Chapter 386 The Dilemma of Optical Quantum Chips

With our existing lithography machine technology, it is completely possible to complete the processing of optical quantum chips.

If it is really possible to make optical quantum chips with powerful performance, then our pursuit of high-precision lithography machines will not be so urgent.

Of course, before everything is concluded, the research and development of optical quantum chips and traditional silicon-based chips must be explored at the same time.

It is not possible to put all our energy on it because the optical quantum chip has a very good prospect.

In the design of optical quantum chips, there is a very difficult problem to solve.

That is programmable photonic integrated circuits.

Before Han Shubin's quantum computer team was developing optical quantum computers.

There is no good solution to the problem of optical quantum programming.

This is why later, we focused the focus of quantum computers on superconducting quantum computers.

A so-called "quantum computer" that cannot be programmed to solve complex problems.

Its practical application value is very small.

No matter how fast its calculation speed is, more of it is only of experimental significance.

In order to help the project team to carry out the research work.

Xu You specially invited Han Shubin's quantum computer team to discuss the design of the optical quantum chip.

"In photonic integrated circuits, the optical path and functions are fixed, and cannot be applied to a variety of application fields and application scenarios. Therefore, the photonic integrated circuits manufactured by our team before are all aimed at a specific application, and the other designed and manufactured."

Han Shubin straightforwardly explained his team's design scheme for optical quantum chips in previous optical quantum computers.

"Academician Han, what changes do you think we need to make to make optical quantum chips actually applied to mobile phones or home computers?" Xu You asked.

Regarding Xu You's question, Han Shubin also showed some embarrassment.

"If it is changed, it must be adjusted from a specific application to a wide range of applications. To achieve this, I am afraid that the grid unit structure needs to be completely changed."

This sounds simple, but it is very difficult to do it.

Otherwise, Han Shubin's team will not abandon the direction of optical quantum computer with lower cost and faster calculation speed, but choose the direction of superconducting quantum computer with higher cost and slower calculation speed.

After receiving such a response from Han Shubin, Xu You was not too discouraged.

Xu You was mentally prepared for what Han Shubin said.

But anyway, through the information provided by Han Shubin and his team.

At least let Xu You know which roads will not work and which key problems need to be solved.

In the following time, Xu You tried to simulate this function through brain simulation to design a new photonic integrated circuit.

With the lessons learned from overloading his brain last time, Xu You never dared to use his brain power excessively again.

After all, the water flows for a long time, and only when the green hills are left can we continue to carry out scientific research.

Even if the problem cannot be solved for a while, life still has to go on.

If you can't go in this direction, then go to another direction.

On this day, Lu Zhiyao contacted Xu You and said that if there was nothing else to do, she would go home early and cook at home in the evening.

Xu You hadn't eaten at home for a long time, so he readily agreed to Lu Zhiyao's proposal.

"Chef Yaoyao, what do you want to do tonight?"

"Didn't I buy an oven earlier. How about baking a pizza tonight? With green salad and wine?"

"Pizza? Is it the kind that is processed and baked directly?"

"Of course not. The processed ones don't taste good. I bought all kinds of raw materials and made them myself."

"Amazing! Yaoyao, can you even cook Western food?"

Before that, Lu Zhiyao always cooked Chinese food, and Xu You hadn't tasted Western food made by Lu Zhiyao.

Lu Zhiyao shook her head and said, "I haven't done it before, but I still know how to do it. I think Western food is simpler than Chinese food."

Xu You nodded in agreement, because there are many fast foods in Western food, which are very convenient to make and eat.

Eating a hamburger or something when you are busy will indeed save time.

"It's done for a while, you can go to work first, and I'll call you when it's done."

"Yaoyao, let me help you do it together."

The current Xu You does not race against time to go to work regardless of the occasion.

Only by relaxing occasionally and returning to life can we have a better working state.

"That's okay. But I have to ferment the dough first, and then I can start making dough cakes. Let's make it together after the dough is fermented."

Seeing what Lu Zhiyao said, Xu You went back to the room first.

After returning to the room, Xu You didn't really go to work, but picked up the books that he hadn't read before.

No matter how busy he is at work, Xu You will keep the habit of reading.

Even in the war years, those great pioneers would take time to read and study, and constantly improve themselves.

If you put all your energy on work, it is easy to make your vision very limited.

Before I knew it, an hour passed.

After the dough fermented, Lu Zhiyao came to the room to find Xu You.

"Xu..."

Seeing how serious Xu You was reading the book, Lu Zhiyao couldn't bear to disturb Xu You for a while, but just as she opened her mouth, her voice stopped abruptly.

Xu You, who was in a state of deep learning, didn't feel that Lu Zhiyao came in at all, since he was intoxicated in the world of books.

"The way he studies is really serious." Lu Zhiyao said heartily.

Except for being a few years older, Xu You's serious temperament is the same as in high school.

This made Lu Zhiyao give up the idea of ​​cooking with Xu You.

Lu Zhiyao put on the cat apron again and started the making process of the dough cake.

At this time, Xu You had finished reading all the books that he hadn't read before.

"Phew, there are still too few books to buy. I have to ask Teacher Cui to help me buy more next time."

With Xu You's fast reading speed, more than a dozen books are indeed not enough to satisfy his hunger.

"Why didn't Yaoyao come to call me...the noodles haven't fermented yet?"

Xu You glanced at the time and found that it had exceeded the expected fermentation time.

Xu You walked out of the bedroom, and saw that Lu Zhiyao had already made noodles in the kitchen.

"Yaoyao, didn't you say that we should make it together after the noodles are fermented?"

"Well... I called you just now, and saw that you read so seriously, so I didn't bother you. It's okay, I can do it by myself. "

Xu You blamed himself a little when he heard the words. In the state of deep learning, it is really difficult for him to feel the fluctuations of the outside world.

Xu You quickly took off the other cat's apron and put it on his clothes.
