Continuity of quantum conditional information

Quantum Physics 2015-06-26 v2

Abstract

We prove continuity of quantum conditional information S(ρ12ρ2)S(\rho^{12}| \rho^2) with respect to the uniform convergence of states and obtain a bound which is independent of the dimension of the second party. This can, e.g., be used to prove the continuity of squashed entanglement.
