From a university student to a chief academician

Chapter 272 Invitation to start the lecture, quantum decoherence
Jinling, Institute of Cosmos, Ye Fei's office!

Ye Fei is sitting on an office chair at the moment, looking at the computer screen, browsing Stack Exchange, and checking the evaluation of his recent research by scholars around the world.

Because of the multi-universe interpretation proposed by Ye Fei, scholars all over the world are discussing it.

In the Stack Exchange quantum mechanics section, five out of ten posts talk about multiverse interpretation.

After a long time, Ye Fei, who was close to the computer screen, leaned back and said with a chuckle, "It seems that the multiverse interpretation I proposed is very popular!"

"As the Israeli physicist Sefivor House said, I just assume that parallel universes exist."

"But it doesn't mean I admit that parallel universes exist."

"There's an essential difference here."

"It's just that some people insist that I admit the existence of parallel universes, and here are the scholars from Beili Country."

"As for saying that I am assuming the existence of parallel universes, I do not admit the existence of parallel universes. This is represented by some scholars in Europe and most scholars in Asia."

Whether Ye Fei's interpretation of the multiverse admits the existence of parallel universes does not make any difference academically, but there are differences from other standpoints.

As mentioned above, scholars like Ye Fei should not say anything nonsense, otherwise it will arouse world public opinion.

If Ye Fei admits the existence of parallel universes, it will have a certain impact on his personal reputation.

Of course, unless Ye Fei proves the existence of parallel universes by scientific means.

But at that time, it was not a question of Ye Feicheng's acknowledgment of the existence of parallel universes, but a civil war concerning the survival of the entire earth.

At this time, there was a knock on the door, and Ye Fei said, "Please come in!"

The assistant opened the door and came in, walked up to Ye Fei, and said, "Dean, Director Yang of CCTV called just now, and I hope to talk to you."

Ye Fei asked with some doubts: "Why didn't he call me?"

Director Yang is the director of CCTV, and Ye Fei has known him for many years.

After all, many of Ye Fei's interviews were conducted by CCTV.

Master Yang has Ye Fei's phone number, but the two rarely talk on the phone. Only when Ye Fei is about to be interviewed, Master Yang will call Ye Fei himself.

The assistant said, "He said your phone was turned off."

"It's turned off?" Ye Fei took out the phone from his pocket in confusion, and then saw the phone's black screen, he pressed the power button, and the low battery sign was displayed.

Ye Fei smiled wryly, "It turns out that the phone is out of battery and turned off."

After finishing speaking, he looked up at the assistant and said, "Okay, I see, you go out!"

"Okay, Dean!"

After speaking, the assistant went out.

After the assistant left, Ye Fei found the charger from the drawer of the desk, plugged the charger into the socket on the side, charged the phone, and turned it on. He saw that Director Yang had called him five or six missed calls.

Immediately, Ye Fei called Master Yang and said with a smile, "Tailor Yang, I'm sorry, my cell phone is out of battery and turned off, and I didn't notice it myself."

"I'm so sorry!"

Master Yang smiled and said, "It's okay, you're busy, it's normal to forget to charge your phone."

Ye Fei said: "Master Yang, I wonder what you want from me?"

Tai Yang said: "Academician Ye, I would like to invite you to give a lecture on this program. Do you think it is feasible?"

Master Yang just had the attitude of giving it a try, he wasn't sure if Ye Fei would agree.

Because in the past, Ye Fei once turned down to participate in the opening lecture program.

But this time he invited Ye Fei again because Director Hao, who hosted the opening talk show, begged him repeatedly.

Coupled with Ye Fei's current popularity, if Ye Fei came to participate in the opening talk, the ratings of the opening talk program would definitely explode.

Therefore, he extended an invitation to Ye Fei again.

Yang Taichang said: "Academician Ye, the lecture is about to start, but there are many famous scholars in China to participate, such as Mr. Qiu Chengtong, as the leader of the younger generation in China, you are the only winner of the Fields Medal in the Xia Kingdom and the second in the world. The person who proved the eight conjectures of mathematics."

"You should come to the opening lecture, which has a very stimulating effect on the youth of our country."

Before calling Ye Fei, Director Yang had already prepared a draft.

People like Ye Fei are not short of money, fame, status and rights, so they can only talk about Ye Fei from the heart of patriotism.

Ye Fei thought for a while and said, "Okay, when will you go to Kyoto to record a show?"

When Master Yang heard this, he was overjoyed and said with a smile, "How do you see next week?"

"Okay, what time is next week?"

Tai Yang said: "The time is arbitrary, it is up to you."

Ye Fei thought for a while and said, "Then next Friday at [-] o'clock in the afternoon!"

Originally, Ye Fei wanted to talk about next Sunday, but considering that the TV station also had Saturdays and Sundays, he set the time for next Friday afternoon.

"Row!"

After hanging up the phone, Ye Fei didn't take the matter of going to CCTV to record the program to heart.

meeting room!
The team leaders of the Institute of Cosmos sit among them.

At this stage, the Institute of Cosmos mainly studies quantum science. There are many research fields of quantum science, so it is divided into many groups.

At the moment, they are chatting with each other.

After a while, Ye Fei opened the door and came in, taking the first seat.

When everyone saw Ye Fei coming in, they immediately shut up and stopped chatting.

Ye Fei glanced at the crowd and said, "After this period of research on Schrödinger's cat, we have overcome some difficulties."

"Next we are going to prepare to overcome quantum decoherence!"

Quantum decoherence belongs to the category of quantum coherence.

Quantum coherence is some important quantum properties of quantum computers.

When Ye Fei was researching quantum computers, he also studied part of quantum coherence, but the research was not complete.

After all, in order to develop a quantum computer as soon as possible, only the most helpful part of the quantum computer was studied.

Therefore, it is impossible for Ye Fei to study all parts of quantum coherence.

Quantum coherence says that in a high-energy accelerator, an electron and a positron, generated by energy, are both flying in opposite directions, and when no one is watching, both are in right- and left-spinning superposition state.

When observing, if the electron is observed to be in the state of spin to the right.

Then, the positron must be in the state of spin to the left.

This is because positrons and electrons come from nothing through energy, and must obey the law of conservation.

That is to say, the right-spinning state of the electron and the left-spinning state of the positron are related.

This is quantum coherence.

The so-called quantum decoherence means that the quantum coherence of an open quantum system will gradually lose over time due to quantum entanglement with the external environment. This effect is called quantum decoherence.

Quantum decoherence, in the study of quantum science, is an unsolvable problem that has always been troubled.

If this problem is solved, the performance of quantum computers can be greatly improved.

In Schrödinger's cat research, the cat may be dead or alive, but it is also possible that the cat is both dead and alive.

The third possibility does not exist in reality.

But in quantum theory, it exists.

The cat is both dead and alive, which is a quantum superposition state.

However, the quantum superposition state only exists in the microcosm, not the macrocosm.

The question of why the quantum superposition state only exists in the microcosm but not in the macrocosm has always puzzled countless scientists.

Many scientists have found quantum decoherence to explain this phenomenon, but this mystery has not been solved yet.

Ye Feidao: "Using quantum decoherence to explain the quantum superposition state of cats in the microcosm and macrocosm can help us take Schrödinger's cat a step further."

Everyone nodded slightly. This problem has long existed in the scientific community.

Many people are using quantum decoherence to study Schrödinger's cat.

Ye Feidao: "Let me just say that to study Schrödinger's cat with quantum decoherence, we must start from the field of wave functions of particles."

"It should be a feasible direction to study the entanglement between particles."

When everyone heard this, they all took out their notebooks and recorded it.

You must bring your notebook to the meeting, and Ye Fei will talk about some constructive research directions at the meeting.

Every time Ye Fei said the direction was basically correct, and the number of mistakes was relatively small.

Even if you make a mistake later, you can quickly find a solution.

After the meeting, they began to dive into the research.

Ye Fei didn't stay idle either, and devoted himself to the research together.

When Ye Fei and others were engaged in research, the official website of the program released the news that the guest Ye Fei will be the speaker next time.

When they heard the news, there was an uproar on the Internet, and many netizens were overjoyed, especially young people.

Many young people are eagerly looking forward to being lucky enough to be the audience of the lecture.

However, the audience is invited by the program group after the lecture, and it is difficult to become one of the audience.

For this reason, many people even called CCTV, hoping to invite them to be the audience of Ye Fei's talk.

CCTV!
"Director!" A middle-aged man walked into Director Hao's office.

The deputy director is in charge of the talk show, and his surname is Hao.

And the middle-aged man is the director who started the talk.

The director said excitedly: "You don't know, since we announced that Ye Fei will be the guest of the next episode, there has been a lot of discussion on the Internet, and many people want to be the audience of Ye Fei's lecture in that episode."

"It's also on the hot search for this!"

Director Hao laughed and said, "With Ye Fei's current popularity, this phenomenon is normal. I believe the ratings will be very high by then."

The director nodded and said, "Yes."

Then, he asked again: "Director, should the advertiser's price for Ye Fei's program be raised?"

"This is for sure." Director Hao said: "Let the people from the Ministry of Commerce discuss this aspect."

"Since Ye Fei is so hot right now, let's take advantage of the situation and increase publicity."

"The more heated this matter is, the better."

The director said: "That's for sure, I will tell the people in the propaganda department later."

"Director, I think we should change the content of the show."

"Huh?" Director Hao looked at the director and asked in confusion, "How do you want to change it?"

After pondering for a while, the director said: "I think that apart from Ye Fei's personal speech, we should increase the interaction between Ye Fei and the audience."

"Since Ye Fei is a mathematician, let's do some math-related interactions."

"For example, let the audience ask some math questions and ask Ye Fei to answer them."

"Ye Fei asked some math questions for the audience to answer."

"Of course, math problems are definitely no problem for Ye Fei, we need to remind Ye Fei not to come up with too difficult math problems."

"Also, for the audience, we should invite undergraduates, masters and doctoral students majoring in mathematics from prestigious universities."

"In this way, they won't be unable to answer the math problems Ye Fei raised."

Director Hao nodded after thinking for a while and said, "That sounds good, you can make a plan for me later."

"But don't embarrass Ye Fei during the show. Even if the show is not good, you can't embarrass Ye Fei."

"After all, Ye Fei is different from the guests we invited in the past."

"Ye Fei's reputation and influence are very high in Xia Kingdom."

The director patted his chest to reassure, and said: "Director, you can rest assured about this, I have a measure."

Director Hao nodded slightly and said, "Okay, then you can do it!"

"Okay, Director." The director said.

After speaking, he turned to leave.

A few days later, the lecture invited students from the mathematics department of the top ten universities in the country to participate in the lecture.

Mizuki University, male dormitory!
Suddenly, cheers came from a dormitory: "I have been selected by the lecturer, and I can go to see Ye Fei's lecture on the spot."

I saw a boy in the dormitory jumping and shouting excitedly.

The other three roommates looked at him enviously.

After a while, the boy stopped dancing. He looked at the three roommates with a hearty laugh, and said, "Brothers, don't be discouraged. When I go, give me your photos. I will carry them with you. Black and white." Yes, this proves that I have gone, and you have also gone."

"Get lost..." The three threw books, or shoes, or pillows at him.

The boy dodged left and right to avoid their attacks, then ran out of the dormitory with his head in his arms, poked his head at the door frame and looked into the dormitory, saying: "If you are envious, then envy, don't throw things at me!"

The three roommates looked at each other and said, "Fuck him!"

After finishing speaking, the three of them rushed towards the boy. Seeing this, the boy yelled and ran out.

This situation is happening in Xia Guo's top ten universities.

Let's start the lecture. Three people will be selected from each of these schools, for a total of 30 people.

There is one undergraduate, one master and one doctoral student majoring in mathematics, and the grades of these people are among the top in the school.

Jinling, Institute of Cosmos, laboratory!

Ye Fei wrote down a set of formulas on the whiteboard.

【|Ψ>=｜粒子一的第1个状态>.|粒子二的第1个状态>|环境的第1个状态>+|粒子一的第2个状态>.|粒子二的第2个状态>|环境的第2个状态>+】

After writing the formula, Ye Fei put down the pen in his hand, looked at the researchers beside him, pointed to the content on the whiteboard, and said, "This is the structure of the wave function we studied recently."

"That's superposition!"

"It can be seen from this formula that each state is obtained by multiplying the respective states of all particles in the system and the state of the environment, and then the entire wave function is the superposition of all possible states..."

Friday!

Ye Fei was flying to Kyoto. When he got out of the airport, a middle-aged man and a young man came up.

The middle-aged man smiled and said, "Academician Ye, I am the deputy director of CCTV. My surname is Hao. This is my work permit."

With that said, Director Hao took out his work permit from his pocket and showed it to Ye Fei.

Ye Fei glanced at it, smiled and stretched out his hand, and said, "Hello, Director Hao."

It doesn't matter if you don't have a work permit. People like Ye Fei are surrounded by invisible corners, and there are many people who protect him 24 hours a day.

Besides, this is the capital of Xia Kingdom, and the law and order here is the best in Xia Kingdom, not even a mosquito can fly in.

Starting from Ye Feiluo in Kyoto, all his itineraries are under monitoring.

If there is any change, the security of the entire capital will be dispatched.

"Hello, hello, Academician Ye!" Director Hao stretched out his hands and shook hands with Ye Fei very enthusiastically.

A person like Ye Fei has a high status in Xia Kingdom, and there are too many people who want to curry favor with him.

Director Hao naturally faced Ye Fei with enthusiasm.

Tai Hao said: "Academician Ye, let's go!"

"Yeah!" Ye Fei nodded slightly.

After speaking, the group walked to the parking lot, got in the car and left.

After Ye Fei left, a young man next to him belatedly said, "The one just now was Ye Fei!"

The female companion beside him looked at the car that was drifting away, and said in surprise: "It seems to be so!"

The young man slapped his face regretfully, and said, "Fuck... I forgot to ask for an autograph. Ye Fei's autograph is very commemorative."
