Efficiencies of quantum optical detectors [PDF]
Physical Review A, 2014 We propose a definition for the efficiency that can be universally applied to all classes of quantum optical detectors. This definition is based on the maximum amount of optical loss that a physically plausible device can experience while still replicating the properties of a given detector.
