"For example, if we produce a kind of food by hand for sale, we need to clean the food first, then disinfect it, then cut the food into small pieces, and finally put it into packaging bags to complete the whole process."

"For each step, you need to wait for the previous step to be completed before proceeding."

"How about making this process more efficient? You can use a factory assembly line to perform the steps of cleaning, disinfection, cutting, and packaging at the same time. This is parallelism in time."

"Similarly, spatial parallelism can also be used to achieve higher efficiency."

"Like a traditional computer, it can only stuff data into the processor group by group. A quantum computer can stack multiple groups of data and stuff them in at once. This is why quantum computers can calculate so fast. "

Han Shubin's knowledge is very easy to understand, even if it is very cutting-edge knowledge, it will not make people feel obscure at all.

"With regard to quantum computers, we now have two main research directions."

"The first direction is optical quantum computers. For example, Jiuzhang No. 2 can solve specific problems at a speed billions of billions of times faster than that of classical computers."

"This type of quantum computer has the advantages of fast calculation speed and relatively low energy consumption, but so far, it cannot be universally programmed."

"The second direction is superconducting quantum computers. For example, Wenyuan-2, the calculation speed of specific problems is 10 million times that of the fastest classical computer."

"Although the computing speed is not as exaggerated as the optical quantum computer and requires more energy consumption, it can be programmed universally and is more practical."

Hearing these terrifying numbers, Xu You also found it hard to imagine.

Whether it is 10 million times or billions of times, it sounds like a huge number.

"So far, China is the only country that has achieved quantum superiority in the fields of superconducting qubits and optical quantum. Such an achievement is enough to inspire us. But we must also admit that all current quantum computers cannot really enter the On the road to practical application. There are even some civilian scientists who believe that the entire field of quantum computers is just a hoax.”

Hearing this, the people in the conference room couldn't help laughing at themselves.

For this kind of sound, many researchers have actually experienced it.

What is the use of these things you have studied?

Since it is useless, and it needs to spend such a high amount of money for research, it is better to donate the money to the poor people at the bottom so that they can live a better life.

But in fact, before each technology is officially applied, no one can guarantee how much application value it will have.

If you give up research because you are worried that it has no application value, then the technological level of the entire country will never develop.

"To be honest, I don't dare to guarantee 100% that quantum computers will have great application significance in the future. But I am still quite confident that within four to five years, quantum computers will be able to enter the initial practical application in China. phase."

"Of course, this also requires the joint efforts of many scientific researchers. Everyone here, the research field is related to quantum computing. If you want to, you can join the 'Sea Island' quantum computer project."

Hearing about the new project "Sea Island", everyone's attention became more concentrated.

"The 'Sea Island' quantum computer is China's next quantum computer project, and it strives to create the world's first quantum computer that can be put into practical use. It will require a lot of technology, and professors who are willing to join the project , after the meeting, you can come to the front and sign your name. After that, we will draw up a general direction for each experimental group."

"The improvement of China's technological level requires our joint efforts. I hope that one day, we will truly stand on the top of the world's technology."

After listening to this meeting, most of the participating scientific researchers have a positive attitude towards participating in the "Sea Island" project.

On the one hand, everyone hopes that they can make their own contribution to the country's cutting-edge technology.

On the other hand, as a scientific researcher, who doesn't want to take on more projects.

What's more, it is such a national project.

No matter from which point of view, this is a very worthwhile thing to join.

After discussing with the people around him, Wang Xiangwu also decided to join the "Sea Island" project.

Like Wang Xiangwu, many professors stepped forward to sign their names.

When Wang Xiangwu came back, Xu You found that there was someone he knew beside him.

It was Professor Johnson.

Wang Xiangwu was about to introduce Qiao Sen to Xu You, but Xu You took the lead and said, "Mr. Qiao, are you here too?"

"Haha, Xu You, I didn't expect you to be here today. You should be the youngest in the entire venue today, but your contribution to the "Sea Island" project in the future may be very great."

Seeing the scene where Qiao Sen and Xu You talked freely, Wang Xiangwu questioned:

"Why, you two have known each other for a long time?"

"Well, when Xu You participated in the Wujing training camp, there was a problem that used the advanced solution of Mathematics Competition. Cao Quanli didn't answer it correctly, so he asked me to take a look. At that time, I thought this child was very unusual. I didn't expect that later , Xu You not only won the first place in IPhO, but also published a paper on PRL so early. Sure enough, my vision is all right."

"Haha, I still want to introduce you to Xu You, it seems unnecessary. Let's go, let's go have a meal together."

"Okay, then I'll call the people in our group too. This time, I'll invite you!"

"Hey, how can I do it, please, please!"

Zhao Weijia and Xu You, who had a meeting with Wang Xiangwu, were naturally called to the dinner.

Except for Zhao Weijia and Xu You, the rest are basically professors and associate professors of Ji University.

Xu You really didn't know what to say in front of the professors, so he could only nod and smile apologetically.

Fortunately, there are people like Zhao Weijia, who are also juniors, accompanying Xu You, so that Xu You will not feel too lonely.

At the dinner table, the professors talked about the meeting just now and the "Sea Island" quantum computer project.

"I didn't expect that the Chinese Academy of Sciences would undertake such a big project this time. It seems that we really have to make up our minds to put quantum computers into practical use."

"To be honest, I think the previous few quantum computers are really of little practical significance, but they cost a lot of money. I don't know if they can come up with something this time."
