摘要：

The equivalence relation between lossless beam splitter and nondegenerate parametric amplifier in conditional quantum measurement is derived. Conditioning is performed by measuring the quantum state in one of the two output ports of the device. It is found that the conditional output state of the beam splitter is equal to that of the nondegenerate parametric amplifier under some conditions. Photon counting measurement, heterodyne detection and homodyne detection are considered as the conditional quantum measurement (C) 1997 Elsevier Science B.V.
