    "abstract": "We study the quantum properties of the polarization of the light produced in\ntype II spontaneous parametric down-conversion in the framework of a multi-mode\nmodel valid in any gain regime. We show that the the microscopic polarization\nentanglement of photon pairs survives in the high gain regime (multi-photon\nregime), in the form of nonclassical correlation of all the Stokes operators\ndescribing polarization degrees of freedom.",
