Abstract
A method and system for identifying entangled photons includes generating a plurality of sets of four entangled photons, wherein one pair of photons of each set are time correlated, thereby indicating that another pair of four entangled photons are entangled. Quantum metadata comprising a time window corresponding to the generated plurality of sets of four entangled photons is collected. A coincidence of one pair of photons of each of the plurality of the sets of four entangled photons is determined. A state value of at least one photon of the other pair of each of the number of the sets of four entangled photons is determined. Ordered lists of coincidences are compared to ordered lists of state values to determine entangled state information. Time window are compared to times corresponding to the ordered lists. Error conditions are generated if conditions are met.
