摘要
由一些双模相干态一般迭加而成的态.一定条件下可存在非经典效应,如双模压缩、柯西—许瓦兹不等式的违反和亚泊松分布.
The generalize superposition states from several two-mode coherent states are studied.The results are shown that under certain conditions the superposition states may exhibit nonclassical effects,such as two- mode squeezing,violation of the Cauchy-Schwartz inequality and sub-Poissonian statistics.
