论文摘要
参数化的纠缠单调,即$ q $ - 汇用,也是一种合理的参数化纠缠措施。通过探索$ q $ concurrence的属性,就积极的部分换位和密度矩阵的重新调整,我们提出了$ q $ concurrence的紧密下限,用于任意$ q \ geqslant 2 $。给出了详细的示例,以表明界限比以前的范围更好。
The parameterized entanglement monotone, the $q$-concurrence, is also a reasonable parameterized entanglement measure. By exploring the properties of the $q$-concurrence with respect to the positive partial transposition and realignment of density matrices, we present tight lower bounds of the $q$-concurrence for arbitrary $q\geqslant 2$. Detailed examples are given to show that the bounds are better than the previous ones.
