Zhou Yu walked into the quantum computer laboratory and knew that the quantum computer prototype had been developed.

The quantum computer prototype can realize various functions expected by quantum computers, and the quantum computer project can be declared successful.

The quantum computer they developed was only 30 qubits.

This is just a barely available quantum computer. In the future, the quantum computer laboratory will develop quantum computers with hundreds of quantum bits.

Zhou Yu came to a dust-free laboratory covering an area of ​​500 square meters, with a huge equipment lying across the center of the laboratory.

The center is a huge sphere with a diameter of two meters. It is the most conspicuous. Many researchers also look at the parameters around it, and it is the most core equipment of quantum computers.

On the upper left side of the laboratory is a hovering pipe, which looks like a large mosquito coil placed on the ground.

On the right side of the laboratory is a row of cabinets with flashing lights, which occupy almost a quarter of the laboratory.

Zhou Yu walked directly to the edge of the big ball and a young man about the same age as him.

The young man was wearing a white anti-static coat in the laboratory, staring at the data displayed by the big ball.

This person is Zhang Wei, director of the Quantum Computer Laboratory, and a favorite student of Academician Pan.

Because he accidentally got AIDS because of his friends, he voluntarily resigned from a laboratory under the Chinese Academy of Sciences. When he came to the Xinghuo Science and Technology Research Center for treatment, he became familiar with scientists.

Zhang Wei was recruited by Academician Tian Kai to the Quantum Computer Laboratory, and soon became the leader of the Quantum Computer Laboratory with his ability.

Academician Tian Kai walked over and said, "Zhang Wei, please introduce quantum computers to me and Mr. Zhou."

"Hello, Mr. Zhou, and hello, Director Tian."

Zhang Wei pointed to the huge sphere beside him and introduced: "This device is the most core quantum coherent sphere of quantum computers."

The most essential features of quantum computing are quantum superposition and quantum coherence.

The transformation implemented by a quantum computer on each superimposed component is equivalent to a classical calculation, and all these classical calculations are completed at the same time. This is the quantum parallel operation of a quantum computer.

Whether it is quantum parallel computing or quantum simulation computing, quantum coherence is essentially used.

Zhang Wei proudly said: "As we all know, quantum computers can realize their functions, they rely on quantum coherence.

However, quantum coherence is difficult to maintain in actual systems.

In quantum computers, qubits are not an isolated system. They will interact with the external environment, resulting in attenuation of quantum coherence, i.e. decoherence.

If we want quantum computing to become a reality, one of the core issues is to overcome coherence removal.

This device is designed to overcome quantum coherence removal of quantum computers and enable quantum bits to implement quantum parallel computing and quantum simulation computing."

Zhou Yu smiled, and he finally discovered the knowledge points he knew.

"I know this, quantum encoding is the most effective way to overcome coherence discovered so far.

Several main quantum encoding schemes include quantum error correction code, quantum error avoidance code and quantum error prevention code.

Which coding scheme do you use? Is this the coding scheme you have studied in collaboration with Director Wei Tianpeng and others?”

Zhou Yu was a little surprised. They kept it so confidential. Zhou Yu only focused on key progress in the general project.

However, it involves cooperation between multiple laboratories. As the director of the Spark Science and Technology Committee, he is responsible for coordinating various laboratories. He basically knows what cooperation he has.

Zhang Wei was stunned for a moment and explained with a smile: "Mr. Zhou, we have not used quantum encoding to solve the problem of decoding.

This solution is a completely trap, which is an important reason why a real quantum computer has not been developed yet.

The quantum encoding scheme only uses encoding, that is, software schemes, to artificially compensate for the missing part of qubit information.

Quantum mechanics explains that quantum is in Schrödinger's cat state at all and cannot be observed by people at all. Subjectively supplemented by encoding, which completely destroys the quantum state.

The results calculated by this quantum computer must be incomplete results, and the most important capabilities of quantum computers cannot be perfectly utilized."

Academician Tian Kai reminded: "Zhang Wei, what are you explaining! It directly explains how your related ball works.

The basic operation of this quantum computer prototype is what we want to know.”

Zhang Wei said in a little puzzled manner: "I was a little nervous when I was under the inspection of President Zhou for the first time.

This is also a habit I brought from the Chinese Academy of Sciences, and the leaders there like us to explain this.

The more profound the statement, the more unclear it is, so they feel that this project has a promising future and will increase investment in this project.”

Zhang Wei said this immediately eased the slightly awkward atmosphere at the scene.

He also briefly explained the principle of quantum coherent sphere operation. It is actually very simple. The two most obvious forces in the microscopic field are strong interaction forces and weak interaction forces.

Quantum decoherence is because the external system affects the qubits, so it uses strong interaction forces and weak interaction forces to form a force balance system.

Quantum bits at the equilibrium point are offset by external influences, which slightly equals no impact.

This method is the most universal and efficient method at this stage.

It cannot completely offset the external influence on qubits, but it can minimize this influence and allow qubits to maximize coherence.

Zhang Wei said with some gratitude: "I also want to thank Zhao Zhao, a scientist in the Neutral Bird Laboratory.

He used heavy particles to capture neutrinos with weak interaction forces, which gave me inspiration. I could only develop quantum coherent spheres.”

Zhou Yu clapped his hands and said excitedly: "It's easy for me to understand that you say this. Isn't it the Lagrangian point equivalent to the celestial body, and the object at this point is in a state of gravitational equilibrium."

Zhang Wei showed a look of surprise on his face. The gap between celestial mechanics and quantum mechanics is too big. These are two things that are completely unrelated.

"The principles vary greatly, but the effects are similar, which is to try to keep the qubits balanced with the external system."

When Zhou Yu saw Zhang Wei's helpless face, he knew that he had said the wrong thing just now.

He was about to continue to understand the situation of quantum computer prototypes, but suddenly he thought that the quantum coherent sphere was the core equipment of quantum computers.

As long as you obtain this technology, you can determine whether this development path of quantum computers is feasible.

"Supervisor Zhang Wei, show me the principles of quantum coherent sphere technology, and I will understand how you can implement this technology."

Zhang Wei used Star Spirit glasses to send Zhou Yu the technical principles of quantum coherent spheres. The expression on his face was very strange, and there was no belief in curiosity.

He believes that Zhou Yu cannot understand the technical principles of quantum coherent spheres at all.

Zhou Yu carefully read the technical principles of quantum coherent spheres. He understood a little bit, and golden raindrops kept falling in the space of the science and technology tree in his mind.

The technology tree digests this knowledge and feeds the knowledge to Zhou Yu, so he can understand the next knowledge.

Through this positive feedback method, Zhou Yu quickly digested the knowledge of quantum coherent spheres.

The science and technology tree in my mind swayed, and some quantum computer technology grew in the computer technology area.

Zhou Yu instantly learned about more advanced quantum coherent sphere technology.

He also knew that this path to development of quantum computers was completely correct.

Zhou Yu stared at Zhang Wei, with a smile on his face, and the next time he showed off his skills.

When Academician Tian Kai saw Zhou Yu's expression, he looked at Zhang Wei with caring eyes, and never be hit later.

At the same time, many fragments emerged in his mind, which were all about discussing technology with Zhou Yu before, and he thought Zhou Yu didn't understand this technology.

Unexpectedly, Zhou Yu interpreted this technology through an alternative perspective and helped himself solve the technical difficulties.
