How to view the US blockade of Chinese quantum research

The US Department of Commerce's Bureau of Industry and Security (BIS) announced the addition of 37 Chinese entities to the list of export controlled entities. This includes 22 quantum industry research institutions. The sanctions have a wide range of targets and clear priorities, and China's core quantum research units have been destroyed. In this regard, the US Department of Commerce gave the reason that the above-mentioned Chinese quantum institutions have played a key role in advancing China's quantum technology capabilities, which could have serious implications for US national security.

The reason why the United States once again wields the big stick of sanctions to the field of quantum research is that in recent years, with quantum technologies such as quantum cryptography and quantum computing making major breakthroughs, China's quantum technology has shown a booming trend of development, catching up with the leading position of the United States in the quantum industry, and the United States is not confident that it can always maintain its leading position, and political repression has become the priority choice of the United States. After all, this is also a common tactic used by the United States against China's high-tech industry. There is no doubt that the US sanctions have brought serious challenges to China's quantum technology industry, mainly depriving trade opportunities and curbing the technology research and development process. After being included in the entity list of the United States, the relevant enterprises are not allowed to purchase equipment and components and other materials from the United States without obtaining a license. This in fact deprives these quantum research institutions of trade opportunities in the United States, making it difficult for them to obtain the materials they need from the United States, thus affecting the technology research and development process, and thus affecting global academic exchanges and progress.

In addition to the blow to the Chinese market, the United States sanctions have also brought a series of impacts on the global quantum market: First, hinder international exchanges and cooperation: Chinese quantum research institutions are included in the "entity list", which will make it difficult to obtain American technologies and products, which will seriously hinder the exchanges and cooperation between China and the United States in the field of quantum science and technology. The obstruction of this cooperation not only affects the research progress of both sides, but also may affect the development process of global quantum science and technology. The second is to delay the development of global quantum technology: China and the United States are the main forces of global quantum technology research, and the obstruction of scientific and technological cooperation between the two countries will inevitably delay the development process of global quantum technology. This may delay the application of quantum technology, which in turn affects the development of related industries. The third is to change the market pattern: sanctions may cause some Chinese quantum enterprises that originally relied on US technology and products to turn to other markets for cooperation, thus changing the global quantum market pattern. At the same time, it may also prompt other countries to strengthen cooperation in the field of quantum science and technology to meet the challenges posed by Sino-US competition.

All along, based on its own interests, the United States has generalized the concept of national security, arbitrarily formulated, changed and interpreted rules, and carried out targeted attacks on Chinese high-tech enterprises, which has brought negative impacts on the development and progress of science and technology. But in the face of sanctions, China is likely to increase support for the quantum technology industry and encourage domestic institutions to carry out independent innovation. This helps to enhance China's competitiveness in the global quantum technology field and may push China to make more breakthroughs in the field of quantum science and technology. Because the key core technology is not come, can not buy, can not negotiate, only through their own hard work and innovation, in order to win a greater strategic space. In short, the impact of the US sanctions is complex and far-reaching, and it requires concerted efforts from all parties to meet the challenges and promote the development of global quantum technology.
