Start as a top student and move towards the stars and the sea

"Qi Wan...is also involved in this project?"

Ning Chen was not too surprised by Ren Mingshan's joining. After all, Ren Mingshan was also an expert in quantum physics, so it was reasonable to join the research in this project.

But Ning Chen was somewhat unexpected that Qi Wan's learning also appeared in the project team.

"rather……"

After Qi Wan recognized Ning Chen's identity, she was so surprised that she almost blurted out Ning Chen's name, but she still held it back.

This kind of occasion is very serious. Qi Wan does not dare to yell casually. No matter how many questions Qi Wan wants to ask Ning Chen, they have to wait until the meeting is over.

Ning Chen gave Qi Wan a look, and Qi Wan nodded slightly, indicating that she understood what Ning Chen meant.

Ning Chen thought for a moment and felt that the addition of Ren Mingshan, Qi Wan and others was understandable.

The people who went to the Chinese Academy of Sciences for meetings before were only representatives from various laboratories. In fact, there must be more people involved in the experimental work.

Although Qi Wan is just a student, her scientific research ability is very strong after all, and she would not even belong to some university teachers who have just stayed in school.

In the following time, the person in charge of the Yanda Experimental Group explained to everyone the progress of the current project and some problems that had arisen.

"One of the main problems here is the problem of error correction in the quantum computing process. Because the principles of quantum computers and traditional computers are different, including the use of check bits, check codes and other traditional computer error correction methods, in quantum computers It doesn't work on computers..."

Ning Chen is also aware of these things, and because quantum computers are very sensitive to the environment, errors occur more frequently than traditional computers.

If the problem of quantum error correction cannot be solved, the quantum computer will not be able to work stably. No matter how fast the calculation speed is, the calculated results will be meaningless.

"Our current approach to solving this problem is to start from several aspects such as the stability of qubits, the accuracy of quantum gate operations, and the control of quantum entanglement. However, it is not easy to achieve these, and many technical difficulties need to be solved. We We are also working hard to solve these problems one by one.”

After hearing about the experimental team's current project progress and various problems encountered, Ning Chen was also thinking about something.

Ning Chen knew that the experimental team at Yanda was unable to solve these problems in a short period of time, not because the experimental team at Yanda was not capable enough, but because these problems were indeed very complex.

Yanda's physics department has reached the top level in the country. Even the best foreign laboratories may not be able to solve these problems in the same time.

The experts from the Chinese Academy of Sciences were discussing various issues with the experts from Yanda University. When Ning Chen saw this, he quietly slipped to Qi Wan's side.

"Qi Wan, tell me about some more specific situations in the project."

Seeing Ning Chen coming suddenly, Qi Wan was not prepared at all, and asked curiously:

"Ning Chen, how did you get involved in this project?"

"We'll talk about this later. Answer my question first."

After all, Ning Chen came to Yanda this time as an expert from the Chinese Academy of Sciences, so Qi Wan had no choice but to answer obediently.

Compared with Teacher Yan's more official answer, Qi Wan's answer is much more practical.

"These problems are really difficult to solve. We have used almost every method we can think of, but none of them have been able to solve these problems well. In fact, some teachers behind the scenes feel that these problems cannot be solved in a short time. fixed……"

From Qi Wan's words, Ning Chen learned that the current teachers at Yanda do not have a too positive attitude towards current research.

Of course, this does not mean that they are treating research negatively, but when they have no clue about research, they can only try blindly.

This is a relatively inefficient research method, but Ning Chen also knows that it is really difficult for them to come up with a better method at this time.

At this time, Ning Chen was a little lucky that he did not keep waiting. Otherwise, even in the past few months, it would be difficult for the project to make significant progress.

However, Ning Chen did not feel desperate because of this. In fact, Ning Chen already had a basic solution in mind.

"Okay, we basically understand the current status of the project."

After chatting with the majors from Yanda for a long time, Yue Jiafeng said with a serious expression.

As an expert in quantum physics, Yue Jiafeng knows how difficult these problems are.

Moreover, these results cannot be directly copied back to the Chinese Academy of Sciences for research like the system previously developed by Shuimu University.

When Yue Jiafeng was debating whether to go back to the Chinese Academy of Sciences now, he saw Ning Chen quietly coming to his side and whispering something to him.

"Teacher Ning, can this plan really work?"

"I'm at least 80% sure, and I suggest you give it a try."

Yue Jiafeng hesitated for a moment, then nodded.

Yue Jiafeng cleared his throat and said to everyone:

"I think we can protect quantum information from interference from the external environment through quantum error correction codes."

After hearing Yue Jiafeng's words, everyone subconsciously turned their attention to Yue Jiafeng.

At this time, Yue Jiafeng actually felt very guilty, because even Yue Jiafeng himself was not sure whether this plan would really work.

But out of his trust in Ning Chen, Yue Jiafeng didn't show any timidity on his face, but showed a confident attitude.

As he got closer, Yue Jiafeng repeated the ideas that Ning Chen told him just now to the others.

Yue Jiafeng's words obviously frightened others, and these ideas had some theoretical support, which made others feel the hope of this plan.

At this time, a professor from Yanda University asked:

"Academician Yue, the operating mode of quantum computers is different from traditional computers. We cannot simply encode and decode logical qubits, but we must also use them to perform calculations. In the specific implementation of the plan, we How should this problem be solved?”

Hearing the professor's question, Yue Jiafeng was speechless for a moment and didn't know how to answer.

After all, the time just now was relatively limited, so Ning Chen only told himself some basic ideas of the plan, and did not explain every detail in detail.

However, Yue Jiafeng still maintained a very calm state, pretending to be nonchalant and said:

"This is not a completely unsolvable problem. Teacher Ning, please give them the answer."

Ning Chen heard the words and immediately took over the words and said calmly:

"Yes, as Academician Yue said, this is not a completely unsolvable problem. Simply put, as long as we find a relatively simple and low-cost logic gate technology, it can help us complete these tasks... …”

While talking, Ning Chen drew the quantum logic gate in his mind on the blackboard in the laboratory, as well as the editing ideas of the quantum error correction code.

Listening to Ning Chen's explanation, many experts gradually understood Ning Chen's ideas and realized that this was indeed a plan that could be tried.

After finishing his thoughts, Ning Chen did not forget to glance at Academician Yue.

Yue Jiafeng looked at Ning Chen gratefully. If Ning Chen hadn't taken over his words just now, then he would really be in trouble.

"I wonder if everyone understands it. Do you have any other opinions about this plan?" Yue Jiafeng asked.

In fact, at this time, Yue Jiafeng really understood it. Yue Jiafeng believed that other experts should have almost understood Ning Chen's thinking.

"I understand, Academician Yue, your idea is indeed very novel and unique. I think we can really try it."

"I support the proposal of Academician Yue and Teacher Ning. If we can compile a set of useful quantum error correction codes together, it will undoubtedly greatly improve the stability of quantum computers and maximize the accuracy and reliability of the quantum computing process. degree."

Ren Mingshan also expressed his support for this plan. Among the experimental team of Yanda, Ren Mingshan still has a high say.

With everyone's joint support, the project team decided to optimize the project according to this idea.

After the entire idea was clear, Ning Chen no longer needed to do everything. The project team could continue the optimization work in an orderly manner.

At some point, Qi Wan came to Ning Chen and whispered:

"Hey, Ning Chen, what are you responsible for in the project?"

Through his own observation just now, Qi Wan always felt that Ning Chen was not just an expert on the expert team.

Qi Wan always had a feeling in her heart that even compared to Yue Jiafeng, Ning Chen played a more important role in the project team.

Ning Chen saw that Qi Wan had already guessed something. Although this girl usually seemed carefree, she was actually extremely thoughtful.

Ning Chen made a "shh" gesture with his finger, and Qi Wan immediately expressed his understanding and stopped asking any more questions.

In the next few days, Yue Jiafeng, Ning Chen and others will come to the Yanda Physics Laboratory every day to optimize the project with everyone.

After everyone's joint efforts, the project team successfully edited a set of quantum error correction codes. After testing, this set of quantum error correction codes is undoubtedly very successful.

After adding quantum error correction codes, the entire quantum computing system can detect and process errors in quantum computing in a timely manner, greatly improving the accuracy and reliability of quantum computing.

This also solved the problem that had troubled the Yanda physics experimental group for many days.

The teachers at Yanda are also convinced by this result.
