Preface
In order to hinder the development of China's high-tech enterprises, the United States sanctioned Chinese companies in 2019 and sanctioned a new batch of Chinese companies this year.
Which Chinese companies has the U.S. sanctioned? What do these companies do?
Let the wind blow and the waves blow
On May 9 this year, the United States announced the latest sanctions list against Chinese companies, and this time there are 37 companies on the list, which are mainly related to several concerns of the United States.
In 2023, the "stray balloon" incident broke out in the American media, which made the Democrats and Republicans, who were still fighting for political power, immediately put down the quarrel at hand and pointed all the fingers at China.
It can be said that China has single-handedly helped the US political circles to unite and play up the "China threat theory" together, and whether China is innocent or not, the US media has achieved its desired goal.
However, in a responsible manner, the mainland has come forward to make relevant explanations, saying that the mainland has no intention of threatening US security.
Originally, this incident has been more than a year ago, but this year, the United States has never forgotten this incident because it is calm and light on the surface.
Because of the 37 companies sanctioned by the United States on the mainland, 8 Chinese companies are related to the "stray balloon" incident, and the United States still feels that it is not safe to do so, and even digs deep into which of these companies have ties with other companies.
After doing its homework, the United States found that these eight Chinese companies also had ties with three other Chinese companies, so they simply sanctioned these companies together and resolutely did not leave any trouble.
In addition to their sanctions, it is the relatively hot UAV companies in recent years, the mainland has obviously introduced relevant policies to prohibit the export of UAVs with strong carrying capacity, so as to maximize the export of UAVs for military operations in the cradle.
But the United States is still not at ease, thinking that the drone equipment used in Russia, and even the Russian drone manufacturers, have a certain connection with China, and feel that if it were not for China's drone companies, the Russian army would not be able to use such advanced drone equipment in the mountains.
As a result, the United States began to sanction 4 Chinese companies related to drone products, and DJI was not on the list, because DJI had been gloriously lying on the US sanctions list a few years earlier.
The batch of Chinese companies sanctioned by the United States this year are either related to the "stray balloon" of the United States or related to drones, there is nothing new, but the remaining 22 Chinese companies sanctioned by the United States give people a bright feeling.
These companies are all related to the field of quantum communication, and some companies even have the word "quantum" in their names, so even ordinary people can see at a glance that they are high-tech enterprises.

On May 6 this year, the mainland's University of Science and Technology of China made a major breakthrough in the field of quantum communication, earlier than the United States announced the list of sanctions against Chinese quantum communication companies.

In other words, the United States was afraid of China's achievements in the field of quantum communications, so it hurriedly collected information on relevant mainland enterprises, and finally made a list of sanctions.
The quantum communication technology achievements announced by the mainland are not low-end technologies without thresholds, but mid-end technologies that are mature enough to create economic value for the mainland.

I didn't move
The mainland has developed a new platform for the quantum Hall effect, mainly to transform quantum technology from theory to practice.
When it comes to quantum technology, it may be a little unfamiliar to everyone, but we all know a little bit about communication technology.
Quantum communication technology is simply a kind of communication technology, and the biggest difference between it and ordinary communication technology is that it has higher work efficiency and allows users to be safer in the process of using this technology.
In other words, a call based on quantum communication is equivalent to an encrypted call, and peers whose technology does not reach a certain height cannot be decrypted.
As far as the world can see, only European countries like the United Kingdom, the United States and the mainland are researching quantum communication technology, and the scientific and technological level of other countries cannot support research in this field.
There are enterprises in the mainland that study quantum communication technology, as well as research units such as the University of Science and Technology of China, but the main force in the research of this technology is still the research unit, because it is difficult to realize the early stage of technology research and development, and generally enterprises without strong financial support dare not take risks to engage in research.
But Britain is different, they know that quantum communication technology will be put on the market sooner or later to make money, and simply support their own enterprises to engage in research, as soon as they make a move, it will be 2.5 billion pounds of government investment.
After seeing the government's move, their country's investors invested 1 billion pounds, which became a strong backing for the development of quantum technology in the United Kingdom, in addition to the state.
Countries such as the United Kingdom and the United States have never thought of giving up on quantum technology, and in 2023, the American research team also observed fractional quantum anomalous Hall states.
The existence of fractional quantum anomalous Hall states is mainly to provide strong technical support for the commercialization of quantum communication.
Originally, the mainland's research and development in this field was later than that of the United States, but the research results obtained by the mainland's research team were no less than those of the United States.
For example, in 2013 and 2023, the continent observed integer quants and fractional quantum anomalous Hall states respectively, which have gradually changed from following the pace of the United States to infinitely narrowing the gap between the United States and the United States' technological level.
For example, the quantum secure communication developed by the mainland has gradually matured, and the mainland's quantum communication network technology is being promoted by the state to Beijing-Tianjin-Hebei, Yangtze River Delta, Guangdong, Hong Kong, Macao, Chengdu and Chongqing.
With the support of the mainland's investment in the quantum field of 15 billion US dollars (the world's first), accounting for almost half of the global investment scale, the mainland has launched products such as "quantum secret talk" and "national shield secret language headset".
The existence of these products makes it extremely difficult for criminals to threaten the mainland's information security, because they can detect the listening equipment during the communication process, so that the relevant personnel can respond in a timely manner.
However, the whole world is separating and researching quantum communication-related technologies, and in 2028, which country's quantum communication computers can make money commercially depends on their own capabilities.
The computing speed of this kind of computer is too fast, for example, if a job is handed over to the world's top computer, it will take about 50,000 years to complete the work, but the quantum communication computer can complete it in only 4 hours.
It can be said that whichever country takes the lead in mastering quantum communication computer technology will be able to lead other countries in the field of scientific and technological development, and the mainland's quantum communication technology is developing rapidly, so the United States has to guard against it.
Science and technology are the primary productive forces, and we must pay close attention to the mainland's scientific research personnel and the scientific research environment and assist them in creating more research results, because these research projects can benefit the people after they reach a certain level of maturity.
