| 摘 要： | 利用海森堡不确定关系和薛定谔-罗伯逊不确定关系推导高阶两粒子多模的分离判据条件.通过比较由两种不确定关系得到纠缠判据条件,发现利用薛定谔-罗伯逊不确定关系进行推导,能得到更强的分离判据条件.

| Abstract: | The separation discrimination conditions of higher-order two-particle multiple mode were derived by using Heisenberg and Schrdinger-Robertson uncertainty relations.After comparing these two uncertainty relations,the entanglement discrimination conditions were obtained.It was found that a stronger separation discrimination condition could be obtained based on the derivation with Schrdinger-Robertson uncertain relation. |
