysis, the same platform may not be fully suitable for direct use in the production of new optical quantum chips.

But as long as you follow this line of thinking and make some modifications and optimizations, it is very hopeful that the problem will be completely solved.

After talking about this, Huang Sibai did not leave immediately.

"Professor Xu, it's convenient to ask, in what kind of scene did you encounter this problem? If you can let me know more in detail, I may be able to give more detailed suggestions."

Because of their status, these researchers who had just returned to China were not invited to those secret projects.

Xu You hesitated for a moment, but still did not disclose specific information to Huang Sibai.

"Huang Gong, don't bother me for now. If I need more help from you, I will ask you again."

Xu You tactfully rejected Huang Sibai's request. On the one hand, it was because of safety considerations. On the other hand, with the current situation, Xu You already had hope to solve this problem, so there was no need to bring Huang Sibai in again.

After all, this is important information about the next generation of quantum computers - "Sunjing", so we still can't take any risks.

Huang Sibai also understood what Xu You meant and didn't ask further.

"Okay, Professor Xu, come to me anytime if you have any questions."

After returning, Huang Sibai sent the relevant information to Xu You as promised.

With these detailed information, Xu You can more accurately simulate the manufacturing process of integrated devices.

...

In the dark.

A man in black, holding an unknown device, was whispering something.

"They seem to be researching new optical quantum chips. The process technology is very high, and EUV lithography machines are needed."

"Is it the chip of the next generation Fulong mobile phone?"

"It's not clear yet, but what is certain is that once they successfully create this chip, the performance will definitely not be underestimated."

"According to our ban, they can't use EUV lithography machines to mass-produce their chips. It won't be..."
