My science and technology museum

As the saying goes, if you want to do your job well, you must first sharpen your tools. Seeing how interested everyone was in this virtual model, Xu Lei decided to postpone the manufacturing of the quantum computer until tomorrow.

This will give everyone enough time to study the core model of quantum computers.

In this way, when you actually get started, I believe it will reduce a lot of mistakes and speed up the project progress.

Xiao Chengyong, Yuan Zhi and others were naturally overjoyed.

The opportunity to improve one's own research level in the quantum field is something that cannot be obtained in the top overseas quantum laboratories.

Then I was so immersed in it that I didn't even bother to eat.

Faced with this situation, although Xu Lei was a little bit dumbfounded, he also understood the desire of scientific researchers for knowledge and technology.

However, for the sake of their health, Xu Lei still ordered the restaurant to send the meals directly to the data center.

As everyone continued to study the model in depth and verified the feasibility of its theory through Xingpu, their admiration and admiration for Xu Lei became more profound.

It is unimaginable that Xu Lei can study quantum computing and quantum communication to this extent in his spare time. I am afraid that if we look at the development of science and technology in the world for so many years, it will be difficult to find someone who can compare with him.

It will be included in the textbook in the future.

"A refrigerator that does not require liquid helium to assist in cooling can run continuously for a long time. This alone solves one of the biggest problems of quantum computers."

"There is also the design of microwave equipment to control quantum gates, which is a completely new concept."

"How do you think the dean's head grows? It's really different from person to person!"

While Xiao Chengyong, Yuan Zhi and others were talking and discussing with each other, Gu Sanlin was also not idle.

Although he said that his main research field is special materials, which is not too close to the technical knowledge in the quantum field, many of the refrigeration systems and other core components of quantum computers require the use of very special materials. It can be said that his The task is equally heavy.

So taking advantage of this time, he took the initiative to communicate with Xu Lei.

I hope I can get some inspiration from Xu Lei.

Xu Lei is naturally not stingy about this. After all, the role of materials is also crucial.

If the material problem can be further overcome, it will not only be more conducive to the manufacture of quantum computers, but will also inevitably lead to qualitative changes in many other industries.

that's all.

Time passed quickly in the atmosphere of curiosity.

The next day.

Just after dinner in the morning, everyone came to the data center quantum computer laboratory again.

Quantum computers are completely different from traditional terminal equipment. If you want to manufacture them, the first thing to solve is the core of the refrigeration system and the superconducting quantum chip inside.

Building a more powerful dilution refrigerator is the first step.

The quantum state is extremely susceptible to interference from the external environment. To ensure the stability of the quantum state, it must be placed in a special environment with low temperature, noise, and no interference from external factors. Whether this step can be successful or not is related to the ultimate success of this quantum computer. What is the performance like?

"Dean, everything is ready and you can start."

At this time, as Yuan Zhi finished reporting the situation, the hearts of other project members wearing operating uniforms around him suddenly jumped a few times.

I can't hold back the eagerness in my heart.

After careful study and discussion of the virtual model drawn by Xu Lei yesterday, everyone is full of confidence at this moment.

They all want to quickly get started and verify their theoretical results.

Upon hearing this, Xu Lei focused his attention on a pile of materials and equipment not far away. Among them, a long white barrel that seemed to be almost two meters in diameter was the most conspicuous.

As the shell of the entire refrigeration system, its core and superconducting quantum chip must be installed inside.

Therefore, its performance has become extremely important. If you want to be as completely noise-free as possible without being disturbed by external factors and ensure the stability of the quantum state in the barrel, its material needs to be constantly experimentally replaced.

Find the best solution.

As for the refrigeration system shell in front of me, it was customized through normal channels.

Will be used in preliminary experiments.

After all, for such a sophisticated and huge physical device, even if Xu Lei had all the technical knowledge in his mind, he would not be able to successfully assemble it for the first time.

Yesterday, he pointed out the correct research direction for Gu Sanlin, asking him to lead the team to develop a special metal composite material suitable for use as the casing of the refrigeration system, and re-manufacture the casing according to this specification.

It is also worth mentioning that compared with quantum computers in other quantum laboratories at home and abroad, the Longhu Light is larger in size.

Once it is all manufactured, I believe it will have a very visual impact.

Seeing that everything was ready, Xu Lei naturally would not waste any more time. After confirming that there were no problems in all aspects, he immediately responded: "Then let's officially start."

The words just fell.

The project members came to their respective work stations and started taking action in accordance with the previously assigned tasks.

Create this refrigeration system that does not require liquid helium to assist cooling.

Since Longfor Light uses an ultra-low temperature control chip, which reduces the circuit distribution to a certain extent and avoids heat generation as much as possible, its core is much thinner than other lampshade-like shapes, and it is also more sophisticated and complex.

However, this ultra-low temperature control chip is not yet in place, and the quantum chip Xu Lei wants also requires special production processes.

It cannot be installed on the kernel in a short period of time.

Therefore, according to Xu Lei's plan, other structures of the refrigeration system should be completed first.

Then while waiting for the chip, we can develop the most important quantum algorithm.

For a computer to function properly, it must be able to correct small, random errors at any time.

In a quantum computer, such errors can come from faulty circuit components or interactions between the qubit and its surroundings.

Once these problems occur, the coherence between qubits will quickly disappear, so the calculation time must be shorter than this time, and if these random errors are not corrected, the calculation results of quantum computing will be worthless It can be said.

The mathematical principles behind quantum algorithms are clear, but the technology faces huge challenges.

What Xu Lei has to do is to overcome this challenge.

Although there are great difficulties, Xu Lei believes that with his own mastery and technical means and the assistance of Xingtong, he will be able to perfectly overcome this problem.

Time cannot be grasped or touched.

But you can feel it.

When I go to school, I always look forward to getting out of class as soon as possible. The forty minutes feel like a year.

From time to time he looked up at the clock on the wall.

You will wonder why time is so slow.

But the dozens of days of vacation were over before I had much fun.

Especially after I grow up and leave school and enter the society, when I look back on my childhood memories, I realize that twenty years is just a blink of an eye.

For the members of the Longfor Light project team, they are fully devoted to the research and development of quantum computers and can hardly notice the passage of time.

soon.

The time has come to the second half of the year.

As Pingguo frequently increases its publicity in the Asian market, carbon-based chip mobile phones have entered the field of vision of more people.

Although the performance of silicon-based chips is sufficient for daily use in most situations, it is still quite tempting for those who like to pursue cutting-edge products.

The key selling price has not yet increased with the cost of carbon-based chips.

It is really cost-effective.

Although this phone is not equipped with a solid-state battery, because neither Huawei nor Xiaomi will release new models online in the second half of this year, there are not many people willing to buy it.

It can be predicted that after this mobile phone is officially sold, there is a high probability that it will regain the sales champion position in the high-end mobile phone market in the sub-region.

And as the official launch of the mobile phone gets closer and closer, there are gradually more and more relevant comments on domestic website platforms.

Among them, there are some bloggers with millions of fans who are collectively known as Chapingguo.

This was basically impossible to see before.

It can only be said that Pingguo really attaches great importance to the Asian market this time.

We must suppress Warwick again at any cost.

On the other hand, in terms of future technology, since the official announcement of quantum computer research, no one has continued to pay attention to it.

Almost no one talks about it anymore.

The main reason is that no one believes that future technology can create a real quantum computer and commercialize quantum computing.

However, another incident that occurred during this period caused considerable discussion in the country.

That is, as the world's richest man, Marsne launched rockets multiple times in two months to put a large number of satellites into orbit to speed up the layout of the Starlink project.

Although the Starlink project is said to provide satellite broadband services, it can also be of great help in the military.

Coupled with the many Starlink schematics circulated on the Internet, seeing the massive satellites surrounding the entire Blue Star, I felt my scalp numb and a strong uneasiness welling up in my heart.

"Is Masen planning to give up on Tesla completely and just put it aside to launch satellites?"

"Who knows how awesome the technology is? It can send dozens of satellites to the sky at a time. Thinking that there will be thousands or even tens of thousands of satellites forming this star chain, I feel deeply worried."

"I heard that this Starlink almost touched our space station several times."

"Truss was forced to withdraw from the sub-regional market by Xingyuan Motors. Even its own super factory was taken away by others. Why is there no response? I always feel that this overseas old horse is holding back something bad."

"What's wrong with the world's richest man? Now anyone who wants to engage in future technology must think twice."

"If Future Technology hadn't spent crazy money in the past two years and couldn't recover profits in the short term, Mr. Xu would have been the richest man in the world."

…

Naturally, Xu Lei didn’t pay much attention to the online discussions about Starlink and future technology.

Because after several months of hard work, the ultra-low temperature control chip and quantum chip were finally in place. Even Gu Sanlin's research on special metal composite materials has made breakthrough progress, and he successfully used this material to create a new refrigeration system casing.

For this reason, Xu Lei deliberately stopped the development of quantum algorithms and decided to assemble and test this new system.
