Optimality of Gaussian Attacks in Continuous-Variable Quantum Cryptography

Year: 2006

Type: article

Abstract: We analyze the asymptotic security of the family of Gaussian modulated quantum key distribution protocols for continuous-variables systems. We prove that the Gaussian unitary attack is optimal for all the considered bounds on the key rate when the first and second momenta of the canonical variables involved are known by the honest parties.
