China positions Hong Kong for quantum

China is trying to turn Hong Kong into its outward-facing base for quantum technology, even as Washington expands export controls and sanctions. (scmp.com) Quantum technology uses the behavior of matter and light at very small scales to build new computers, sensors and secure communications systems. A November 2025 report by the United States-China Economic and Security Review Commission said the field spans computing, sensing and communications and is now part of direct United States-China competition. (uscc.gov) The immediate push runs through the Hetao Shenzhen-Hong Kong Science and Technology Innovation Cooperation Zone, a cross-border project that Beijing and Shenzhen have promoted as a joint science platform. Origin Quantum co-founder Guo Guoping told the South China Morning Post that Hetao could serve as a window connecting Chinese quantum technology to global networks. (scmp.com) (htcz.sz.gov.cn) That plan did not start this month. In August 2023, authorities said the Hetao zone would support Shenzhen and Hong Kong in jointly building a “Quantum Valley” with domestic and foreign universities and research institutes. (htcz.sz.gov.cn) Hong Kong also rewired its own research system in 2025. The city’s revamped State Key Laboratory program added three new laboratories, including the State Key Laboratory of Optical Quantum Materials at the University of Hong Kong and the State Key Laboratory of Quantum Information Technologies and Materials at the Chinese University of Hong Kong. (cpr.cuhk.edu.hk) (itc.gov.hk) (hku.hk) Beijing formally presented plaques for 15 State Key Laboratories in Hong Kong on August 25, 2025, after the labs began operating on July 1, 2025. Hong Kong’s Innovation and Technology Commission said the scheme is managed by China’s Ministry of Science and Technology and aligned with the national development plan. (news.gov.hk) (itc.gov.hk) The city is also trying to make itself visible as a meeting place for overseas researchers. The Hong Kong Institute of Quantum Science and Technology co-hosted the American Physical Society Global Physics Summit 2026 Hong Kong Meeting from March 23 to 27 at the Hong Kong Productivity Council building, with online links to the main summit held March 15 to 20. (iq.hku.hk) Officials are pairing that convening role with claims of technical progress inside Hong Kong. In February 2026, Hong Kong Polytechnic University said its team had completed the city’s first urban chip-based quantum key distribution test over a 55-kilometre commercial fibre loop, aimed at future secure communications networks. (polyu.edu.hk) The sanctions backdrop is central to the pitch. The South China Morning Post reported that Hong Kong has more than 300 entities blacklisted by Washington, while the city’s Innovation, Technology and Industry Bureau said on April 8 that United States restrictions would not deter Hong Kong’s “march towards becoming an international I&T hub.” (scmp.com) The argument from Beijing and Hong Kong is that the city can still offer something sanctions do not fully block: universities, conferences, finance, legal infrastructure and cross-border access to Shenzhen. The test for that strategy is whether Hong Kong becomes a place where quantum research, standards-setting and supply-chain ties are actually built, not just announced. (scmp.com) (htcz.sz.gov.cn)
