    "abstract": "Contrary to the usual assumption that the experimental preparation of pure\nentangled states can be described by mixed states due to white noise, a more\nrealistic description for polarization-entangled states produced by parametric\ndown-conversion is that they are mixed states due to decoherence in a preferred\npolarization basis. This distinction between white and colored noise is crucial\nwhen we look for maximal violations of Bell\u0027s inequalities for two-qubit and\ntwo-qutrit entangled states. We find that violations of Bell\u0027s inequalities\nwith realistic noise for polarization-entangled photons are extremely robust\nfor colored noise, whereas this is not the case for white noise. In addition,\nwe study the difference between white and colored noise for maximal violations\nof Bell\u0027s inequalities for three and four-qubit entangled states.",
