Örnek Metin	In this paper, we study the effect of various transmitter and receiver parameters on the quantum bit error rate (QBER) performance of underwater quantum key distribution. We utilize a Monte Carlo approach to simulate the trajectories of emitted photons transmitting in water from the transmitter towards the receiver. Based on propagation delay results, we first determine a proper value for the bit period to avoid intersymbol interference as a result of possible multiple scattering events. Then, based on the angle of arrival of the received photons, we determine a proper field of view to limit the average number of received background noise. Finally, we determine the optimal value for the single photon avalanche diode gate time in the sense of minimizing the QBER for the selected system parameters and given propagation environment.
