Explicit asymptotic secret key rate of continuous-variable quantum key distribution with an arbitrary modulation
We establish an analytical lower bound on the asymptotic secret key rate of continuous-variable quantum key distribution with an arbitrary modulation of coherent states. Previously, such bounds were only available for protocols with a Gaussian modulation, and numerical bounds existed in the case of...
