Abstract: This paper deals with possibility of implementation of quantum key distribution algorithm through turbulent atmosphere. Beam wandering is considered as the main perturbation. For description of the density matrix, the Glauber-Sudarshan P-function technique is used. The probabilities of detectors triggering are determined.

Keywords: quantum bit, gaussian beam, entanglement, quantum key distribution.
