Free space relativistic quantum cryptography with faint laser pulses

Laser Physics Letters. 2013. Vol. 10. P. 075205-075211.
Potapova T. A., Molotkov S.

A new protocol for quantum key distribution through empty space is proposed. Apart from the quantum mechanical restrictions on distinguishability of non-orthogonal states, the protocol employs additional restrictions imposed by special relativity. The protocol ensures generation of a secure key even for the source generating non-strictly single-photon quantum states and for arbitrary losses in quantum communication channel.
