论文摘要
我们研究了本文中任何量子状态的多部分量子纠缠的紧密一夫一妻关系。首先，我们为多阶量子系统获得一类的下限，这些系统改善了先前的结果。接下来，我们通过新不平等的方式在三方量子系统中建立了一类紧密的一夫一妻制关系。此外，我们将这种关系推广到多方量子系统。然后我们证明我们获得的下限大于现有的限制。终于提供了详细的示例。
We investigate tight monogamy relations of multiparty quantum entanglement for any quantum state in this paper. First, we obtain a class of lower bounds for multiparty quantum systems which improve the previous results. Next, we establish a class of tighter monogamy relations in tripartite quantum systems by means of the new inequality. Furthermore, we generalize this relations to multiparty quantum systems. And then we prove the lower bounds we obtained are larger than the existing ones. Detailed examples are provided at last.
