| Abstract: | The effect of atmospheric turbulence on quantum optical communication systems based on angular momentum states of single photons is investigated and the detection probabilities of the orbital angular momentum of the photons propagation in slant atmospheric turbulence channel is modeled with Rytov approximation and modified yon Karman spectrum model of index - of- refraction fluctuation. The statistical averaging of the orbital angular momentum l of single photon in quantum eommunieatinn channel is given. |
