II Quantum Phenomena in Optical Interferometry

摘要: Publisher Summary The quantum analog of classical coherence functions helps to characterize the properties nonclassical radiation. Measurements second-order cannot provide unambiguous evidence light; thus, measurements fourth-order are required distinguish from Interference effects should become weaker as number photons decreases and disappear completely when no more than one photon is in apparatus at a time. wave function system may undergo phase shift (a geometric phase) parameters cyclic change. This change can be observed by interference if cycled compared with another that has not undergone any realized using two spatially separated detectors, or correlating photo detections Interferometry domain characterized complementarity: vs particle, certainty phase, visibility fringes path. paradox undular corpuscular aspects light, which flow description, led many experiments for studying complementarity.
