Аннотация: We study the entropy gain for infinite-dimensional dynamical maps (channels). We show that unlike finite-dimensional case where the minimal entropy gain is always nonpositive, there is a plenty of channels with positive minimal entropy gain. We obtain the new lower bound and compute the minimal entropy gain for a broad class of Bosonic Gaussian channels by proving that the infimum is attained on the Gaussian states.
