Redundancy and Synergy of an Entangling Cloner in Continuous-Variable Quantum Communication
We address minimization of information leakage from continuous-variable quantum channels. It is known, that regime of minimum leakage can be accessible for the modulated signal states with variance equivalent to a shot noise, i.e., vacuum fluctuations, in the case of collective attacks. Here we deri...
