Transition from pure-state to mixed-state entanglement by random scattering

J. L. van Velsen, C. W. J. Beenakker

Published 2004-03-12Version 1

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