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 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.
Quantum research of China with the West is declining
After the number of EU countries’ joint publications with China-based authors grew between 2017 and 2020, in 2023, less than 10 percent of quantum-related papers published in EU countries were co-authored with Chinese researchers. This is not because China fell behind. Quite the contrary, China increased its portion of most-cited papers in the field over the same period. Instead, it shows that political and security concerns are slowing collaboration.

Tech progress
- A team at the University of Science and Technology of China presented a new quantum chip, Zuchongzhi 3.0, with 105 qubits. The chip broke a record for quantum computing previously held by Google. (Source (EN): Quantum Insider, 04.03.2025, Source (CN): CAS, 03.03.2025)
Domestic dynamics
- Hong Kong-listed investment company Guofu subsidiary Fuqiang Asset Management established an independent portfolio company (SPC) that will invest in quantum tech (Source (CN): Sina Finance, 05.02.2025)
- Quantum is becoming a commercial industry, suggests a white paper by the Chinese Academy of ICT, a think tank under the Ministry of Industry and Information Technology. Worldwide, there is growth in the number of quantum-related companies, the value of investments, and standardization activity, notes the report, providing an overview of Chinese standards (Source (CN): CAICT, 26.12.2024)
- China Telecom became the largest shareholder of QuantumCTek, China’s leading firm in quantum key distribution. The state-owned China Telecom had gradually increased its investments to support “the future industries”. It now owns 22 percent of the stock and through an agreement with other shareholders it controls 40 percent of the voting rights. This signals further industrialization of the quantum communication industry. (Source (CN): 21jingji, 10.01.2025)
