摘　　要：在有限维希尔伯特空间中构造了非线性相干态,并研究了该量子态的压缩效应和反聚束效应,给出了压缩效应和反聚束效应与有限维希尔伯特空间维数关系的数值计算结果。Nonlinear coherent states in a finite-dimensional Hilbert space are constructed and some quantum statistical properties are studied. Their squeezing effect and antibunching effect are discussed in detail. The relations between the properties of squeezing and antibunching and the dimensionality of the Hilbert space are shown by making use of numerical calculation.
