My Super Black Technology Empire

After all, today's quantum computers do not have quantum chips, but like the first computer, a large number of transistors are used to undertake data calculations.

Why is the computing power of hundreds of quantum transistors dozens of times greater than the computing power of today's super servers?

The essential difference is that quantum chips perform quantum calculations, while digital integrated circuit chips perform digital calculations.

In digital integrated circuit chips, 0 and 1 in binary arithmetic are represented by high and low levels, and Rocky operations are performed through logic gates composed of triodes and mos tubes.

What needs to be completed in the quantum chip is quantum computing. Two different quantum states are used to represent 0 and 1 in the quantum algorithm. The operation also requires corresponding quantum logic gates. Compared with digital circuits, superposition operations can be performed. and superposition storage.

For a function f(X), 100 X values ​​need to be brought in to obtain 100 results. In classical calculation, 100 calculations need to be performed, and once X is added, it needs to be calculated once.

But in quantum computing, it only needs to be calculated once.

Since in the process of quantum computing, the computing unit is a qubit composed of quantum states, all X values ​​are quantized.

100 X values ​​can be superimposed into a mixed state. If it is brought into the quantum chip and calculated once, a mixed state of 100 results can be obtained, and after corresponding measurement, the result of the corresponding value can be found.

Therefore, the corresponding superposition state storage is also well understood. 100 X values ​​can be mixed into one state for storage, and 100 storage devices are not required. Therefore, in terms of computing efficiency, this is also a quantum computer that is tens of thousands faster than an ordinary computer. times the reason.

The efficiency of each quantum transistor is tens of millions of times that of ordinary electronic transistors, so with only a few hundred quantum transistors, the computing power is dozens of times faster than today's top servers.

So if it is made into a quantum chip, if hundreds of millions of quantum transistors are integrated in a chip, how terrifying will the computing power be?

At present, quantum chips have also been manufactured in the world, but because of technological problems, and there is no way to integrate quantum transistors in a chip, and there is no corresponding software and algorithm to support them, so it is not currently available for civilian use, and there is no Ordinary computers are so powerful.

However, there are still many people who are going further and further on the road of quantum chips. At present, superconducting systems, semiconductor systems, and quantum well systems all have corresponding quantum chip research, and are exploring the direction of large-scale inheritance.

At present, the technical route based on superconducting Josephson junction system is at the forefront at the current stage, but in recent years, semiconductor-based gated quantum dot technology has developed rapidly, so except that Datang Technology has found the right path for quantum computers, other People have not made any conclusions about which technical route quantum computing will take.

The Chief Scientist of Original Quantum, Professor Guo Guoping of Huaxia University of Science and Technology, has presided over and undertaken the national key research and development programs of "solid-state quantum chips" and "semiconductor quantum chips" in my country since 2010.

The first-generation semiconductor bit quantum chip-Xuanwei, which was jointly developed by Benyuan Quantum and Huaxia University of Science and Technology, can be well combined and utilize modern semiconductor microelectronics manufacturing processes by using semiconductor quantum dot systems.

Prepared by purely electronic control, the control and reading of qubits are more stable, and ultra-fast and precise control and long-term coherent fast control coding can be realized.

Kuafu, the first generation of superconducting six-bit quantum chip independently developed by Origin Quantum, has the fidelity of a single quantum logic gate as high as 99.7%, which is only one step away from the current international level (99.94%).

In order to improve the efficiency of reading quantum chip information, Origin Quantum has independently developed a variety of quantum parametric amplifiers.

Among them, the quantum impedance matching amplifier QriginQ-IMPA-6650 can achieve a gain of 15-30db,

In the high bandwidth mode, the gain of 20dB can be achieved, and the gain bandwidth is higher than 400MHZ.

Its noise is as low as the standard quantum limit, and it is the best quantum parametric amplifier of the same type in China.

At the same time, Origin Quantum is developing a quantum traveling wave parametric amplifier with higher gain bandwidth and more stable performance, which is expected to be read in parallel with at least 20 qubits.

If it is necessary to package the chip, Ye Fan also considers referring to their packaging technology, which may be used when packaging quantum transistors in the future.

Origin Quantum has developed a variety of three-dimensional packaging technologies based on quantum computing chips and quantum parametric amplifiers, which can greatly reduce signal crosstalk and suppress environmental noise.

For example, the three-dimensional packaging of IMPA chips can be used to complete the packaging of IMPA chips, and provide test interfaces at room temperature and low temperature.

The newly developed third-generation fully-enclosed quantum chip packaging can be used to complete the packaging of 1-6-bit quantum CPUs, and provides room temperature and extremely low temperature test interfaces.

Unlike Ye Fan, they have systematic guidance and can exchange various technologies from the system.

For a technology that is too ordinary in Ye Fan's eyes, it is very difficult to develop a correct path in the eyes of others.

What's more, the development of quantum chips is more difficult and arduous than the development of traditional chips, or even the miniaturization of quantum transistors.

They not only need to tackle the quantum chip process, but also continuously improve the principle design of the quantum chip.

It is not good for the development and progress of science and technology.

It is impossible to rely on Ye Fan to promote the scientific and technological progress of the entire human being. After all, he is not a saint, he is just an ordinary person.

He didn't want to engage in the practice of a great sage who gathered tens of thousands of great powers in one body. For the technological progress of a race, one person can only play the role of a mentor.

What Ye Fan has to do is to constantly guide scientists and even ordinary people to stimulate their willingness to research and develop science and technology, instead of looking at money in everything like today's reality.

In fact, if human beings leave the earth and enter the galaxy age, things like money will really not be as important as they are now. At that time, the existing currency system may be upgraded or even collapsed directly.

After all, the resources in the universe are very rich. When human beings acquire a large amount of resources, it will definitely have a huge impact on the existing currency system.

So money is meaningless at all, resources, science and research and development are the most important factors to ensure that human beings can survive in this dark universe.
