光场迭加态的压缩效应

The Squeezing Effect of Light Field Superposition State

对迭加态|Ψ>=a|0>+β|n>(n>0)的振幅压缩、振幅平方压缩及高阶压缩效应进行了研究。对于这些迭加态,如果再迭加上一Fock态|m>,同样能存在压缩效应。同时,还发现,振幅各阶压缩与反聚束效应不一定同时出现。

In this paper, the squeezing effect of the amplitude, the square amplitude, and the higher order amplitude are studied in the superposition state |Ψ>=α|0> +β|n>(n>0). If another Fock state |m> superimposes on the superposition state |Ψ>, the existence of the squeezing will not be affecfed. It is also concluded that the various order squeezing of the amplitude and the anti-bunching effect may not exist simultaneously.
