Abstract
We consider bistochastic quantum channels generated by unitary representations of the discret group. The proof of the additivity conjecture for the quantum depolarizing channel $\Phi$ based on the decreasing property of the relative entropy is given. We show that the additivity conjecture is true for the channel $\Xi =\Psi \circ \Phi $, where $\Psi $ is the phase damping.
