In this paper, we present a method for measuring arbitrary-order correlation functions of the
light field using a two-level atomic system. Theoretically, light field information should be …

A method to measure the correlation function of a biphoton field, which does not require
single-photon detectors and photocount coincidence schemes, has been proposed and …

We extend the absolute quantum efficiency (QE) calibration method, previously used only for
photon counters, to analog detectors with a high dispersion of single-photon responses. Our …
