Abstract
The researchers propose using detector arrays instead of single detectors to measure quantum photon states in discrete variable QKD systems. A modified BB84 scheme enables qubit transmission below the dead-time threshold, employing an M-dimensional Markov chain model. Their analysis demonstrates novel mathematical expressions for sifted bit rate and secrecy key rate, validated through Monte Carlo simulations. Results indicate a potential M-fold improvement of SBR at high qubit transmission rates.
