Multi-User Continuous-Variable Quantum Key Distribution with Discrete Modulation

Florian Peter Kanitschar (Speaker)

Research output: Poster presentation without proceedings

Abstract

While Quantum Key Distribution is mainly examined in the two-user scenario, modern telecommunication networks consist of multiple nodes. In this poster, we present our recent results, where we try to generalize results for two users to the multi-user case, extending the works of Refs. [1,2,3,4].
