压缩态的光子统计特性与其它态的光子统计特性有很大的不同。我们讨论了压缩态的反聚束(g~2(0)<1),聚束(1≤g~2(0)≤2)和目前还未被人们重视的超聚束(g~2(0)>2)的特性。给出g~2(0)随压缩态的相态振幅和压缩参数变化而变化的规律。指出可用Hanbury-Brown Twiss实验装置来探测这个变化规律。 压缩态的超聚束是压缩态非经典特性的本质。
The statistical properties of a photon in a compressed state are quite different from those in other states. We discuss the effects of the anti-bunching (g ~ 2 (0) <1), bunching (1≤g ~ 2 (0) ≤2) and the super-bunching 0)> 2). The law of g ~ 2 (0) changing with the amplitude and compression parameters of the squeezed state is given. It is pointed out that the Hanbury-Brown Twiss experimental device can be used to detect this change rule. The squeezed state of super-bundling is the essence of non-classical properties of compressed states.
