Unexpectedly, a few years later, Zhao Weijia has become a teacher in the quantum physics laboratory.

But still can't understand the mysterious formula introduced by Xu You.

At this time, Wang Xiangwu also came over and checked Xu You's derivation process on the paper.

"Mr. Xu, you determined the value of rN-1 by scanning the current of the phase shifter N-1 and measuring the value of the corresponding beam splitting ratio T?"

After all, Wang Xiangwu is the leading professor in the quantum physics laboratory. After replacing the powerful "Rocket Heart" artificial heart, he has almost inexhaustible energy.

Wang Xiangwu got to the point right away, and Xu You nodded after listening.

"That's right, Mr. Wang. In the same way, if we record the quantum state before reaching N-2 as φN-2, we can also get the beam splitting ratio of the output terminal Out1..."

Han Shubin also came closer and joined the discussion between the two.

The three of them are world-class experts in the quantum field, and they quickly reached an agreement.

"It's amazing, Professor Xu! The whole derivation process is really too wild and unconstrained. I never thought of it before, and there is such a derivation idea!"

"Yes, in this way, the quick calibration of multiple phase shifters can be completed. And there is no need to consider whether the number of phase shifters is odd or even, because the first and last phase shifter Adding the π phase at the same time will not affect the beam splitting ratio T."

Zhao Weijia tried hard to understand the discussion of the three, but no matter how hard Zhao Weijia racked his brains, he couldn't integrate into the discussion of the three.

In desperation, Zhao Weijia had no choice but to give up discussing with these three experts, and decided to get to know each other slowly.

...

After solving the key problems, Xu You and others began to enter the design stage of optical quantum chips.

The design concept this time is to increase the computing speed of the chip as much as possible while ensuring smooth programming.

This is also the fundamental purpose of Xu You's proposal of the project "Analysis of the Classics".

The calculation speed of the island quantum computer is already very fast, but it is far from reaching the standard in Xu You's mind.

If you want to solve more complex problems, the faster the calculation speed, the better.

In the process of designing this chip, Xu You also continuously carried out simulations, simulating the actual calculation effect of this chip.

Xu You also felt a little unbelievable.

This chip not only achieves exaggerated computing speed, but also achieves extremely high fidelity at the same time.

It is conservatively estimated that the fidelity distribution of the output state exceeds 99.99%.

Such data even far exceeds the island quantum computer and the Vulture quantum computer just released by IBM.

Once the "Analysis" is completed, it will form a dimension-reducing blow to the vultures!

After completing the design of the chip, the next job is to manufacture the chip.

"Professor Xu, this optical quantum chip should need an EUV lithography machine because of the processing technology problem?"

"Yes, this chip still has high requirements for processing technology. But because our quantum computer project is not on the Bald Eagle's ban list, processing this chip will not be restricted."

EUV lithography machine, that is, extreme ultraviolet lithography machine.

Some chips with extremely high process technology can only be manufactured using EUV lithography machines.

Although we have not independently developed EUV lithography machines, there are still some EUV lithography machines purchased from ASML in China.

Just producing a handful of chips for use in quantum computers isn't as constrained as it is for Vron mobile phones.

With the design drawing of the chip, Xu You and others found the relevant personnel of Huaxin International.

Huaxin International has no reason to refuse the request to produce this chip.

However, during the trial production process, the ideal chip was not produced.

"We have never done this kind of process before, and it is very different from normal silicon-based chips. We may need to formulate a unique processing plan for this optical quantum chip."

"Well, this will trouble you."

Huaxin International is already the company with the strongest chip manufacturing technology in China. If Huaxin International cannot solve the problem, then other domestic chip manufacturers will most likely not be able to solve it.

Before returning, Island Semiconductor's technology cannot be used by us.

After explaining this task, Xu You looked forward to them bringing him good news as soon as possible.

"I don't know when we will be able to build our own EUV lithography machine."

At this stage, due to our rapid development, the West has become more and more aggressive in restricting our chips.

Their purpose is to completely exclude us from the world's semiconductor industry chain, curb the development of our technology, and consolidate their so-called "scientific and technological hegemony."

To achieve self-sufficiency in high-end chips, EUV lithography machine is an essential technology.

To some extent, EUV lithography machines are even more difficult to manufacture than atomic bombs.

An EUV lithography machine needs more than 100,000 parts and comes from more than 5,000 companies in more than 30 countries.

It is very difficult for us to complete the manufacture of EUV lithography machines with the strength of a country.

But this day, during the conversation with Luo Wenkun, Xu You got a piece of good news.

"Xu You, do you remember that Huang Sibai from before?"

"Of course I remember, isn't it the engineer who worked at ASML. What's wrong?"

"Huang Sibai recently made an important achievement, which brought us one step closer to the self-developed EUV lithography machine."

"Great. May I have a look at the result?"

"Of course, when Huang Sibai has time, I'll let him come to Jijing University."

"Okay, don't ask him to come here in a hurry, just work on his project first. When it's all right, let him come over."

Thinking that the domestic EUV lithography machine is getting closer, Xu You couldn't restrain his excitement.

"The engineers who came back from ASML are really different."

These researchers who have worked in overseas technology companies have a great advantage in experience.

Even Xu You felt that it was not worthwhile for Bald Eagle to use special intelligence personnel in exchange for these talents to return to the country.

But in any case, this is also a trade that everyone gets what they want.

What Xu You didn't expect was that Huang Sibai came to Jijing University soon.

"Professor Xu, you are looking for me."

"Huang Gong, aren't you busy with work recently? I told Mr. Luo that you don't need to rush over here, just get busy with the work at hand first."

Xu You is not in charge of the research project of EUV lithography machine, and Huang Sibai is called here, more just to learn some cutting-edge knowledge.
