    "abstract": "Besides many interesting application to the study of foundations of quantum\nmechanics, entangled state are now assuming a large relevance for some\npractical application. In particular, we discuss most recent results obtained\nin our laboratory on the use of two photons entangled states produced in\nparametric down conversion for absolute quantum efficiency calibration of\nphotodetectors, in photon counting regime.",
