Abstract
In this article, we apply non-linear modulation techniques to continuous variables quantum key distribution protocols. More specifically, we try to relate the interference of spying the quantum channel to the probability of anomaly defined in non-linear modulation schemes. In this way, the probability of anomaly can be used to quantify the spy’s knowledge of the transmitted information.
