Bell’s inequalities with realistic noise for polarization-entangled photons
Bell’s inequalities with realistic noise for polarization-entangled photons
Contrary to the usual assumption that the experimental preparation of pure entangled states can be described by mixed states due to white noise, a more realistic description for polarization-entangled states produced by parametric down-conversion is that they are mixed states due to decoherence in a preferred polarization basis. This distinction …
