迭加态与压缩效应增强

ENHANCEMENT OF SQUEEZING AND SUPERPOSITION STATES

本文运用量子力学态迭加原理,讨论由真空态和压缩态的迭加态获取更深压缩光场的可能性。结果表明,对弱场强浅压缩光场压缩加强效应非常显著;并且在迭加态中还呈现出反聚束的非经典效应。

A way is presented with which the optical field states exhibiting much deeper squeezing can be achieved through a simple superposition of the vacuum and the squeezed states with smaller squeezing. The enhancement effect of squeezing and the antibunching effect exhibiting in the superposition states depend on the average photon number of the squeezed states and, are very remarkable for the field exhibiting much smaller squeezing.
