论文摘要
基于相关张量的可分离性标准的检测能力在$ d_1 \ otimes d_2 $的一般性各向同性状态的家族中进行了测试。对于$ d_1 \ neq d_2 $,所有这些标准都比积极的部分换位(PPT)标准弱。有趣的是,我们的分析支持了最近的猜想,即基于对称信息的完全正面运算符评估措施(SIC-POVM)的标准比重新调整标准强。
Detection power of separability criteria based on a correlation tensor is tested within a family of generalized isotropic state in $d_1 \otimes d_2$. For $d_1 \neq d_2$ all these criteria are weaker than positive partial transposition (PPT) criterion. Interestingly, our analysis supports the recent conjecture that a criterion based on symmetrically informationaly complete positive operator-valued measure (SIC-POVMs) is stronger than realignment criterion.
