双模最小关联混态的量子统计性质

Quantum Statistical Properties of Minimum Correlation States

研究了双模最小关联混态在不同参数情况下的量子统计性质。发现在一定的参数范围内双模最小关联混态的二阶相干性违反经典的Cauchy-Schwartz不等式,呈现非经典性相关;同时对双模最小关联混态的压缩特性、亚泊松分布等非经典性质进行了分析,通过数值计算得出,每模光子的压缩性及其亚泊松分布均与参数d的取值密切相关。

In this paper we study the quantum statistical properties of minimum correlation states in different coefficients. We find out that the minimum correlation states disobey with the classical Cauchy-Schwartz inequality and exhibit non-classical correlations. We also study the non-classical properties about squeezing and sub-Poissonian statistics of minimum correlation states.
