Abstract:
In this work we study the underwater optical channel, making a feasibility analysis on the development of a high-speed communication system with security guaranteed by Quantum Key Distribution (QKD) protocol. In particular, we introduce a new model for the attenuation of the underwater medium which includes the effect of turbulence within the marine environment.We report the performance of the system focusing on the most important figures of merit, such as the secret key rate of the quantum channel and the bit rate of the classical channel at the physical layer as a function of the total link range. We carried out these analyses depending on various environmental conditions, such as the geographical area, depth, path-loss and turbulence models. The communication protocols considered are the BB84 with time-bin encoding for QKD and baseband On-Off Keying (OOK) modulation for classical data communication for a maximum link range of 100 meters.
