Provably secure and practical quantum key distribution over 307 km of optical fibre
Open accessAbstract
A discrete-variable quantum key distribution system that is capable of distributing a provably-secure cryptographic key over 307 kilometres is demonstrated at a telecom wavelength. Proposed in 1984, quantum key distribution (QKD) allows two users to exchange provably secure keys via a potentially insecure quantum channel1. Since then, QKD has attracted much attention and significant progress has been made both in theory and practice2,3. On the application front, however, the operating distance of practical fibre-based QKD systems is limited to about 150 km (ref. 4), mainly due to the high background noise of practical single-photon detectors5,6 and inefficient finite-key security analysis7,8,9. Here, we present, for the first time, a compact and autonomous QKD system that is capable of distributing provably secure cryptographic keys over 307 km of optical fibre. This is achieved by using semiconductor single-photon detectors with record low background noise10 and a novel finite-key security analysis, which is efficient even for short key lengths. This demonstrates the feasibility of practical long-distance QKD based on standard fibre-optic telecom components.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
