Paper Abstract

Optical multilevel signals for QKD are evaluated in terms of security and key generation rate when they are used with post-selection. Potential receiver architectures are analyzed from a quantum-mechanical point of view and compared regarding these parameters as well as implementation complexity. Based on that, a coherent state QKD system is proposed.
