Measurement-device-independent quantum key distribution with source state errors and statistical fluctuation
Cong Jiang, Zong‐Wen Yu, Xiang‐Bin Wang · Physical Review A · 2017
We show how to calculate the secure final key rate in the four-intensity decoy-state measurement-device-independent quantum key distribution protocol with both source errors and statistical fluctuations with a certain failure probability. Our results rely only on the range of only a few parameters in the source state. All imperfections in this protocol have been taken into consideration without assuming any specific error patterns of the source.
