摘要：
The advantage distillation (AD) technology provides an efficient scheme to substantially improve the performance of quantum key distribution (QKD). Generally, inserting an additional AD step into measurement-device-independent QKD (MDI-QKD) can enhance the secret key rate and transmission distance drastically. To further promote the performance of practical MDI-QKD systems, we extend the AD technology into MDI-QKD when considering statistical fluctuations. Simulation results show that the AD method has great superiority in improving the performance of practical MDI-QKD systems.
