Measurement device independent quantum key distribution (MDI-QKD) can remove all the side-channel attacks from imperfection in the detection side, since firstly proposed by Lo et al, it shows a great influence in the field of quantum key distribution, it has made great progress in both theory and experiment. However, error source undoubtedly influence its property. In this paper, we analyze the performance of MDI-QKD system with error sources like mode mismatch and background count rate. The simulation shows that the optimization of asymmetric case and the optimal choice of intensity of the signal state may enhance the performance of MDI-QKD system.
Keywords:theoretical physics; quantum communication; measurement device independent quantum key distribution; asymptotic key rate
