Chapter 236: Directly feed the rice to your mouths

Classroom.

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

Before Deng Ziyi could speak, Xu Qingzhou said with a smile: "If it's about the accuracy of the density matrix, then you probably don't need to think about it either."

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

Professor Zhong and the three were stunned for a moment, even doubting if they had misheard.

What the hell, the density matrix problem is also solved? "Little Xu, do you mean to say that after solving the quantum decoherence problem, you studied the density matrix by the way, discovered the accuracy problem, and then solved it?"

Professor Zhong recovered and asked definitely.

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

After reading the two sets of materials, Academician Ma exhaled, "This child is really unexpected. It seems it was right to pull him over at the beginning."

Read! {

This taste is hard to describe. In short, it makes people want to punch this annoying face hard.

"."

"."

Wan Hao stared at the draft paper in his hand: "Chebyshev polynomial, why didn't we consider this before? Xu Xu Shidi, how did you think of using this method?!"

Professor Zhong put down the draft paper, exhaled a long breath, and looked at Xu Qingzhou with a complex expression. His throat moved, and for a moment he didn't know how to describe this young man.

Even the kind that is chewed up and fed.

Xu Qingzhou is talented in physics, and can be called an expert in mathematics.

"Everyone don't stand, start working," Professor Zhong clapped his hands. Emotion aside, being able to finish what was originally planned to take two weeks so quickly is a good thing.

Xu Qingzhou hadn't woken up yet, Professor Zhong took two documents to Academician Ma Zailiang's office.

Thinking of this, Professor Zhong couldn't help but laugh at himself. He, a dignified professor of the University of Science and Technology, would also have this feeling of being fed rice.

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

10 minutes later.

At noon, Xu Qingzhou woke up on time, sent a message to Song Yao, then went to the canteen to eat, and then returned to the laboratory.

Professor Zhong said with a smile: "Little Xu, we have verified both of your plans, no problem, and they are very efficient. Not only are they suitable for medium-to-low orbit quantum satellites, but after some modifications, Ma Academician and I both think they can even be used for future high-orbit satellites!"

Especially Wan Hao, who was a bit skeptical when he first heard Xu Qingzhou say he might be able to solve the quantum decoherence problem.

Professor Zhong sat down and said directly: "Regarding the problems of quantum decoherence and density matrix, we have already solved them."

Staying up until four o'clock, he got up at seven or eight today, and now his body has begun to protest, sending signals that he needs to rest after exhaustion.

"Professor Zhong." Academician Ma smiled lightly, waving his hand to signal Professor Zhong to sit down first, and poured him a cup of tea.

11:40 AM.

!.

Looking at the two thick stacks of materials on the table, Professor Zhong fell into silence again. I don't know why, but now he suddenly recalled a sentence he said when teaching students before: I have already fed the rice to your mouths, *ba la ba la*.

Wan Hao and Wang Yigui had similar thoughts to Professor Zhong. This matter is truly a bit bizarre. Can a person really be against the sky to this extent? Cheating! We only have 24 hours a day, this Xu Xu Shidi has 48 hours.

Professor Zhong and they hadn't left yet.

First, use Chebyshev polynomial expansion.

Professor Zhong's eyes were full of appreciation, saying: "The solutions to quantum decoherence and density matrix were all thought of by Xu Qingzhou."

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

It is both a surprise and feels that this matter is too weird. Wan Hao hurriedly handed the draft paper to Professor Zhong, and he and Wang Yigui stood behind Professor Zhong, looking at the equations above together.

"Luck is good, I planned to try it at the time, but didn't expect it to really work." Xu Qingzhou remained modest.

"It can be used," Xu Qingzhou thought to himself that these things were really dug out from medium-to-high orbit satellites, which counts as a weakened version.

Deng Ziyi sighed repeatedly in her heart, seeing the expression on Professor Zhong's face that was the same as her own earlier, and thought happily: Look, even the professors were stunned.

It can only be said that there is no false scholar under the name.

But the impact of this matter was really too big, which made him have a feeling of being dazed.

Deng Ziyi followed Professor Zhong to do odd jobs.

Just sighing that Xu Qingzhou solved the quantum decoherence problem in two days.

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

Professor Zhong took a deep breath to calm himself down, looking at the two dark circles on Xu Qingzhou's eyes, thought for a while, "Little Xu, you must be very tired these two days, go to the dormitory to rest first, I and Little He and the others will go through these two plans."

The classroom quieted down, and Professor Zhong and the others' expressions became even stranger.

Xu Qingzhou had no opinion, nodded, and said with a smile: "If there are any problems, you can call me."

Academician Ma's hand holding the tea paused, a bit unresponsive.

Beyond surprise, in his modesty, there was a taste that was unclear.

Is quantum decoherence luck, and is the density matrix also luck?

*Whoa*~ They thought of another big problem: the two hard bones that were making them extremely distressed in the morning had actually been gnawed by someone?

【\sigma_z\0&-1\end{pmatrix}】

"Hmm?" Academician Ma was stunned for a moment, paused, and sighed with some emotion, saying: "Sure enough, with Su Lao, everything is not a problem."

Wan Hao and the two nodded, and began to verify the density matrix part, while Professor Zhong was mainly responsible for the determination of the quantum decoherence plan.

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

A bit outrageous.

As a result, it turned out that people had already solved the second problem.

【h=\frac{\hbar\omega}{2}\sigma_z】

Professor Zhong shook his head and smiled bitterly: "You misunderstood, the person who solved these two problems is not the teacher, but Xu Qingzhou, a member of our group."

Now convinced.

Handing all the draft paper to Professor Zhong, Xu Qingzhou nodded to Wan Hao and the others, carrying his schoolbag to the dormitory.

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

"Xu Qingzhou?"

"Yes."

There were four people left in the classroom.

"Xu Xu Shidi, awesome," Wan Hao expressed his admiration for Xu Qingzhou simply and clearly.

Xu Qingzhou smiled modestly.

The two stumbling blocks were gone, and the next step was subsequent verification.

But it wouldn't start until the afternoon. Professor Zhong and the others went to eat. Xu Qingzhou had nothing to do, so he simply took out two sets of conjecture materials from his bag and spent noon reading them.
