Chapter 236 Feed the food directly to your mouth

Classroom.

Professor Zhong noticed that Deng Ziyi's expression seemed a little wrong, so he asked with a smile: "Xiao Deng, do you have anything to add?"

Before Deng Ziyi spoke, Xu Qingzhou smiled. Said: "If it is about the accuracy of the density matrix, then there is no need to think about it."

"I have studied the density matrix by the way in the past two days and found that due to the cumulative error and rounding error of numerical calculation, As a result, the density matrix failed and the data accuracy was very poor, so I came up with a solution. Professor Zhong, you can take a look first.”

Professor Zhong and the three of them were stunned for a moment, even wondering if they had heard wrongly.

What the hell, the density matrix problem has also been solved?

"Xiao Xu, you mean that after solving the quantum decoherence problem, you also studied the density matrix, discovered the accuracy problem, and then solved it?"

Professor Zhong He came back to his senses and asked firmly.

Xu Qingzhou pointed to the manuscript paper on the table: "Well, the stack of manuscript paper on the left of Senior Brother Wan is the solution."

Wan Hao quickly handed the manuscript paper to Professor Zhong, and stood behind Professor Zhong with Wang Yigui, looking at the calculations on it together.

First, use Chebyshev polynomial expansion.

[H=\frac{\hbar\omega}{2}\sigma_z]

After this, parallel computing and distributed computing technology are used to accelerate the calculation process.

【[\sigma_z\0&-1\end{pmatrix}]】

After 10 minutes.

Professor Zhong put down the manuscript, took a long breath, looked at Xu Qingzhou with a complex expression, his throat moved, and he didn't know how to describe this young man.

Xu Qingzhou is very talented in physics and can be said to be an expert in mathematics.

However, the impact of this incident was so great that he felt in a trance.

I was just lamenting that Xu Qingzhou solved the quantum decoherence problem in two days.

As a result, it turned out that they had even solved the second problem.

Wan Hao stared at the manuscript paper in his hand: "Chebyshev polynomials, why didn't we consider this before? Junior brother, how did you think of using this method?!"

"I was lucky. I planned to give it a try at that time, but I didn't expect it to actually work." Xu Qingzhou remained modest.

“.”

The classroom became quiet, and Professor Zhong’s expressions became even stranger.

Is quantum decoherence a matter of luck? Is the density matrix also a matter of luck?

The first time can be said to be luck. If they still believe it is luck the second time, unless they are fools.

Beyond the surprise, there was also a trace of inexplicable flavor in this man's humility.

It’s hard to describe the smell. In short, it makes people want to punch this unpunchable face.

Oh~

They thought of another big question: had the two hard-to-gnaw bones that were causing them great distress in the morning actually been chewed?

I was surprised and thought this was too weird.

Deng Ziyi sighed repeatedly in her heart. When she saw Professor Zhong showing the same expression as before, she thought happily: Look, even the professor and the others were shocked.

Professor Zhong took a deep breath to calm down, looked at the two dark circles on Xu Qingzhou's eyes, and thought for a moment, "Xiao Xu, you must be very tired these two days. Go to the dormitory to rest first. I Go through these two options with Xiaohe and the others."

Xu Qingzhou had no objection, nodded and said with a smile: "If you have any questions, you can call me."

I stayed up until four o'clock and got up at around 7 o'clock today. Now my body has begun to protest, signaling that I need to rest after bursts of exertion.

After giving all the manuscript papers to Professor Zhong, Xu Qingzhou nodded to Wan Hao and others, and went to the dormitory with his schoolbag.

There are only four people left in the classroom.

Looking at the two thick stacks of materials on the table, Professor Zhong fell silent again. I don’t know why, but now he suddenly recalled a sentence he said to the students before: I have already fed you the food. Bian, bala bala.

Thinking of this, Professor Zhong couldn't help but smile to himself. He, a dignified professor from the University of Science and Technology, actually felt like being fed.

Even chewed up and fed.

A bit outrageous.

Besides, Wan Hao and Wang Yigui had similar thoughts to Professor Zhong. This matter is really unbelievable. Can one person really defy nature to such an extent?

Let’s cheat!

We only have 24 hours in a day, and this junior brother has 48 hours.

Wan Hao, in particular, was a little skeptical when he first heard Xu Qingzhou say that it might be possible to solve the quantum decoherence problem.

I am impressed now.

It can only be said that there are no empty scholars under the great reputation.

“Everyone, stop standing around and start working.” Professor Zhong clapped his hands and sighed with emotion. It was a good thing to be able to finish something so quickly that was originally planned to take two weeks.

Wan Hao and the other two nodded and began to check the density matrix, while Professor Zhong was mainly responsible for determining the quantum decoherence plan.

Deng Ziyi followed Professor Zhong doing odd jobs.

Just when the four of them started to get busy, Xu Qingzhou had already returned to the temporary dormitory, set an alarm clock for 12 o'clock, and fell asleep.

11:40 noon.

Before Xu Qingzhou woke up, Professor Zhong arrived at Academician Ma Zailiang’s office with two documents.

"Professor Zhong." Academician Ma smiled softly, waved for Professor Zhong to sit down first, and poured him a cup of tea.

Professor Zhong sat down and said directly: "We have solved the problems of quantum decoherence and density matrix."

"Huh?" Academician Ma was stunned for a moment and paused. After a pause, he said with a little emotion: "Sure enough, with Mr. Su, everything is not a problem."

Professor Zhong shook his head and said with a bitter smile: "You misunderstood, the person who can solve these two problems is not The teacher is Xu Qingzhou, a member of our group.”

“Xu Qingzhou?”

Academician Ma paused while drinking tea, a little unresponsive.

“Yes.”

Professor Zhong’s eyes were full of admiration and he said: “The solutions to quantum decoherence and density matrix were all thought up by Xu Qingzhou.”

"."

After reading both documents, Academician Ma exhaled, "This kid is really unexpected. It seems that I was right to pull him here."

"Among the young people I have seen, Xu Qingzhou's talent in physics is definitely the strongest." Professor Zhong said.

"Yes, our Xia Kingdom's physics community will have a new star in the future."

At noon, Xu Qingzhou got up on time, sent a message to Song Yao, then went to the cafeteria to eat, and then Return to the laboratory.

Professor Zhong and the others haven’t left yet.

Professor Zhong said with a smile: "Xiao Xu, we have checked both of your plans. There is no problem, and they are also very efficient. They are not only suitable for medium and low orbit quantum satellites. If you change it, I and I will Academician Ma believes that it can even be used on future high-orbit satellites.”

"As long as it works." Xu Qingzhou said to himself that these things were really pulled from medium and high orbit satellites, and they were considered weakened versions.

"Junior brother, you are awesome." Wan Hao expressed his admiration for Xu Qingzhou simply and clearly.

Xu Qingzhou smiled modestly.

The two stumbling blocks are gone, and the next step is the follow-up calculation.

But it only started in the afternoon. Professor Zhong and the others went to eat. Xu Qingzhou had nothing to do, so he simply took out two pieces of guessed information from his bag and spent noon reading the information.
