European Union headquarters, Brissel.

At this time, in a closed conference room, two men and one woman, three people sitting on a round table in a triangle.

Once again, outsiders will definitely recognize them.

The newly appointed British Prime Minister Paulis Johnson; French President Macaron; the German Chancellor who took over the German baton from the German "Iron Lady", and Anne Gretel Lenkabauer, known as the "Little Merkar".

This time I came to Brussels to participate in an EU meeting.

As too many things happened before, they also decided to meet today to discuss the future direction and countermeasures of Europe.

None of the three of them looked very good.

Because some time ago, they felt betrayal again.

The three countries on the island of the United States and Russia, while succeeding in controlled nuclear fusion technology, launched their controlled nuclear fusion research agreements at almost the same time, putting them aside.

Today, the three countries of the United States and Russia have made progress in controlled nuclear fusion technology, but Europe’s own controlled nuclear fusion technology has not broken through.

If this status quo continues to be maintained, in the near future, they will be surpassed and abandoned outside the door of a powerful country.

This is not what they want to see.

"That incident, once again proved that they are unreliable, what are they going to do next?" Macaron asked.

Both Johnson and Lenkabauer calmed down, not daring to speak easily.

After thinking about it for a while, there was finally some movement.

"In this special period, Europe must unite." Lenkabauer crossed his fingers and looked calm: "The wind of historical change is very important. Compared with the three countries of China, the United States and Russia, we must unite."

"So?"

Johnson looked at him seriously and asked her to continue.

"You should all have received some news about the reasons for their breakthroughs in controlled nuclear fusion technology."

Macaron and Johnson looked at each other and nodded slightly.

Things started to happen. Their intelligence department informed them of possible guesses. Now that the United States has announced artificial intelligence, they have confirmed the news.Moreover, the dispute between Russia Island and U.S. Island was also very strange, and they received a lot of news.

"Then what do you mean?" The two looked at Lenkabauer at the same time.

"Concentrate the artificial intelligence research team to research artificial intelligence and develop advanced artificial intelligence as soon as possible. We do not have a strong enough technical team and funds on either side of us. If we don’t work together, we can’t do anything. The change has already begun and we will never Prepare, we must withdraw from the center of the world stage."

With Lenkabauer's words, Macaroon and Johnson nodded gently.

This woman, who can take the big stick from the iron lady and take charge of the leader in Europe, is definitely not inferior to them.

"What do you suggest?"

"Concentrate the funds and technical talents of various European countries, concentrate the talents and technologies of various countries, and regroup the research teams. As long as we gather the top talents from each country, we will have the top team, and all technologies will be successfully shared." Bauer said.

The artificial intelligence research institute originally established by European cooperation, all of them have reservations. Now they are betrayed in the research direction of controlled nuclear fusion technology. They are indeed a little passive.

"If you agree, you can announce this news at the summit. Now China, the United States, Russia, and the island countries are all trying to snatch technical talents. If we don’t unite, we will be abandoned by the times. Don’t expect the United States to help us. The withdrawal of nuclear fusion technology is a reality."

Lenkabauer stopped.

She finished what she said, and the two of them chose.

In this era of technological explosion, they have no choice, otherwise they will retreat to the second-rate in the world.

"I agree." Macaron raised his hand and said.

Both looked at Johnson, and now only Britain was left.

After leaving the European Union, they are now in an embarrassing situation, but they are still the top three countries in Europe and one of the top five gangsters. They have been played so many times. If they still follow the United States, they can only be isolated.

"I agree."

Johnson also raised his hand.

...

"Landing..."

"100 metres……"

"50 meters……"

"10 meters……"

"Successful landing!"

On the far side of the moon, the edge of Zhihai once again welcomed guests, this time it was a behemoth Tianmai.

Chen Mo named this molten cave area: ant cave area.

Construction machines and helium-3 extraction machines have been launched continuously for several months. Today's ant hole area is a bit lively. The machines can work normally whether it is moonlight or moonlight.

It is the hour of the moon and day, and more than a dozen helium-3 extraction machines can be seen working, as well as a helium-3 extraction machine, which will collect the helium-3 and store it in a storage tank not far from the molten tunnel.

The Heavenly Girl could not hear any sound here, it was deathly quiet.

"Please note that the transport compartment is open."

The artificial intelligence of the Tiannv opened the door of the transport cabin, the robot in the transport cabin opened the seat belt of the fixed equipment, various machinery and equipment started, slowly left the transport cabin and entered the moon surface.

Except for the five helium-3 extraction robots, all the other robots go into the molten tunnel.

This time, there are a lot of them, and the volume of the machine is a bit larger than the one transported by the Goddess. There is also a toolbox containing several robot drill bits for the robot to replace.

A transport robot, carrying the helium-3 collection cabin, arrived at the predetermined position next to the lava tunnel and put it down, then took the already packed collection cabin back to the Tiannv.

The one-ton collection cabin is equipped with a refrigeration system, and there are 100 kilograms of helium-3 inside, which was collected by a helium-3 extraction robot and returned to the earth to be used as fuel for controlled nuclear fusion.

"Earth, this is the Celestial Woman, all missions are completed, request to return."

After all the robots have been put in, the collection cabin of helium-3 has been recovered, and after several robots have loaded some moon rock and lunar soil, the artificial intelligence of the Celestial Girl sends a request signal.

"Allowed to return."

In the laboratory in Building 1, Mo Nu received the signal and passed the instructions.

"Brother Mo, the Tiannv has returned."

"Ok."

Chen Mo, who was in front of the experimental platform, responded and looked carefully at the design drawing of the quantum chip in front of him.

This is the design drawing of the quantum chip made by Mo Nu based on his ideas.

The importance of quantum chips in manufacturing quantum computers is self-evident.

Quantum chips need to integrate quantum circuits into the substrate to carry quantum information processing.There are many ways to quantum chips, including superconducting systems, micro-nano photonics systems, atomic systems, ion systems and semiconductor quantum dot systems.

Chen Mo's research direction is superconducting systems.

He currently has room temperature superconducting materials, and the technology of superconducting quantum chip system is relatively easy to implement.

In terms of quantum chip research, Chen Mo has several technical solutions obtained in the Science and Technology Library, combined with some theories in reality, and chooses the best, hoping to develop more efficient quantum chips.

The difficulty of current research is to extend the decoherence time of qubits.

Quantum coherence refers to the special connection between quanta, which can be used to deduce other quantum states from one or more quantum states.

If a string of quanta is coherent with each other, the string of qubits can be regarded as a'community of destiny'. Processing one of the bits will affect the operating state of the other bits. The efficient operation of quantum computers is based on this characteristic of quantum.

Decoherence is the phenomenon of wave function collapse, one of the basic mathematical characteristics of quantum mechanics.

The simple explanation is that there is a continuous probability range of 0 to 1 states, and at the moment of'observation', it suddenly changes to a certain function point of 0 or 1.

A visual explanation is that in Schrödinger’s cat experiment, when Schrödinger did not open the box to'observe' the cat, the cat only lived in the box with a certain probability, in a superposition state of neither life nor death, that is, life and death. When the box was opened for "observation", the cat was originally uncertain about the existence of life and death. At the moment of "observation", the cat suddenly changed into reality, life or death, that is, 0 or 1.

The computing time of a quantum computer is affected by quantum decoherence.

The coherence between qubits is difficult to maintain for a long time. Once they are observed by external entities, the qubits will lose coherence.

In a computer, qubits will interact with the external environment and decoherent.The time from the process of quantum transition from coherent state to loss of coherent state is the decoherence time. If the decoherence time is not long enough, the quantum computer cannot calculate it.

Increasing the decoherence time is the difficulty of quantum chip technology, and it is also one of the problems that Chen Mo is currently studying and solving.

In addition to extending the decoherence time of qubits and realizing the preparation, measurement and manipulation of spin qubits, it is also the subject of Chen Mo's current research.

Among the technical theories that Chen Mo obtained from the Science and Technology Library, superconducting quantum interference is the best theoretical technology he can use to manipulate microscopic quantum states.

In addition, in terms of control accuracy, it is necessary to break through the fault-tolerant quantum threshold for quantum chips to succeed.

In order to ensure the effective execution of scalable quantum computing, the error rate of logical operations cannot exceed 10 orders of magnitude. In order to achieve this error tolerance rate, Chen Mo chose to use topological quantum error correction as his research direction.

Use the topological properties of quantum states for quantum error correction.

This theory is recorded in the quantum materials obtained by the scientific and technological library, and there are similar topological quantum error correction theories in real science. This is the highest error-tolerant quantum computing solution that can be achieved with the existing technology.

"Go to the laboratory."

Chen Mo stood up from the platform, asked Mo Nu to store the information on the quantum chip design, and walked towards the quantum laboratory.Now he is not sure whether the method is feasible, he needs to use experiments to verify his ideas and ideas.
