An ongoing record of China's quantum computing, communications, sensing and the infrastructure behind them. We distinguish peer-reviewed experiments from deployed systems, institutional announcements and prospective applications.
Ordered by research publication date. Historical records are marked as retrospectively entered; experimental results are not presented as deployed capabilities.
A Nature Photonics study reports free-space twin-field quantum key distribution across 14.2 km of urban atmospheric channels, addressing a technical obstacle relevant to future satellite links.
A Nature paper reports a programmable 8,176-mode Jiuzhang 4.0 photonic processor using 1,024 squeezed states and sampling events involving up to 3,050 detected photons.
A Nature paper reports a large-scale quantum communications experiment using integrated photonics, adding a research milestone distinct from China's deployed trusted-relay networks.
A peer-reviewed paper describes a Chinese quantum key distribution network with approximately 10,103 km of fibre backbone, 145 nodes, 20 metropolitan networks and six Jinan-1 satellite ground stations.
