Abstract
The present disclosure relates to field of quantum cryptography that discloses method of optimizing performance of Quantum Key Distribution (QKD) protocol. Computing system () extracts one or more coincidence distribution sets generated from one or more timestamps detected during communication by one or more detector pairs associated with sender and receiver of communication. Further, computing system identifies one or more reference lines indicating signal value and noise value in each of one or more coincidence distribution sets. Thereafter, computing system determines time window in one or more coincidence distribution sets by iteratively adjusting one or more reference lines in incremental steps until at least one of, performance parameters, signal value and noise value within time window complies with predefined requirements. Finally, computing system optimizes performance of QKD protocol based on determined time window. present disclosure provides an advantage of optimizing individual Signal-to-Noise Ratio (SNR) while restricting QBER to predefined limit.
