Xu Chuan entered his office to study things. Fan Pengyue didn't care at first, thinking that he would come out soon.

As a result, it was not until the next day that he suddenly remembered this during the meeting.

I took out my cell phone and called, but I found that the junior brother had already run back to his villa.

In the study, Xu Chuan hung up the phone, looked at the manuscript paper on the table, which was already covered with dense characters, and continued to study.

The inspiration has been captured, and he thought of doing everything in one go and directly perfecting this theory.

......

"......... Considering the regular placement of dopants in the lattice of the spatial group (SG), this reduces symmetry to CUC143, while the double-band and four-band models are characterized by symmetrically enhanced double Weyl points at $\Gamma$ and A..."

"The excellent consistency of the high-temperature copper-carbon-silver composite material after the introduction of Cu atoms into magnetic wells in density functional theory (DFT) calculations provides evidence that the minimum topological band at the Fermi level can be achieved in doped materials."

"In theory, this is enough to provide a foundation for building topological quantum materials."

Looking at the words on the manuscript paper, Xu Chuan's eyes showed a hint of satisfaction.

After three days of forgetting to eat and staying up late, he seized the trace of accidental inspiration and spread it out and extended it in full. Based on the theory of strongly related electronic unified framework, he incorporated topological states into it.

Exploring the generation mechanism and characteristics of topological states in strong correlation systems provides a theoretical basis for realizing new quantum devices.

Although the theory and application are still far apart, with the guidance of theoretical foundation, the direction of application progress is already clear.

It was like a ship sailing on the sea that encountered a storm. Between the waves and hurricanes, I saw the bright lighthouse on the edge of the coast, and had a clear direction to move forward.

With satisfaction, Xu Chuan stood up and moved his muscles and bones.

The crackling sound of joints sounded, and he sat down again to sort out the manuscript paper on the table.

Studying the generation mechanism and characteristics of topological states can actually be regarded as a continuation of the theory of strongly correlated electronics' large unified framework.

However, he would probably not publish this research paper.

Because it is of great importance.

Papers that provide a theoretical basis for the structural materials of quantum chips, no matter which country it is published, it is the subject of national key confidentiality research.

After sorting out the manuscript paper and putting it into the drawer, Xu Chuan leaned on the back of the chair and stared at the bookshelf not far away and began to think.

With his research paper on the generation mechanism and characteristics of topological states, the development of quantum computers should be able to speed up some steps.

The development of quantum chips and quantum technologies is a future trend and a shortcut for China to overtake in the chip field.

As for traditional silicon-based chips, to be honest, there is no chance in this regard.

It is not only because Western countries led by the United States have been working on silicon-based chips for decades and have established a complete set of rules and advanced lithography technology, which has led to other countries being able to catch up and not surpass the outside world; there is also the reason why silicon-based chips are almost at the end.

Traditional chips have always been mainly silicon materials, but with the continuous improvement of chip technology, silicon-based chips are gradually approaching its limit.

At present, companies such as AMSL, TSMC, etc. have achieved the ability to produce three-nanometer or even two-nanometer chips.

But for silicon-based chips, one nanometer is its theoretical limit.

The first reason is that the size of silicon atoms is only 0.12 nanometers. According to the size of silicon atoms, once the chip process reaches one nanometer, you can basically not put down more transistors.

Therefore, traditional silicon grease chips have basically reached their limit. If more transistors are forced to be added after 1nm, various problems will arise in the performance of the chip.

The second reason is the quantum tunneling effect, which is the biggest factor limiting the development of silicon-based chips at present.

The so-called tunneling effect is simply a phenomenon in which microscopic particles, such as electrons, can directly pass through obstacles.

Specifically on the chip, when the chip process is small enough, the electrons that originally flow normally in the circuit will not flow honestly according to the route, but will pass through the semiconductor gate and flow everywhere, eventually leading to various problems such as leakage.

Simply put, it is like a person who has learned the art of passing through the wall and directly penetrates from one side of the wall to the other side.

In fact, this phenomenon does not refer to the effect that occurs when a silicon-based chip reaches one nanometer.

This leakage occurred in silicon-based chips when the chip reached 20 nanometers.

However, some chip manufacturers including TSMC improved this problem later after improving the process.

Later, when it was between 7 nanometers and 5 nanometers, this phenomenon reappeared, and ASML solved this problem by inventing the EUV lithography machine, which greatly improved the lithography capability.

However, as the chip process becomes smaller and smaller in the future, various problems caused by the quantum tunneling effect will gradually be exposed when traditional silicon-based chips reach 2 nanometers.

With the sign of one nanometer, even if some chip manufacturers can break through this mark, the overall chip performance will not be excellent in theory, or even be too stable, and various problems may arise.

Perhaps in this process, scientists will find various ways to solve this problem.

But the limitation of silicon-based materials itself lies there, and its development potential is limited.

Finding a substitute material or developing other discovered computers is something the chip and computer industry has been doing.

This chapter is not over, please click on the next page to continue reading! Quantum chips and quantum computers are undoubtedly the most important part of the future development route.

In this regard, even carbon-based chips with the greatest possibility to replace silicon-based chips are slightly less important.

After all, today's quantum computers have built a fairly complete theoretical basis and even realized physical computers that manipulate two-bit quantitative sub-bits, with a bright future in development.

As for the trouble, it lies in how to manipulate qubits and store information.

The theoretical paper on the generation mechanism and characteristics of topological states in his hand can solve this problem to a large extent.

This means that the number of bit manipulations of quantum computers can span three or even four digits.

Although traditional silicon-based chip computers often have tens of billions of transistors, the number of qubits sounds pitiful.

But in fact, the two cannot be compared at all.

If you have to PK, the computing power of a 30-qubit quantum computer is almost the same as that of a classic computer with trillions of floating-point operations per second.

The computing power of quantum computers increases with the manipulation index of quantum bits.

According to scientists, a 100-bit quantum computer will surpass the current strongest supercomputer when dealing with some specific problems.

If the computing bits of quantum computers can be increased to 500, then this computer will beat all current supercomputers in all aspects.

Of course, these are all theoretically based, and as for the specific actual situation, I don’t know yet.

However, the tempting prospects shown in theory naturally attracted countless countries and scientific institutions to focus on this.

Xu Chuan is no exception, especially since he still controls such a big killing weapon.

But what he is considering is whether to cooperate with the country to develop the field of quantum computers, build rules, and control quantum hegemony, or to continue researching it yourself.

Each has its own advantages and disadvantages, and it is indeed difficult for people to make a choice.

.........

After thinking for a while, Xu Chuan shook his head and threw away the thoughts in his mind.

Let’s take a step first. He can’t take any time to do this at the moment when the development of quantum computers is developing.

The miniaturized controlled nuclear fusion technology and aerospace engine have not been completed yet. The most important energy is to focus on this first.

After cleaning up the mess on the desk, Xu Chuan stood up, took a shower and rushed to the Chuanhai Materials Research Institute.

Superconducting materials with high critical magnetic fields have been supported by data in simulation experiments, and then they are naturally prepared through real experiments.

Originally, this work should have started three days ago, but he studied it in the villa for three days due to some unexpected inspiration. Fan Pengyue did not receive the instructions and did not dare to start without authorization, so he delayed it for three days.

However, Xu Chuan didn't care too much. These three days were totally worth it.

When he entered the laboratory and put on his work clothes, he found two formal researchers as assistants and began to prepare high-temperature copper-carbon-silver composite superconducting materials that introduced resistant to strong magnetic mechanisms.

In the early stages of preparing this improved superconducting material, there is not much difference in the steps.

The raw materials with high purity, good crystallization structure and controllable particle size are produced through vacuum metallurgy equipment, which is the basis for the preparation of copper-carbon-silver composite materials.

Then, using an RF magnetron sputtering device, the prepared nanomaterial was sputtered onto the SrTiO3 substrate to form a thin film.

And from here on, it is the turning point.

In the original high-temperature copper-carbon silver superconducting materials, 2% volume fraction multi-walled carbon nanotubes (CNTs) and surface-plated Cu-modified carbon nanotubes are needed to be added as reinforced phases.

However, in strengthening superconductors, it is necessary to introduce excess Cu nanoparticles and guide Cu atoms to form spins under high temperature and high pressure conditions through current stimulation and hybridize with C atoms to form orbitals to improve the structure of the material surface.

The main purpose of this step is to dopant Cu atoms in excess Cu nanoparticles into holes, thereby producing non-trivial quantum phenomena and promoting the generation of magnetic wells.

Simply put, the generation of magnetic traps requires the replenishment of energy from the outside world, and high temperature, high pressure, electrical conductivity and other methods are supplementary means and means to adjust the spin angle of Cu atoms.

This is one of the common methods for optimizing the performance and microstructure of nanoscale materials and superconducting materials.

In addition to high temperature and high pressure, there are also methods such as osmotic growth, solution method, vapor deposition method, physical deposition method, etc.

However, due to the need for additional energy replenishment, these methods are probably not suitable for superconductors that strengthen critical magnetic fields.

If the high-temperature and high-pressure guidance method is not suitable for improved superconducting materials, the only remaining way is probably to be completed through an ion implanter.

However, the energy level of the ion implanter is too high, which will damage the superconductor to a large extent. Not only will it reduce performance, industrial mass production is also a very troublesome thing.

After all, this is the preparation of raw materials, not semiconductor production, so you have to consider the cost-effectiveness and the difficulty of preparation.
