| 摘 要： | 从一般形式上构造了有限维希尔伯特（Ｈｉｌｂｅｒｔ）空间ｑ－畸变谐振子的偶相干态，并讨论了其量子统计特性。发现有限维希尔伯特空间的偶ｑ－相干态与通常无限维空间的偶ｑ－相干态或偶相干态有明显不同的压缩和反聚束特性。前者的偶ｑ－相干态不仅出现正交压缩，而且出现反聚束效应。

| Abstract: | In a general way, even q coherent states in a finite dimensional Hilbert space (FDHS) case are constructed explicitly. Some quantum statistical properties are discussed. It is found that squeezing and antibunching properties of even q coherent states in a FDHS case are different from those of usual even q coherent states. No matter the q deformation exhibits or not, the former all exhibits not only quadrature squeezing but also antibunching effect. |
