Abstract

An optical source is configured to simultaneously generate a set of four time-correlated photons comprising a first pair of photons and a second pair of photons. An interferometer is configured to receive a photon from the first pair of photons and configured to receive another photon from the first pair of photons. A first and a second detector configured to generate an electrical signal in response to measurements of an output of the interferometer. A third detector is configured to generate an electrical signal in response to measurement of a photon from the second pair of photons. A fourth detector is configured to generate an electrical signal in response to measurement of another photon from the second pair of photons. A processor is configured to determine a coincidence of the generated electrical signals in response to measurements of the second pair of photons, thereby identifying the set of four time-correlated photons and heralding an interferometric measurement from the generated electrical signals of the first and second detectors.
