Experimental asymmetric Plug-and-Play Measurement-device-independent quantum key distribution

2016 · DSpace@MIT (Massachusetts Institute of Technology)

Measurement-device-independent quantum key distribution (MDI-QKD) is immune to all security loopholes on detection. Previous experiments on MDI-QKD required spatially separated signal lasers and complicated stabilization systems. In this paper, we perform a proof-of-principle experimental demonstration …

Hacking single-photon avalanche detectors in quantum key distribution via pulse illumination

2020 · Optics Express

Quantum key distribution (QKD) has been proved to be information-theoretically secure in theory. Unfortunately, the imperfect devices in practice compromise its security. Thus, to improve the security property of practical QKD systems, a commonly used …
