Provably secure and practical quantum key distribution over 307 km of optical fibre

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 in...
