Quantum computing is poised to unleash innovation across various sectors, from materials science to pharmaceutical and medical research, finance, logistics, and even climate change management. Quantum computing also has the potential to provide the backbone for future artificial intelligence and autonomous systems that cannot be realized with digital hardware alone, while quantum communication can strengthen security in cyberspace. For these reasons, quantum technologies feature prominently in the emerging technologies race between the United States and China. In this policy brief, IGCC postdoctoral fellow Juljan Krause analyzes China’s advances in quantum communication, which aim to signal China’s technological leadership while protecting Chinese communications from foreign surveillance. He argues that Chinese leadership in quantum communication will have strategic repercussions, particularly as it is likely to give China’s efforts to shape global industry standards additional momentum. Even if quantum communication has no immediate military implications, policymakers should consider how the technology could embolden China further.
