在量子纠缠的背景下，我们研究了在局部变换下不增加的多体态的函数。这些单调幅度的数学表征。然后，它们与共享石板转换的最佳策略相关。更详细的结果，提出了纯态的二分系统。它表明，需要一个以上的措施，同时为了完全量化的非本地资源包含在一个二分纯态，同时研究如何这一事实并不持有所谓的渐近极限。最后，在局部变换下的单调性被认为是纠缠度量的唯一自然要求。
In the context of quantifying entanglement we study those functions of a multipartite state which do not increase under the set of local transformations. A mathematical characterization of these monotone magnitudes is presented. They are then related to optimal strategies of conversion of shared slates. More detailed results are presented for pure states of bipartite systems. It is shown that more than one measure is required simultaneously in order to quantify completely the non-local resources contained in a bipartite pure state, while examining how this fact does not hold in the so-called asymptotic limit. Finally, monotonicity under local transformations is proposed as the only natural requirement for measures of entanglement.
