Abstract: | We introduce a quantum channel describing photon losses depending
on the degree of polarization mixedness. This can be 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 information over a discrete alphabet
encoded on 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. |
