| 摘 要： | 基于"随机局域操作和经典通讯"对2×5×5纯态量子系统的完全纠缠态进行了分类,共得到34个不等价类.其中有3个类对应的纠缠态含有连续参数.对含参数类的参数进行了详细研究,发现其中有2个类只含1个独立参数;另外1个含有2个独立参数.而且这些独立参数并不完全任意,它们有确定的对称性.对于1个独立参数情形,得到该参数具有D3群对称性.

| Abstract: | We fully classify the quantum pure state of 2×5×5 system under stochastic local operations and classical communication. We find all together 34 inequivalent classes, 3 of which have non-local parameters. One of them has two non-local parameters, and the other two have only one. The parameters are not completely arbitrary. We find that the parameters have some symmetry properties, and there is a D3 symmetry for the case of one parameter. |
