N2 - We study an old problem concerning the resolution of the question of whether the supremum of the Holevo upper bound for the output of a quantum channel coincides with the classical capacity of this channel. It is shown that this property takes place for one special case. The additivity of minimal output entropy is proved for the Weyl channel obtained by the deformation of a q-c Weyl channel. The classical capacity of channel is calculated.

AB - We study an old problem concerning the resolution of the question of whether the supremum of the Holevo upper bound for the output of a quantum channel coincides with the classical capacity of this channel. It is shown that this property takes place for one special case. The additivity of minimal output entropy is proved for the Weyl channel obtained by the deformation of a q-c Weyl channel.
