    "abstract": "We present a theoretical study of multi-mode scattering of light by optically\nrandom media, using the Mueller-Stokes formalism which permits to encode all\nthe polarization properties of the scattering medium in a real $4 \\times 4$\nmatrix. From this matrix two relevant parameters can be extracted: the\ndepolarizing power $D_M$ and the polarization entropy $E_M$ of the scattering\nmedium. By studying the relation between $E_M$ and $D_M$, we find that {\\em\nall} scattering media must satisfy some {\\em universal} constraints. These\nconstraints apply to both classical and quantum scattering processes. The\nresults obtained here may be especially relevant for quantum communication\napplications, where depolarization is synonymous with decoherence.",
