论文摘要
我们提出了纠缠，连贯性，连贯性，转向不平等的行为和任意三量国家的贝尔非局部关系的互补关系。我们表明，存在两个真正纠缠的三质量纯状态的家族具有单个参数，并且它们分别表现出最大的连贯性和转向不平等，分别对固定量的负面性表现出。据发现，对于三季度纯净状态的两部分并发的几何平均值完全等于，尽管对三量混合状态的负态始终小于或等于后者。此外，建立了三方纠缠状态的消极和一阶连贯性之间的互补关系。此外，我们研究了消极和最大转向不平等的密切关系。此外，还获得了针对任意三量状状态的消极和最大贝尔 - 质量违规之间的互补关系。该结果提供了可靠的证据，表明纠缠，连贯性，转向不平等和贝尔非局部之间存在基本联系。
We put forward complementary relations of entanglement, coherence, steering inequality violation, and Bell nonlocality for arbitrary three-qubit states. We show that two families of genuinely entangled three-qubit pure states with single parameter exist, and they exhibit maximum coherence and steering inequality violation for a fixed amount of negativity, respectively. It is found that the negativity is exactly equal to the geometric mean of bipartite concurrences for the three-qubit pure states, although the negativity is always less than or equal to the latter for three-qubit mixed states. Moreover, the complementary relation between negativity and first-order coherence for tripartite entanglement states are established. Furthermore, we investigate the close relation between the negativity and the maximum steering inequality violation. In addition, the complementary relation between negativity and the maximum Bell-inequality violation for arbitrary three-qubit states is obtained. The results provide reliable evidence of fundamental connections among entanglement, coherence, steering inequality violation, and Bell nonlocality.
