Abstract
The aim of this paper is to give explicit calculation of the classical capa city of quantum Gaussian channels, in particular, involving squeezed states . The calculation is based on a general formula for the entropy of a quantu m Gaussian state, which is of independent interest, and on the recently pro ved coding theorem for quantum communication channels, [S1050-2947(99)00802 -1].
