Information Theory

On estimating the output entropy of the tensor product of a phase-damping channel and an arbitrary channel

G. G. Amosov

Steklov Mathematical Institute, Russian Academy of Sciences, Moscow, Russia

Abstract: We obtain a lower estimate for the output entropy of a tensor product of the quantum phase-damping channel and an arbitrary channel. We show that this estimate immediately implies that strong superadditivity of the output entropy holds for this channel as well as for the quantum depolarizing channel.
