Abstract

We extend the quantum entropic uncertainty principle beyond measurements, to a pair of finite-dimensional quantum channels acting on the same input system. This also generalizes strong super-additivity inequality by giving a lower bound on generalizations of conditional mutual information. Moreover we show that the corresponding 'squashed' conditional mutual information is additive in this general setting.
