Abstract :
The aim of this paper is explicit calculation of the classical capacity of quantum Gaussian channels, in particular, of those using squeezed states. The calculation is based on a general formula for the entropy of quantum Gaussian state, which is of independent interest, and on the recently proved coding theorem for quantum communication channels
