论文摘要
结果表明，增强的（非线性）重组标准等于基于相关张量的线性标准家族。这些标准概括了原始的（线性）调整标准，并引起了纠缠见证人的家庭。提出了一个适当的限制程序，该程序导致一类新颖的证人与增强的重组标准一样强大。
It is shown that the enhanced (nonlinear) realignment criterion is equivalent to the family of linear criteria based on correlation tensor. These criteria generalize the original (linear) realignment criterium and give rise to the family of entanglement witnesses. An appropriate limiting procedure is proposed which leads to a novel class of witnesses which are as powerful as the enhanced realignment criterion.
