Chapter 384: The Dilemma of Photonic Quantum Chips
With our existing lithography technology, we can completely complete the processing of photonic quantum chips.
If we can really make high-performance photonic quantum chips, then our pursuit of high-precision lithography machines will not be so urgent.
Of course, before anything is concluded , we must explore both the research and development of photonic quantum chips and traditional silicon-based chips at the same time.
We should not focus .
In the design of photonic quantum chips, there is a very difficult problem to solve.
That is a programmable photonic integrated circuit.
Previously, 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 also the reason why we later focused our research on superconducting quantum computers.
A so-called "quantum computer" that cannot be programmed and cannot solve complex problems.
Its actual application value is very small.
Even if its computing speed is faster, it is mostly of experimental significance.
To help the project team carry out its research work.
Xu You specially invited Han Shubin's quantum computer team to discuss the design plan 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 scenarios. Therefore, the photonic integrated circuits previously manufactured by our team were designed and manufactured for a specific application."
Han Shubin directly explained his team's design plan for the photonic quantum chip in the previous photonic quantum computer.
"Then Academician Han, what changes do you think we need to make in order to truly apply photonic quantum chips to mobile phones or home computers?" Xu You asked.
Han Shubin looked a little embarrassed about Xu You's question.
"If there is a change, it must be adjusted from targeting a specific application to being applicable 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.
Otherwise, Han Shubin's team would not have abandoned the direction of optical quantum computers with lower costs and faster computing speeds, and instead chosen the direction of superconducting quantum computers with higher costs and slower computing speeds.
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 no matter what, through the information provided by Han Shubin and his team.
At least let Xu You know which paths are blocked and which key problems need to be solved.
In the following time, Xu You tried to simulate this function through brain simulation to design new photonic integrated circuits.
Having learned the lesson from overusing his brain last time, Xu You never dared to overuse his brain power again.
After all, only by keeping the flow of water can we continue scientific research.
Even if the problem cannot be solved immediately, life still has to go on.
If this direction doesn't work, then look for another direction.
On this day, Lu Zhiyao contacted Xu You and told him that if there was nothing else, he should 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 cook tonight?"
"I bought an oven a while ago. How about baking a pizza tonight? And some vegetable salad and fruit wine?"
"Pizza? Is it the kind that's baked right after it's been processed?"
"Of course not. Processed ones don't taste good. I buy all the ingredients and make them myself."
"That's amazing! Yaoyao, can you even cook Western food?"
Before, Lu Zhiyao had always cooked Chinese food, and Xu You had never tasted the Western food cooked by Lu Zhiyao.
Lu Zhiyao shook her head and said, "I've never made it before, but I know how to make it. I think Western food is simpler than Chinese food."
Xu You nodded in agreement, because there are many fast Western foods that are very convenient to make and eat.
Eating a burger or something when you are busy will indeed save time.
"It will take a while until it's done. You can go to work first. I'll call you when it's done."
"Yaoyao, let me help you do it."
Now Xu You does not rush to work regardless of the occasion.
Only by relaxing occasionally and returning to life can you be in a better working state.
"That's fine. But I have to let the dough ferment first before I can start making the flatbreads. Let's make it together after the dough is fermented."
Hearing Lu Zhiyao say this, Xu You went back to the room first.
After returning to the room, Xu You did not actually go to work, but picked up the books that he had not finished reading before.
No matter how busy he is at work, Xu You always maintains the habit of reading.
Even in times of war, those great pioneers would take time to read and study, constantly improving themselves.
If you focus all your energy on work, your vision will easily become very limited.
Before I knew it, an hour had passed.
After the dough had fermented, Lu Zhiyao came to the room to find Xu You.
“Xu…”
Seeing how seriously Xu You was reading, Lu Zhiyao couldn't bear to disturb him for a moment. She just opened her mouth but her voice stopped abruptly.
Xu You, who was in a deep learning state, didn't notice Lu Zhiyao coming in at all, as he was immersed in the world of books .
"He seems to be studying really seriously." Lu Zhiyao thought to herself.
Apart from being a few years older, Xu You's serious temperament is no different from when he was in high school.
This made Lu Zhiyao give up the idea of asking Xu You to cook together.
Lu Zhiyao put on the cat apron again and started making the pancakes.
At this time, Xu You had finished reading all the books he had not finished before.
"Huh~ I bought too few books. Next time I'll have to ask Teacher Cui to help me buy more."
With Xu You's fast reading speed, a dozen books are definitely not enough to satisfy his craving.
"Why didn't Yaoyao come to call me...Isn't the dough fermented yet?"
Xu You glanced at the time and found that the expected time for the dough to ferment had passed.
Xu You walked out of the bedroom and saw Lu Zhiyao already making pancakes in the kitchen.
"Yaoyao, didn't we agree to wait until the dough is fermented before we make it together?"
"Well... I called you just now, but I saw you were reading so hard that I didn't disturb you. It's okay, I can do it by myself."
Xu You felt a little guilty after hearing this. In the state of deep learning , it was indeed difficult for him to feel the fluctuations in the outside world.
Xu You quickly took off the other cat apron and put it on over his clothes.
