Noisy Detector? Good! Analysis of Trusted-Receiver Scenario in Continuous-Variable Quantum Key Distribution

In CV-QKD the trusted-receiver assumption allows for a significant improvement in terms of key rate and achievable transmission distance. Moreover, as we demonstrate, sometimes detection noise can even be beneficial for the key rate.

Abstract

In CV-QKD the trusted-receiver assumption allows for a significant improvement in terms of key rate and achievable transmission distance. Moreover, as we demonstrate, sometimes detection noise can even be beneficial for the key rate.
