    "abstract": "We present a novel interferometric technique for performing ellipsometric\nmeasurements. This technique relies on the use of a non-classical optical\nsource, namely, polarization-entangled twin photons generated by spontaneous\nparametric down-conversion from a nonlinear crystal, in conjunction with a\ncoincidence-detection scheme. Ellipsometric measurements acquired with this\nscheme are absolute; i.e., they do not require source and detector calibration.",
