We investigate the optical absorption and scattering prope rties of underwater media pertinent to our underwater quantum key distribution (QKD) channel model. With the vector radiative transfer the ory and Monte Carlo method, we calculate the bit rate, the fidelity, and the quantum bit error rate of photons when transmitting underwater. It can be obse rved from our simulations that maximally secure single photon underwate r BB84 QKD is feasible with a distance of about 125 m in the clearest… Expand
