We here present the rate analysis and a proof of principle demonstration of a device-independent quantum key distribution protocol requiring the lowest detection efficiency necessary to achieve a secure key compared to device-independent protocols known so far. The protocol is based on a non-maximally entangled state and its experimental demonstration has been performed by two-photon bipartite entangled states. The improvement with respect to protocols involving maximally entangled states has been estimated.

Abstract

We here present the rate analysis and a proof of principle demonstration of a device-independent quantum key distribution protocol requiring the lowest detection efficiency necessary to achieve a secure key compared to device-independent protocols known so far. The protocol is based on a non-maximally entangled state and its experimental demonstration has been performed by two-photon bipartite entangled states. The improvement with respect to protocols involving maximally entangled states has been estimated.
