The "chip ban" detonated the crisis
In May 2020, the United States issued a "chip ban", prohibiting companies worldwide from using US semiconductor technology and equipment, without permission, to Huawei Sell chips.
After the implementation of the "chip ban", all companies using American semiconductor technology and equipment have stopped cooperating with Huawei, which has plunged Huawei into an unprecedented "chip crisis".
Ren Zhengfei once said that my country has the world's top chip manufacturing and design capabilities, but it is unable to manufacture the high-end chips required by Huawei. The main reason is that photolithography machines and chemical materials are stuck.

At present, the overall level of my country's chips is lagging behind. This has to be admitted. However, the chips in my country are still traditional silicon-based chips.
The so-called silicon-based chip is made into monocrystalline silicon after a grain of sand is purified, and then processed through a multi-layer complex process, such as photolithography, etching, ion implantation, packaging and testing, etc. Silicon-based chips required in smart devices.
The current silicon-based chip technology is mainly monopolized by countries such as the United States, Japan and Europe, such as Japanese chip design architecture technology, photoresist , American chip design software, and European photolithography machines.

These countries mastering silicon-based chip technology established an alliance decades ago.And signed the " Wassenaar Agreement ", the agreement clearly pointed out that the sale of core silicon-based chip technology to my country is prohibited, which is the fundamental reason why my country's chips are still behind after rapid development.
Before Huawei is suppressed, we can still spend more money to buy the chips we need. However, the implementation of the chip ban has completely made us realize that we must have our own core chip technology.
After Huawei was sanctioned, my country has increased its investment in the development of silicon-based chips, such as the strong entry of the Chinese Academy of Sciences, the establishment of a chip university, and the creation of Oriental Core Port. In addition, my country has also increased its investment in future chips and achieved good results.
Chinese quantum chip achieves another breakthrough

Not long ago, my country's quantum computer "Nine Chapters" was born, and its performance completely defeated the American "Sycamore" quantum calculation formula. Our quantum supremacy.
Compared with traditional supercomputers, "Nine Chapters" have very powerful computing capabilities. "200 seconds is just a short moment, 600 million years is already the vicissitudes of life", this sentence expresses the calculation ability of the nine chapters very well. According to industry sources, "Nine Chapters" can simulate the explosion of the universe!
However, the current quantum computer is only a prototype, with very limited uses. The reason for this is mainly limited by quantum chips.
In order to commercialize quantum computers as soon as possible and make due contributions to the development of mankind, scientists from various countries are accelerating the research and development of quantum chips.

It is reported that scientists in the United States, Europe, Japan and South Korea have all made breakthroughs in the research and development of quantum chips, but there is still a long way to go before quantum chips are manufactured. R&D has encountered bottlenecks.
When these scientists scratched their heads for the development of quantum chips,Good news from my country's quantum chip!
Recently, the He Yu team of Southern University of Science and Technology officially announced that using the scanning tunneling microscope technology, it is possible to place a quantum dot composed of two atoms at a distance of 13nm with single-atom precision. It is reported that this technology can use off-the-shelf lithography machines and etching machines to manufacture quantum chips, without special research on a set of chip manufacturing technology.
To put it simply, my country has mastered the technology of 13nm quantum chips, and will soon be commercially available.
The Chinese scientist is a superman

Maybe you don't know much about He Yu, today I will briefly introduce it here.
He Yu, Associate Researcher at the Institute of Quantum Science and Engineering, Southern University of Science and Technology, under the tutelage of Professor Span6span Lu Chaoyang , Academician Pan Jianwei and Professor Michelle Y. Simmons. Those three of his teachers who are concerned about quantum technology must know that the world's quantum technology champion!
At present, the "Nine Chapters" believe that my country has established absolute quantum hegemony. It has also used quantum technology to build a very large quantum communication network, and has mastered 13nm quantum chip manufacturing technology, etc., which all prove that my country is in quantum In terms of technology, it has been a big step ahead of other countries.

It must be said that my country's development in the field of quantum technology has only taken more than ten years.
When Professor Marlan Scully, an American scientist, visited the University of Science and Technology of my country, he fully affirmed China's achievements in the quantum field and joked: Are all Chinese scientists superhuman? It only took more than ten years to finish our decades of work and lead us by a lot!
PS: Professor Marlan Scully, a member of the American Academy of Sciences, a famous quantum expert.

Not long ago,I saw such a video on a social platform. Chinese soldiers patrolled on a plateau at an altitude of more than 4,500 meters. Problems such as heavy snow, severe cold, and lack of oxygen made it very difficult for them to walk. After seeing this video, I remembered the environment we were in again, and there was only one sentence in my mind: there is no time for peace in the world, it's just that someone is carrying the weight for us!
In fact, whether a country is strong or not, science and technology are an important criterion for measuring a country's comprehensive national strength. Therefore, our scientists are also indispensable for our happy and worry-free life now!
