From a university student to a chief academician

Chapter 256 Schrödinger's Cat Quantum Coherent State

Jinling, Academy of Sciences, Qubit Lab!

There are more than a dozen people sitting in the research room, and everyone is intensively researching the qubit part.

This is just one of the research laboratories. In the Academy of Sciences, there are dozens of qubit research laboratories.

From time to time, people get together to discuss the research part.

Ye Fei was sitting by the window, also studying qubits.

It has been two days since he came back from the National Quantum Research Center.

He did not tell everyone about the research on the quantum computer in North Li Country.

Even if it is said, it will only increase everyone's psychological pressure.

So, it is better not to say.

Ye Fei looked at the calculation in front of him, and thought: "Particles are orderly and controllable, so the single-quantum particle, double-particle and three-particle systems in the quantum state can strongly affect other particles in this area."

The particle world is like the universe, and each particle is like a planet.

The particles that have been discovered now are equivalent to the stars that have been discovered in the universe.

Undiscovered particles are equivalent to undiscovered stars in the universe.

There are influences from planet to planet.

For example, the sun affects the earth, and the earth affects the moon.

And the same is true between particles.

Interactions between particles can also occur.

"Qubits exist in multiple states, 0, 1 and 2."

"They exist randomly in one of the states."

"But..." Ye Fei's eyes lit up, and he felt a little excited: "That's what I said before, since the particles are orderly and controllable."

"Then, the presence of the qubit in the state is not random."

"It's known and controllable."

"Now that the qubit is controllable in three states, it partially justifies a very well-known study in physics."

"Schrodinger's cat!"

"Schrödinger's cat is about keeping a cat in an airtight container with a small amount of radium and cyanide."

"There is a chance of the decay of radium. If the radium decays, it will trigger the mechanism to smash the bottle containing the cyanide, and the cat will die."

"If the radium does not decay, the cat will survive."

"According to the theory of quantum mechanics, since radioactive radium is in a superposition of decay and non-decay states, the cat should be in a superposition of dead and alive cats."

"This dead and alive cat is the so-called Schrödinger's cat."

"And from a qubit, a cat dead is 0 and a cat alive is 1."

"According to the principle that the particles are orderly and controllable, if you want the cat to die, it will die, if you want the cat to live, it will live, and even if you want the cat to resurrect from the dead, it can be done."

Although this sounds fantastic, in reality, it is impossible to bring a cat back from the dead.

But it's science, in the world of science, that brings cats back from the dead.

"Of course, this is only in concept."

"Bringing cats back from the dead is only part of Schrödinger's cat research."

"It is still far from being able to prove all the problems of this century."

Schrödinger's cat is a quantum research that has a great impact on many fields of quantum.

If Schrödinger's cat is proved, then humans can control the decay of particles, and then prove the existence of quantum superposition state.

In layman's terms, the role of the quantum superposition state can make two things that are far apart move instantly.

It's teleportation, not movement.

Instantaneous movement, there is no time for two things to move.

For example, at nine o'clock in the morning, when A moves to B, the time is still nine o'clock in the morning.

And the separation between A and B is the distance from the North Pole to the South Pole, or more.

If quantum superposition is mastered, humans can be used in many fields.

It is even possible that it is only an instant for a person to go from the North Pole to the South Pole.

Ye Feixin said: "Now I should prove part of Schrödinger's cat, which is more conducive to the research of quantum computers."

The corners of Ye Fei's mouth twitched slightly: "I can find that the particles are orderly and controllable, and the Beili country probably hasn't discovered it yet!"

"Then, the performance of the quantum computer they developed is definitely not as good as ours."

"Since developing a quantum computer, develop the best one."

"The quantum computer that we strive to develop will make it impossible for the North Li country to catch up for decades."

After thinking for a while, Ye Fei said, "Schrödinger's cat? I'm not very deep into this research. I should find some famous physicists in China to study it."

Half a month later!
The gate of the Academy of Sciences!

Ye Fei stood straight at the gate, as if waiting for someone.

A moment later, a minibus stopped at the gate, and then a group of people got off from it, led by a middle-aged man in a black tunic suit.

Ye Fei stepped forward with a smile, and stretched out his hand from a distance: "Academician Pan, welcome to the Academy of Sciences!"

Academician Pan shook hands with Ye Fei with a smile, and said, "Academician Ye, I have admired your name for a long time!"

Ye Fei smiled and said, "I've also admired you for a long time!"

Academician Pan, whose full name is Pan Jianlei, is the father of Xia Guoquan.

Mainly engaged in the research of quantum optics, quantum information and technical problems of quantum mechanics.

Vice President of Xiaguo University of Science and Technology, Academician of the Academy of Sciences and Academy of Engineering.

Ye Fei asked the Science and Technology Department for a group of quantum physicists half a month ago.

Therefore, the Science and Technology Department sent Fan Jianlei and some quantum physicists.

Academician Pan smiled and said, "Academician Ye, we still ask you to take care of us."

"Where!" Ye Fei smiled and said, "Let's help each other!"

Ye Fei looked at the rest of the physicists and said with a smile: "Everyone, please feel free to come to my place and treat this place as your own home."

"In the days to come, please help me a lot, thank you very much."

"Academician Ye, I'm bothering you."

Ye Fei said, "Let's go, I'll take you to dinner."

Ye Fei didn't take them to the hotel, but just had a meal in the cafeteria.

Everyone is not short of money and status, what delicacies have never been eaten!
In the afternoon, Ye Fei arranged for all of them in a room, which is where they will do research next.

Ye Fei stood in front of the blackboard and wrote down a bunch of formulas on it.

All the physicists sat on the stools below, curiously looking at what Ye Fei wrote.

After a while, Ye Fei put down his pen, turned to face the crowd and said, "Everyone, I went to the National Quantum Research Center some time ago and did a small experiment there."

Ye Fei pointed to the formula on the blackboard and said, "Through this formula, it was discovered with a particle accelerator that the particles are orderly and controllable."

In an instant, it was quiet below, and everyone looked at Ye Fei in astonishment.

After a while, Academician Pan said with a dry smile: "Academician Ye, are you right, the particles are orderly and controllable?"

Academician Pan has studied quantum science for decades, but he has never heard that particles are orderly and controllable.

Particle disorder is common sense in physics, and no one has refuted it.

As for the controllable particles, this is even more nonsense.

Ye Fei said: "I'm not wrong, the particles are orderly and controllable."

In an instant, everyone below shook their heads.

They still can't believe it's real.

Particle disorder is a common-sense problem, but now someone tells them that particles are ordered and even more controllable.

It was as if someone told them one day that water flows backwards, soil can be eaten, and people can fly into the sky.

Ye Fei looked at the crowd in disbelief. He knew that no one would believe it if he hadn't seen it with his own eyes.

Ye Fei said: "I know you don't believe it, but please believe me, it's true."

"It is impossible for me to deceive you in this matter, and I have no reason to deceive you."

Everyone thought about it, and it seemed so.

However, they still do not believe that particles are orderly and controllable.

However, intellectually speaking, it is impossible for Ye Fei to deceive them.

There is no benefit for Ye Fei to lie to them.

But reason tells them that particles are indeed disordered and uncontrollable.

Both ideas were right to them, but both ideas were opposite.

For a moment, they didn't know which idea to believe.

Academician Pan let out a breath, and said, "Academician Ye, we know that you can't lie to us, but the particles are orderly and controllable, how is this possible!"

"This is completely impossible!"

Ye Fei shook his head helplessly and said, "Okay, then I'll find someone to tell you!"

After speaking, Ye Fei took out his mobile phone and called Academician Yang of the National Quantum Research Center.

The call was quickly connected. After Ye Fei explained the situation, he added Academician Yang's WeChat and connected to the WeChat video.

Academician Yang stood beside the small particle accelerator and said, "I will verify what Academician Ye said now, and you will know after reading it."

Everyone nodded. Academician Yang and the others knew that they often used small particle accelerators when they were doing experiments, so they also knew Academician Yang.

Ten minutes later, the video shows the particle changes on the screen of the small particle accelerator.

Everyone's eyes widened in surprise, and they muttered to themselves: "This is actually true!"

Seeing everyone's surprised expressions, Ye Fei smiled slightly.

Ye Fei said: "Everyone, believe me now!"

Everyone looked at Ye Fei in a daze.

Academician Pan asked: "Academician Ye, how did you do it?"

Ye Fei pointed to the formulas on the blackboard and said, "These are the formulas."

Everyone gasped, it was really shocking.

Particle disorder is a common sense in the physics world, but Ye Fei broke this attempt today.

If the particles are ordered, it can indeed be controlled.

This can also explain why Ye Fei said that the particles are controllable.

Lights flashed in many people's eyes.

If the particles are orderly and controllable, then many studies and proofs in the physics world can be unraveled.

Everyone clenched their fists excitedly.

They didn't expect to encounter such a big surprise when they came here.

After a long time, after everyone calmed down, Ye Fei said: "As we all know, particles are orderly and controllable, which can help the quantum state..."

Ye Fei talked a lot, and finally said: "I seconded you here to ask you to help me prove part of the problem about Schrödinger's cat, and then help me complete the research on quantum computer theory."

Academician Pan nodded, and said in a deep voice, "If the particles are orderly and controllable, it will indeed be of great help to prove Schrödinger's cat."

The rest of the people also nodded.

Ye Feidao: "Let me explain next, how this mathematical formula makes understanding orderly and controllable."

Everyone nodded, very happy in their hearts.

They are all looking forward to the formula that can make the particles orderly and controllable.

If learned, it will also be of great help to many of their own research.

In the next few days, Ye Fei explained the formula to them.

After explaining, they proceeded to prove Schrödinger's cat.

Academician Pan said: "Academician Ye, I want to prove Schrödinger's cat and help quantum computers."

"Then, my suggestion is to start with quantum coherent states."

Quantum coherent state has been the focus of attention of physicists since the birth of quantum theory.

Academician Pan said: "The double-slit interference phenomenon is the most typical quantum interference phenomenon."

"In an interference experiment, if one particle connects through two adjacent slits on the partition..."

"..."

"The physics community hopes to explore the nature of decoherence by studying the change of quantum coherence in the process from microscopic objects to macroscopic objects."

"..."

"Tardigo worms are so tenacious that they can survive exposure to outer space for days."

"If it is placed in an ultra-high vacuum experimental environment, it can remain alive, thus meeting people's research requirements on the quantum superposition state of life."

"If this experiment is successful, a quantum superposition state very similar to Schrödinger's cat can be prepared."

"However, now Academician Ye can make the particles orderly and controllable."

"Then, there is no need for water bear experiments."

"It is completely possible to experimentally prepare a quantum superposition state that is very close to Schrödinger's cat through the double-slit interference phenomenon of the quantum coherent state."

"In this way, use Schrödinger's cat as a springboard."

"It can not only prove the qubit, but also prove the principle of state superposition and quantum entanglement."

"This could greatly speed up research on the theoretical part of quantum computers."

"And, most importantly, the quantum coherent state itself is very helpful for quantum computers."

"Without quantum coherent states, quantum computers cannot efficiently perform parallel operations."

"So, starting with a quantum coherent state has multiple benefits."

When Ye Fei heard this, his eyes lit up.

If it is true, as Academician Pan said, starting from the quantum coherent state will indeed have multiple benefits.

Ye Fei was excited: "Sure enough, it's right to find them. Quantum theory research is mostly physics research."

"They have studied quantum science for many years and accumulated a lot of experience, which is much better than my half-way monk."

Ye Fei smiled and said, "Academician Pan, your idea is really great, I never thought of it before."

Academician Pan smiled and said, "Hehe... I also came up with this idea based on your order and controllability of particles."

"Without your orderly and controllable particles, this idea cannot be realized."

The rest of the people also nodded.

The ordered and controllable particles discovered by Ye Fei are simply an earth-shattering event for quantum science.

Ye Fei didn't care, if it were someone else, they might have spread the word to the world and competed for the Nobel Prize in Physics.

"Luck, haha..." Ye Fei laughed and said, "I was also lucky to discover that the particles are orderly and controllable."

"Science has no luck!" Academician Pan said seriously: "All scientific research is a proof of strength."

"If you don't have strength, you can't discover what others can't discover."

"Okay!" Ye Fei didn't want to talk about this topic, and said: "Since we are sure to start from the quantum coherent state, let's start!"

The crowd nodded.

Next, Ye Fei's research began with the quantum coherent state.

The quantum coherent state is also called quantum coherence, or the correlation between states.

The quantum coherent state is the state in which the right and left spins of electrons are studied.

Since it has been found that the particles are ordered and controllable, it is of great help to the study of quantum coherent states.

This could greatly speed up the study of quantum coherent states.

As long as the quantum coherent state is successfully studied, the quantum superposition state will be established.

After the quantum superposition state is successfully established, the qubit, state superposition principle and quantum entanglement are proved.

Eight months later!

Ye Fei said with a smile: "Since the successful establishment of the quantum superposition state, it turns out that qubits, the principle of superposition state and quantum entanglement soon proved to be successful."

"Now only the most important puzzle of quantum computer theory remains."

"The principle of quantum parallelism!"

The principle of quantum parallelism is the most important and the most difficult part of the theory of quantum computers.

Ye Fei took a deep breath and said, "Time is faster than I imagined. If academician Pan hadn't proposed to start with the quantum coherent state, the speed wouldn't be so fast."

"Next, I will focus on the principle of quantum parallelism."

"Beili country developed a quantum computer in 2033. At the current speed, we can just run into them."

"At that time, we will see who is stronger!"

Ye Fei's eyes were full of fighting intent.

If it is before the development of quantum computers, Ye Fei has no confidence.

But now, Ye Fei is full of confidence.

"The quantum computer developed by Beili Country is definitely not as good as mine."

"After all, I discovered the law and controllability of particles."

"This is very helpful for the research of quantum computers."

"To put it bluntly, a quantum computer is a demonstration of quantum research."

"Theory is more important than application."

"As long as the theory is good, the developed quantum computer will be even better."

"I don't believe that North America's quantum computer theory can do better than us."

"Your 5G, Web3.0 and Li-Fi can't beat us, and quantum computers won't beat us."

"In the field of quantum computers, you can't kill us."

"Then, in the next hundred years, science will favor our Xia Kingdom."

Quantum computers, 5G, Web3.0, and other technologies are the basis for building the Metaverse.

The metaverse is a technology that completely changes the living habits of human beings, and it is even greater than the appearance of the steam engine.
