Abstract
The key device in single-photon detectors is the avalanche photodiode. When used in quantum key distribution, a protocol for key distribution with security guaranteed by quantum physics laws, the afterpulsing, false counts caused by electrons trapped in the gain region, limits strongly the maximal transmission rate of the system since we have, after an avalanche have occurred, to turn off the photodiode for a fixed time before enabling the avalanche photodiode to receive another photon. In this paper, aiming to overcome the afterpulsing, three smart strategies for single-photon detection are discussed using analytical and numerical procedures.
