Quantum
Quantum technologies are emerging as a key subject of global power competition due to their potential military applications and ability to fundamentally transform people’s lives. Quantum effects can overcome limitations of digital technologies, solve computational problems that take impossibly long using traditional computers and transmit information over long distances without the risk of being intercepted. China hopes quantum technologies will allow it to leapfrog Western rivals.
China and the US are locked in a tight race for supremacy in quantum technologies. Through sustained government investment, China has achieved a number of firsts, including developing and launching the first quantum satellite, Micius.
While China has so far led in quantum communication, which enables secure communication over long distances, the US still leads in quantum computation.
China’s quantum technology development is a major result of mission-driven innovation. In the US, private companies like IBM dominate the race. So far at least, Chinese quantum technology companies and researchers have relied on government funding. Instead of large digital companies, startups founded by people with university affiliations, and usually funded by local or central government funds, dominate the landscape.
Quantum technologies are also a major area of international collaboration. Micius, the quantum satellite, was developed in cooperation with the University of Vienna, with future communication tests taking place between China and Russia. Many quantum technologies are still far from being market-ready but could provide decisive advantages to a military using them. As such, quantum research is at the forefront of discussions about research security in Europe.

China ramps up investment in quantum as a "future industry"
China is showing renewed interest in quantum technologies, ramping up its investment to a total of CNY 3.2 billion in the first three months of 2026, exceeding the total for all of 2025. This comes after China named quantum as a “future industry” in its 15th Five-Year Plan. After a period in which big Chinese tech companies like Baidu and Tencent scaled back or opted out of quantum investment, large- scale capital is now flowing back into the sector, suggesting a renewed focus on moving the technology from the lab to commercial applications. Compared with other future industries such as 6G or nuclear fusion, quantum is attracting strong investment momentum.
China has built the world's largest quantum communication network
China completed the first phase of a large state-led project on quantum secure communication in 2020. It is the largest such network in the world by far, with an overall length over 12,000 kilometers and nodes in most major Chinese cities. Additionally, two quantum satellites link up the extremes of the network. Major research institutes and firms are concentrated around the network, illustrating close ties between research, state and industry.
China's policies mention quantum technology more often
Chinese policies and regulations show an increase in mentions of “quantum” (量子) even before the launch of the megaproject for quantum technologies in 2016. The Politburo declared quantum an important front in the global S&T competition in 2020, triggering a surge in official documents mentioning the term. Mentions of “quantum” even outpaced those of “science and technology”. This illustrates how the technology has gained importance for China’s leaders.
