enhanced measurement device independent quantum key distribution in reference frame independent scenario
Journal of The Optical Society of America B-optical Physics, 2019Co-Authors: Hao Zhang, Chun-mei Zhang, Chunhui Zhang, Guangcan Guo, Qin WangAbstract:The protocol of reference-frame-independent measurement-device-independent quantum key distribution has many advantages compared with other existing quantum key distribution protocols, and thus has many interesting applications in the field of quantum information. In this paper, we propose a scheme on the reference-frame-independent measurement-device-independent quantum key distribution by implementing heralded single-photon sources, where we only need to modulate pump light into two intensities (vacuum and nonvacuum). Through numerical simulations, we demonstrate that our scheme can exhibit much longer transmission distance than the standard three-intensity decoy-state measurement-device-independent quantum key distribution under a reference-frame-independent scenario.

efficient implementation of the decoy state measurement device independent quantum key distribution with heralded single photon sources
Physical Review A, 2013Co-Authors: Qin Wang, Xiang-bin WangAbstract:We study the decoy-state measurement-device-independent quantum key distribution using heralded single-photon sources. This has the advantage that the observed error rate in X basis is in higher order and not so large. We calculate the key rate and transmission distance for two cases: one using only triggered events, and the other using both triggered and non-triggered events. We compare the key rates of various protocols and find that our new scheme using triggered and non-triggered events can give higher key rate and longer secure distance. Moreover, we also show the different behavior of our scheme when using different heralded single-photon sources, i.e., in poisson or thermal distribution. We demonstrate that the former can generate a relatively higher secure key rate than the latter, and can thus work more efficiently in practical quantum key distributions.
