非线性光学的量子效应

Quantum Effects in Nonlinear Optics

简要地论述单模非经典光场的普适判据,提出两种产生光子数压缩态的途径,以及证明奇、偶相干态实际上是种宏观可识别的量子迭加态(即薛定谔猫)。

Presented in this paper are a general criterion for non-classical radiation fields, and two different ways for generation of photon-number squeezed states. It has been shown that the odd and even coherent states are actually superpositions of macroscopically distinct quantum states (popularly known as Schrodinger cats).
