    "abstract": "We consider the propagation of polarized photons in optical fibers under the\naction of randomly generated noise. In such situation, the change in time of\nthe photon polarization can be described by a quantum dynamical semigroup. We\nshow that the hierarchy among the decay constants of the polarization density\nmatrix elements as prescribed by complete positivity can be experimentally\nprobed using standard laboratory set-ups.",
