[20p-W541-8] Entanglement relaying measurement device independent DPS quantum key distribution

Keywords:quantum key distribution,measurement independent,Quantum entanglement

Measurement device independent (MDI) quantum key distribution (QKD) is being studied, that is free from side-channel attackes utilizing imperfections in photon detectors. We have proposed a MDI-QKD protocole that uses differential-phase shift (DPS) signal. This paper apply the ideal of the MDI DPS scheme to a quantum entanglement relaying system.
