Abstract
A quantum key generation system intended to mitigate the effect of the dead time of the photon detectors, the system including a photon generator, a photon pathway, a channel switch, and a photon detector unit. The photon pathway optically couples the photon generator and the channel switch. The channel switch is disposed between and optically coupled to the photon pathway and the photon detector unit. The photon detector unit includes a plurality of photon detectors and a plurality of detector unit sub-channels. Each detector unit sub-channel of the plurality of detector unit sub-channels optically couples the channel switch with an individual photon detector of the plurality of photon detectors. The channel switch is actuatable between a plurality of optical engagement positions. Further, each optical engagement position of the channel switch optically couples the photon pathway with a photon detector of the plurality of photon detectors. A plurality of quantum memories may be respectively placed between the switch and the plurality of photon detectors.
