Abstract:
The cryptographic resistance of a quantum key distribution protocol with phase-time encoding has been analyzed for the case of a nonstrictly single-photon source and a communication channel with losses. It has been shown that eavesdropper’s information on the key for a long communication channel is determined only by the von Neumann entropy of the source at the receiver side and the critical length of the communication channel is determined primarily by dark counts of photodetectors.
