As a pivotal hub fostering international research collaboration between the Greater Bay Area and the rest of the world, Hong Kong serves as a unique intermediary in driving the innovation and translation of quantum technologies. The "International Conference on Quantum Technology 2025" (Quantum HK 2025), hosted by The Hong Kong Polytechnic University (PolyU), has recently concluded, having attracted more than 200 experts, scholars, researchers and industry leaders. The Conference fostered in-depth discussion on cutting-edge breakthroughs and future developments in quantum technologies, further expanding the breadth and depth of academic exchange and academia-industry collaboration. The event's co-organisers were The University of Hong Kong (HKU), The Chinese University of Hong Kong (CUHK), The Hong Kong University of Science and Technology, City University of Hong Kong (CityUHK), the Physical Society of Hong Kong, and the Beijing-Hong Kong Academic Exchange Centre.
Prof. Christopher CHAO, PolyU Senior Vice President (Research and Innovation) remarked, "As this year marks the International Year of Quantum Science and Technology, quantum technologies have become a key agenda item of global interest. Over the past year, breakthroughs in quantum computer, quantum communication and quantum metrology have laid important foundations for the application of artificial intelligence and secure communications. PolyU has successfully established Hong Kong's first quantum chip-based communication network, completing a quantum encrypted transmission test that spanned a 55km-long optical fibre network—demonstrating Hong Kong's leadership in quantum innovation. Looking ahead, PolyU will continue to nurture talent, foster interdisciplinary collaboration and accelerate the translation of quantum technology scientific achievements into societal applications, contributing to global quantum development."
Prof. Ai-Qun LIU, the Conference Co-Chairman, Director of the Research Institute for Quantum Technology, Chair Professor of the Department of Electrical and Electronic Engineering, and Hong Kong Global STEM Scholar, noted, "This conference gathered experts bringing insights from academia and industry, building an interdisciplinary platform for exchange and collaboration in quantum technologies. Moving forward, it will continue to unite diverse stakeholders to expedite research translation and industrialisation, injecting new momentum into the development of quantum technologies in Hong Kong, the Greater Bay Area and the Nation."
The Conference was co-chaired by Prof. Ai-Qun Liu, Prof. Oscar DAHLSTEN and Prof. Din-Ping CAI from CityUHK, as well as Prof. Giulio CHIRIBELLA from HKU.
There were also multiple keynote talks aimed at facilitating in-depth discussions on quantum computing, quantum information security and metrology. The speakers included: Academician Dapeng YU from the Shenzhen Institute for Quantum Science and Engineering; Prof. Xicheng ZHANG from the University of Rochester; Prof. Guilu LONG from Tsinghua University; Prof. Leong Chuan KWEK from Nanyang Technological University; Prof. Abolfazl BAYAT from the University of Electronic Science and Technology of China; Prof. Tim BYRNES from NYU Shanghai; Prof. Yanoar P. SARWONO from the Agency for Science, Technology and Research, Singapore; Prof. Qi ZHAO from HKU; and Prof. Haidong YUAN from CUHK.
Meanwhile, representatives from other leading organisations and companies—including Huawei, QBosoN, SpinQ, Tencent Quantum Lab and Xuntai Quantum Technology—engaged in roundtable discussions, focusing on industrialisation of research outcomes. They also offered forward-looking recommendations on standardisation, modularisation and scalability in quantum technologies, while also emphasising the need to accelerate the development of a stable and multi-tier talent pipeline to effectively support innovation and growth in the quantum industry.
