Security of Quantum Key Distribution with Coherent States and Homodyne Detection
arXiv:quant-ph/0312018 · doi:10.1103/PhysRevLett.93.170502
Abstract
We assess the security of a quantum key distribution protocol relying on the transmission of Gaussian-modulated coherent states and homodyne detection. This protocol is shown to be equivalent to a squeezed state protocol based on a CSS code construction, and is thus provably secure against any eavesdropping strategy. We also briefly show how this protocol can be generalized in order to improve the net key rate.
