Chapter 410 Quantum Entanglement

"Master." Ding Wenchao ran to Zhuang Weiran's side and whispered, "You seem to be late today?"

Today was originally a general meeting, and Wei Yaoyang, who always arrived early, was late for more than 20 minutes.They were all a little dumbfounded. It was the first time that the vice-team was late after getting married for so long.what happened?Is the sister-in-law pestering the deputy team to keep him from leaving the house?It seems not.

"Ahem, I moved recently." Wei Yaoyang glanced at Ding Wenchao, so he came late.

"Xiao Ding can do whatever he needs to do."

"Yes, master." Ding Wenchao didn't think too much, and started to do things after leaving.

Chen Jin leaned his head and looked at Wei Yaoyang outside the door, "Deputy team, have you been busy recently?"

"It's okay." Wei Yaoyang glared at Chen Jin, "If you don't cause trouble for me, nothing will happen to me."

"Ahem, deputy team, what you said, it seems that I have caused you something."

"Isn't it?" Wei Yaoyang glared at Chen Jin, "If you have nothing to do, hurry up and find something to do, or do you need me to find something for you to do?"

"No... no need!"

Chen Jin hurriedly gave up and left, while Wei Yaoyang buried his head and continued to deal with official duties.

Quantum computer, simply put, is a machine that can realize quantum computing, a system that can realize mathematical and logical operations, process and store information through the laws of quantum mechanics.It uses the quantum state as the memory unit and information storage form, and quantum communication and quantum computing based on the evolution of quantum dynamics as the basis for information transmission and processing. In quantum computers, the size of various components of its hardware reaches the order of atoms or molecules.A quantum computer is a physical system that can store and process information represented by qubits1.

The so-called quantum computer needs to use mathematics and logic calculations and follow the principles of quantum mechanics.Zhuang Weiran looked at the information in his hand thoughtfully, the cold wind howled outside.Now is the coldest December, even if there is no snow outside, it is definitely very cold.The heating was turned on in the room, and the black clouds blocked all the light. Under the light, Zhuang Weiran was thinking.

The door was pushed open, and Colonel Wu walked into the room, knocked on the door and said, "Professor Zhuang, it's almost ten o'clock now? Are you going to work overtime on your first day here?"

"It doesn't count as overtime." Looking at the information in his hand, he didn't raise his head, "Colonel Wu, I just want to know how far you have gotten. Now it seems... It seems that there is still a gap from what I imagined."

Colonel Wu smiled awkwardly, "Sorry, Professor Zhuang, we seem to have disappointed you."

"It's not disappointment." Zhuang Weiran shook his head, "Don't worry, take your time, there are still two years..."

After sorting out the information, "It shouldn't be long since I first started doing this, right? I checked the progress, and it probably started a month ago."

"The first research group should have started two months ago, and the general research group started a month ago."

"En." Zhuang Weiran nodded slightly. Colonel Wu looked at Zhuang Weiran and said with a trace of doubt, "Professor Zhuang, do you think there is any problem?"

"No."

Zhuang Weiran shook his head, "It's not a problem, I have to think about it. I have really thought about quantum computers, but you know, I just think about it casually. I haven't done anything specifically Some...experiments or specialized research in this area will take a while."

"There is no problem with this at all." Colonel Wu said seriously, "However, there are only two years..." He seemed to hesitate, "If it really doesn't work, the time can be extended later."

"No need." Standing up, Zhuang Weiran looked at Colonel Wu, without much expression on his face, and said with a businesslike face, "I personally think that two years should be more than enough. I personally don't like to study a subject too much. For a long time, unless... the challenge of the subject keeps me motivated."

Colonel Wu did not speak, but looked at Zhuang Weiran.

This sentence is a bit too loud, and he can also understand that it is very normal for a genius like Zhuang Weiran to be a little arrogant.If he didn't have arrogance, he wouldn't be Zhuang Weiran.

But he still feels a little unrealistic to solve the problem of quantum computers so quickly.Not knowing what Zhuang Weiran would do, Colonel Wu mused and did not speak.

"Colonel Wu, I'm going back." Zhuang Weiran walked to Colonel Wu's side, "Or, does Colonel Wu have anything else to tell me?"

"No." Colonel Wu shook his head, Zhuang Weiran was the chief person in charge, and besides, he knew nothing about scientific research.It is the most taboo for an outsider to give advice to an insider. He does not have such power, nor does he have such a big face to tell Zhuang Weiran what to do.

"Then I'll take my leave first." After Zhuang Weiran finished speaking, she left directly.

Colonel Wu looked at the back of Zhuang Weiran leaving, thinking deeply.

Go home and turn on the computer.He is still thinking about quantum computers, which need to follow the rules of quantum mechanics.In this area, Zhuang Weiran can say without hesitation that he is the best person in this area.

Probably in the entire Huaguo, there are not ten people who are better at quantum mechanics than him.

As we all know, he is not only a mathematician, but also a theoretical physicist.When Wei Yaoyang returned home, he saw Zhuang Weiran rubbing his eyebrows and thinking about something, walked to his side and said softly, "Honey, what's wrong?"

"It's nothing." Zhuang Weiran closed his eyes, "At this stage, this subject is indeed a bit difficult...I think about it, there should be a way to solve it."

"Hmm... what is the solution?"

Wei Yaoyang sat beside him without saying a word.

"Wait!" Zhuang Weiran suddenly opened his eyes, with a smile on his lips, "I remembered, if it is possible...it is indeed possible to make a quantum computer."

"Ah?" Wei Yaoyang looked at Zhuang Weiran with a puzzled face, not knowing what Zhuang Weiran was thinking of, Zhuang Weiran seemed strange to him.Anyway, he couldn't describe that feeling, his wife gave him a very strange feeling.He doesn't know what his wife is researching, he only knows that it seems to be a very powerful and core technology.

Although he didn't know what Zhuang Weiran wanted to study, he knew very well that Zhuang Weiran must have thought of something to be so happy now.That cheerful look made him very happy too.

The research work was carried out in an orderly manner. After the meeting, Zhuang Weiran devoted himself to the research.Wei Yaoyang naturally commutes to and from get off work every day. He originally planned to travel to Qiong Province, but Zhuang Weiran has to do research. It is not interesting for him to go to Qiong Province alone. It is better to work overtime in the unit and get some overtime pay.Even during the Chinese New Year, Wei Yaoyang felt that Zhuang Weiran was much busier than in previous years.Probably because Zhuang Weiran stayed in the research institute every day, when he was not on duty, he was bored at home and went out for a walk, and found it quite boring.I can only chat with my colleagues at home and watch TV alone at home.

Probably because they are in the military, they cannot come and go here casually.Zhuang Weiran definitely can't drop by, he is too busy and needs him to do everything.Every day as soon as he sits down in the research institute, many things come to his door, not to mention visiting, he doesn't have the energy to take care of the students.Pierce and Qian Mingzhang have already handed in their Ph.D. graduation projects. As a professor, he should attend their academic report meeting.It's a pity that he can't spare time to attend their academic report meeting.

Qian Mingzhang needs to return to the University of Science and Technology of China to give an academic report, while Pierce will give an academic report at Longcheng University.He probably won't be able to go to the academic report meeting of the two of them.Qian Mingzhang was in March and Pierce was in May.

If it is necessary to complete the quantum computer in two years, I am afraid that Liang Ming will not even be able to participate in the thesis defense.

Rubbing between his brows, Zhuang Weiran was thinking about something.In fact, the most difficult point for them is quantum entanglement. If this problem can be solved, then there will be nothing ahead of them.Unfortunately, quantum entanglement is simply too difficult.Zhuang Weiran has been thinking about this since a month ago, but unfortunately, he still hasn't come up with a solution.

Wei Yaoyang wanted to go out with Zhuang Weiran, but unfortunately Zhuang Weiran didn't have any free time at all.

Sitting in the office, Zhuang Weiran frowned and was thinking hard about the problem.Looking at the researcher next to him, Zhuang Weiran frowned.He wanted to say something, but in the end he didn't say anything.

"Professor Zhuang, do you have anything to do?"

"It's okay." Zhuang Weiran shook his head, "I think we still need to discuss the issue of quantum entanglement."

"The problem is..." After a pause, the researcher looked at Zhuang Weiran and said, "Professor Zhuang, the quantum entanglement we are doing now does not seem to be useful."

Zhuang Weiran turned around and looked at the person next to him and said, "Yes, the quantum entanglement we are doing now is useless. So we need to continue to do quantum entanglement."

"In quantum mechanics, the entangled state of multiple systems is the most common form of the quantum state of the entire system, and the non-entangled quantum state (or pure state) can be considered as a special entangled state with zero entanglement. The most widely used , The most studied entangled state is the entangled state with the largest entanglement degree, which is called the maximum entangled state.

According to the theory of quantum mechanics, there is no entanglement in a system of individual particles.For the convenience of discussion, the quantum state of a single particle system with two states, that is, the qubit, is shown. 2"

Zhuang Weiran pondered and said, "We still need to discuss this part of the problem."

"About this part, we are very clear." The researcher said with a wry smile, "Ichalewicz's standard test function has d! local minima when 0≤xi≤10, (i=1,...,d) There is a global minimum = -2; there is a global minimum = -1801 at d=5. 46877"

"But we still haven't been able to calculate the result of quantum entanglement."

"So I want to think about how to make a result that is suitable for a quantum computer." Zhuang Weiran looked at the researcher next to him, "Continue to calculate."

"Okay." The researcher sighed, buried his head and continued to make calculations.

Professor Zhuang also participated in the calculation of quantum entanglement, but it still seemed to have no effect.
