Continuous variable subcarrier wave quantum key distribution with discrete modulation: mathematical model and finite-key analysis

2019 · arXiv (Cornell University)

In this paper we propose a continuous-variable subcarrier wave quantum key distribution scheme with homodyne detection and present its security analysis in the finite-size regime. We calculate a lower bound on the secret key rate …

Dynamics of field observables in quantum channels

2021 · Journal of Physics Conference Series

Abstract We consider the time evolution of the mean values of the quadrature operators’ observables and the dynamics of the mean photon number variance for an arbitrary quantum state in a single mode transmitted through …
