Chapter 420 If not, let me do it

After a brief adjustment, life returned to normal.

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

Because Huaxin International has not yet solved the problem of the preparation process of the new optical quantum chip, the "calculation" project cannot continue.

"If it doesn't work, I'll just go there in person."

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

After making this decision, Xu You contacted the person in charge of the project through Luo Wenkun and put forward his ideas for understanding the project process.

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

"Okay, Professor Xu, please come with me."

After arriving at the project team, Xu You and several major researchers talked about the progress of the project.

Through understanding, Xu You understood the main problems encountered in the project now.

"Professor Xu, we have tried to use several silicon-based photonic chip manufacturing platforms. These methods have had a very high yield in previous chip manufacturing, but integration has emerged in the project of trial processing of new optical quantum chips.

The low refractive index contrast of the device and the large device size have caused a series of results of degraded device performance."

These problems have seriously affected the quality of the chip.

Not to mention mass production, even producing a chip that meets the standards cannot be done.

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

"In the process of research, it is likely that it is related to the improvement of chip process technology."

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

Since this is the case, Xu You can only take action personally.

"Please let me know the specific information."

Xu You did not blame them at all, after all, this was a task that the whole world had never tried before.

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

"Okay, Professor Xu."

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

Regarding Xu You’s problem, they must speak out everything they know and say.

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

"Wait a moment!"

At this moment, Xu You suddenly remembered something.

Previously, in a conversation with Huang Sibai, Huang Sibai and Xu You talked about some technologies in chip manufacturing processes.

And one of the techniques can solve these problems.

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

"Mr. Huang, is he still in the headquarters of Fulong Technology?"

"Here, Professor Xu, do you have something to come to me?"

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

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

"Okay, I'll be waiting for you in school."

Just like the last time, Huang Sibai was still very active this time and came to Jijing University not long after.

"Mr. Huang, I remember before, you said that there is a chip manufacturing platform that can solve the problem of low refractive index contrast and large device size in integrated devices. Is this the case?"

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

Next, Huang Sibai explained in detail to Xu You about the construction of the new platform and the methods to solve this problem.

"Combining wafer bonding technology and crystal ion slicing technology, single crystal lithium niobate films can be prepared. This method can create high refractive index contrast lithium niobate waveguides to improve device performance and reduce their area...

”

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

"Mr. Huang, do you have any specific images or other information?"

"Professor Xu, I came here a little urgently today and didn't carry any relevant information with me. In this way, after I go back, I will sort out the information and send it to you."

"Okay, then I'll trouble Huang Ke."

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

According to Xu You's preliminary analysis, if the same platform is directly used to produce new optical quantum chips, it is likely that it will not be fully adapted.

But as long as you follow this idea and make some modifications and optimizations, it is very hopeful to completely solve the problem.

After saying this, Huang Sibai did not leave immediately.

"Professor Xu, please ask me, what kind of scenario are you facing? If I can learn more in more detail, I might be able to give more detailed suggestions."

Due to their identity, these researchers who have just returned to China have not been invited to those secret projects.

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

"Mr. Huang, please don't disturb me for now. If you need more help, I'll ask you."

Xu You politely rejected Huang Sibai's request, on the one hand, because of security considerations, and on the other hand, based on the current situation, Xu You already has hope of solving this problem, so there is no need to bring Huang Sibai in again.

After all, this is important information about the next generation of quantum computers - "computation", and we still cannot take any risks.

Huang Sibai also understood what Xu You meant and did not ask any more questions.

"Okay, Professor Xu, if you have any questions, please contact me anytime."

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 night.

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

"They seem to be studying new optical quantum chips, with high process technology and need to use EUV lithography machines."

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

"It's not clear yet, but it's certain that once they successfully build this chip, the performance should not be underestimated."

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