  • Abstract
    We derive a general formula of the channel capacity for any (classical-) quantum channel. It can be regarded as a quantum version of Verdu and Han´s result (see IEEE Trans. Inform. Theory, vol.40, p.1147-57, 1994). Our results contain Holevo´s (see IEEE Trans. Inform. Theory, vol.44, p.269-73, 1998) and Schumacher and Westmoreland´s (see Phys. Rev. A, vol.56, p.131-8, 1997) results as the stationary and memoryless case.
