Influence of Oceanic Turbulence on the Performance of Underwater Quantum Satellite Communication

Abstract

Oceanic turbulence is one of the important factors that affect the transmission of quantum optical signals in the seawater medium. However, up to now, none research on the influence of oceanic turbulence on the parameters of quantum communication channel is in progress. In order to fill such vacancies, we simulate in this paper the relationship of oceanic turbulence parameters to the optical wave structure function and the optical wave spatial coherence length to acquire the relationship between the oceanic turbulence intensity and oceanic turbulence parameters. Then, the relationships between the oceanic turbulence parameters and the channel entanglement, the bit-flip channel capacity, and the channel error rate are respectively established and simulated. The simulation results provide a reference for underwater quantum communication with the influence of oceanic turbulence.
