摘要：

Measurement-device-independent quantum key distribution(MDI-QKD) is proven to be immune to all the detector side channel attacks.With two symmetric quantum channeis,the maximal transmission distance can be doubled when compared with the prepare-and-measure QKD.An interesting question is whether the transmission distance can be extended further.In this work,we consider the contributions of the two-way local operations and classical communications to the key generation rate and transmission distance of the MDI-QKD.Our numerical results show that the secure transmission distances are increased by about 12 km and 8 km when the 1 B and the2 B steps are implemented,respectively.
