The effect of the turbulent motion ocean on quantum communication based orbital angular momentum in an underwater channel is studied this work. Based power spectrum model turbulence proposed by Elamassie, quantitative relationships different parameters with single photon detection probability photons, capacity, key generation rate, concurrence two entangled photons are proposed. maximum entangl...
