| 摘 要： | 本文研究高斯纯态的高阶压缩与信息熵、结果显示出，高斯纯态的各阶压缩均可同时存在，信息熵相对于相干态的减小对应于压缩的出现，从而首次建立了信息熵与量子起伏之间的关系。

| Abstract: | The higher-order squeezing and information entropy for gaussian puresate are studied in this paper. The results show that the higher-order squeezing can be existed simultaneously and the decrease of information entropy compared with coherent state means appearance of squeezing. The relationbetween the information entropy and quantum fluctuation is first estiblished thereby. |

| Keywords: | gaussian pure state higher-order squeezing information entropy. |
