    "abstract": "We calculate the effect of polarization-dependent scattering by disorder on\nthe degree of polarization-entanglement of two beams of radiation. Multi-mode\ndetection converts an initially pure state into a mixed state with respect to\nthe polarization degrees of freedom. The degree of entanglement decays\nexponentially with the number of detected modes if the scattering mixes the\npolarization directions and algebraically if it does not.",
