As a programmer, it is obviously abnormal to have thick hair.

It is even easy for people to think that this is a programmer who is not capable enough.

Of course, every programmer doesn't want to do this, it's just a helpless result because of the work he is doing.

Xu You recalled the various hair loss phenomena he had seen in these years, and felt that the focus was not on the profession of programmers, but on the habits of this profession.

"Chang Gong, do you stay up late every night?"

"Let's put it this way, Xu You, have you ever seen Jijing at four o'clock in the morning?"

"Rarely, my work and rest are relatively regular." Xu You said.

"At this time of day, I haven't got off work yet." Chang Xiaoping said with a smile.

"Then Chang Gong, do you usually exercise?"

"I also exercise. When I am resting, I will engage in some e-sports and the like."

"Is the diet regular?"

"This is quite regular. I have supper every night, and coffee is even more essential."

Hearing what Chang Xiaoping said, Xu Youxin said, it's no wonder that she doesn't lose her hair.

"Chang Gong, if you can go to bed early and get up early, eat three meals a day, exercise regularly, and drink plenty of hot water, you shouldn't be in this situation."

"Forget it, I can't do it. It's more realistic to find a good hair transplant doctor."

"It just so happens that my senior brother has had hair transplanted. I'll ask you when I get back."

During the conversation between the two, Chang Xiaoping had already finished copying the data for Xu You.

In the following days, Xu You started the analysis of the original modeling and simulation structure, as well as the actual measurement of the crosstalk part.

The structure of this part includes dielectric substrate, superconducting layer, vacuum part, control line and so on.

And there are many properties that are involved and need to be measured.

For example, the electrical insulation properties of dielectric materials, spatial structure, chemical properties, dielectric constant and so on.

In the part of superconducting materials, in addition to the accurate setting of superconducting critical temperature, the setting of electrical conductivity and magnetic permeability of superconducting materials is also a key issue.

Because in theory, after the superconducting material enters the superconducting state, the theoretical superconducting conductivity is infinite and the magnetic permeability is 0.

But in practice, both the conductivity and the magnetic permeability will have a specific value and have certain fluctuations.

It is very difficult to carry out accurate modeling and simulation.

During this period, Xu You repeatedly carried out the work of measurement, modeling and adjustment, and communicated with Han Shubin and Chang Xiaoping many times.

With the joint efforts of Xu You, Han Shubin, and Chang Xiaoping, the modeling and simulation of the crosstalk part was finally completed.

After completing this part of the modeling work, the team began to conduct crosstalk simulation tests.

In addition to Xu You, Han Shubin, Chang Xiaoping and others also participated in the simulation experiment on the spot.

"Academician Han, Chang Gong, after many times of debugging and comparison, the final simulation value of conductivity is 1.26×10^10 S/m, and the simulation value of magnetic permeability is 9.38×10^(-9) H/m. Now let's simulate separately the influence of excitation on different ports on the three control lines."

"Okay, Xu You, please start your test."

Xu You first excites port 1, and closes ports 2 and 3 at the same time, and simulates the magnetic fields on these three control lines through simulation modeling.

Following Xu You's operation, various data on the three detection lines appeared simultaneously on the screen.

By observing the magnetic field at the location of the Josephson junction.

It can be seen intuitively that the crosstalk isolation between every two control lines.

"It's so accurate!"

After seeing the data on the screen clearly, Han Shubin couldn't help exclaiming.

The simulated value of the crosstalk isolation in Xu You's model differs very little from the measured value through previous experiments.

Chang Xiaoping also opened his mouth in surprise after seeing the data.

As a top programmer, Chang Xiaoping knows how difficult it is to simulate this model accurately.

This requires not only solid computer knowledge, but also the mastery and application of quantum physics, electromagnetism and other knowledge very skillfully.

In order to further verify the accuracy of the model and avoid accidents, Xu You then excited ports 2 and 3.

Similarly, the crosstalk isolation simulated twice is also very close to the actual measured value.

Seeing such a result, the whole lab was very excited.

"After exciting the three different ports, the data obtained are very accurate, which basically confirms the accuracy of this set of simulation modeling. Xu You, fortunately, I found you, and I know that my choice is not right. will be wrong."

Han Shubin praised Xu You in front of the whole lab.

At this time, the entire laboratory staff admired Xu You so much.

Before this, they had all heard about Xu You's ability, but they had never witnessed Xu You's power with their own eyes.

Some people even have doubts about Xu You's ability because of Xu You's age, thinking that Xu You has only made some theoretical achievements, and is not as amazing as in the legend.

This time, they will never question Xu You again.

Of course, Han Shubin deliberately said these words in front of everyone, not only because he was in a good mood, but also to help Xu You establish a position in the project team.

Otherwise, some people would really think that Xu You just came here for an internship.

In Han Shubin's heart, although Xu You is not the core pillar of the island plan.

But it is definitely the key to success.

Han Shubin admitted in his heart that even if he was a talent like Xu You, he couldn't compare with him.

"Academician Han, next I want to continue to optimize this set of simulation modeling, and then conduct research on improving the isolation."

Xu You's expression was very calm, and he was not very happy with the results of the first version of simulation modeling.

This is like a very difficult mock exam with a perfect score of 100, but only 95 points.

Although it may be ranked first, there is nothing to be happy about, but you should think about how to continue to improve.

After all, there is still a lot of room for improvement.

After two optimizations and improvements, Xu You was finally basically satisfied with this set of simulation modeling.

The next question is how to suppress the magnetic field crosstalk and improve the isolation of crosstalk.

After in-depth thinking, Xu You determined the main problem.

To put it bluntly, this is a question of electromagnetism.

Because the current has a magnetic effect, when a current is passed through a control line, a magnetic field will be generated, thereby affecting other control lines.

Of course, although the principle is easy to understand, it is not so simple to solve this problem well.

How to adjust the direction of the current to reduce the degree of crosstalk as much as possible is a very complicated knowledge.
