China’s quest for quantum advantage—Strategic and defense innovation at a new frontier

China has prioritized quantum science and technology as a critical frontier for its national security and development. To date, Chinese research has already reached a leading position within the discipline, enabled by state support and funding, as well as the recruitment and cultivation of talent. The rapid advances on this front can provide a valuable illustration of the dynamics of China’s evolving innovation ecosystem, including the increased prominence of leading technology companies, and even start-ups, as serious contenders. China’s strategy of military–civil fusion, which aims to create a more integrated ecosystem in science and technology, can contribute to enabling progress in dual-use developments. This case study draws upon the shared framework for this special issue, which provides a method by which to consider the factors that enable defense innovation. Looking forward, these advances could prove consequential for the future strategic balance between China and the United States.
