摘要：

We introduce a quantum channel describing. photon losses depending oil the degree of polarization mixedness. I I his can he regarded as a model of quantum channel with correlated errors between discrete and continuous degrees of freedom. We consider classical information over a continuous alphabet encoded on weak coherent states as well as classical inforamtion over a discrete alphabet encoded oil single photons using dual rail representation. In both cases we study the one-shot capacity of the channel and its behaviour in terms of correlation between losses and polarization mixedness.
