Bridging the gap between theory and practice in quantum cryptography

2015 · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE

Quantum key distribution (QKD) needs to close the big gap between theory and practice to be a suitable technology for achieving information-theoretic secure communications. Indeed, recent studies on side-channel attacks have exposed the vulnerabilities of …

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 …
