Effects of ocean turbulence on photon orbital angular momentum quantum communication

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 entanglement distance photon-pairs further universal decay turbulence. results show that photon, and decrease increase dissipation rate kinetic energy mean-squared temperature. influence temperature salinity balance parameter performance significantly under condition whether stable stratification seawater assumed or not. In environment, increasing initial number signal can improve distribution resistance to decay.
