Continuity of quantum conditional information
R Alicki, M Fannes · Journal of Physics A Mathematical and General · 2004
We prove continuity of quantum conditional information S (ρ 12 |ρ 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.
