Entangled coherent states in symmetry phase space and their nonclassical effects

摘要: 研究相空间中对称的纠缠相干态,通过引入正交基矢,利用concurrence方法计算了纠缠度,研究了它们的单、双模压缩以及反聚束效应.数值计算表明,相空间中对称的纠缠相干态与非经典效应之间存在着密切的联系.

Abstract: We discuss the entangled coherent states in symmetry phase space by introducing orthogonal basis, calculate their entanglement by means of concurrence, and investigate their squeezing effects of single-mode and two-mode and antibunching effects. The calculations indicate that the entangled coherent state in symmetry phase space is closely related to nonclassical effect.
