Security of Binary Modulated Continuous Variable Quantum Key Distribution under Collective Attacks

arXiv:0807.3751 · doi:10.1103/PhysRevA.79.012307

Abstract

We give an achievable secret key rate of a binary modulated continuous variable quantum key distribution schemes in the collective attack scenario considering quantum channels that impose arbitrary noise on the exchanged signals. Bob performs homodyne measurements on the received states and the two honest parties employ a reverse reconciliation procedure in the classical post-processing step of the protocol.
