FIELD: quantum technology.
SUBSTANCE: invention relates to quantum key distribution, namely to relativistic quantum protocols. System of relativistic quantum key distribution, operating along an atmospheric channel, containing a source of attenuated radiation, at least one delay interferometer and a single-photon detector measuring the interference result in the interferometer, in which the receiving delay interferometer is corrected in phase using the Bayesian statistical method, based on the use of a single-photon photodetector as a source of an error signal.
EFFECT: technical result is the organization of adjustment of a receiving interferometer in a single-pass scheme of relativistic quantum key distribution using available resources in a system.
