摘要
运用数值计算方法研究了有限维希尔伯特空间谐振子奇偶相干态的非经典特性．研究表明，在有限维情景，奇相干态不出现压缩但出现反聚束效应；仍相干态不仅出现压缩，而且出现反聚束效应．随着维数Ｓ减少，奇相干态的振幅分量起伏增大而反聚束效应加强，偶相干态的压缩强度减弱但反聚束效应加强．
The nonclassical properties of odd and even coherent states in a finitedimensional Hilbert spaces (FDHS) case are studied by numerical method. It is found that, no squeezing but antibunching effects exist in odd coherent states; both quadrature squeezing and antibunching effects are exist in even coherent states. With the number of dimension reducing, the quadrature fluctuation is increased and the antibunching effects are Enhanced in odd coherent states; and the squeezing effects are weakened but the antibunching effects are Enhanced in even coherent states.
