英文摘要	The afterpulse effect is an intrinsic characteristic of the single-photon avalanche photodiode that has been widely used in quantum key distribution (QKD). As QKD systems move into the gigahertz regime, the afterpulse effect is no longer ignorable, which will lead to a great deviation compared with the existing analytical model. Here we develop an analytical model to make QKD systems more afterpulse compatible. In addition, we obtain the secure key rate for our model with the analysis of statistical fluctuation using Hoeffding's inequality and Azuma's inequality. Our results show that the optimized parameters of the afterpulse-compatible model can provide a much higher key rate than the optimized parameters of the previous afterpulse-omitted model in the same situation.
