摘要

在本文中，我们研究了基于密度矩阵的相关张量的范数和部分换位的三元系统中的真纠缠。我们首先结合密度矩阵的部分换位，导出了一个检测三重量子位态真纠缠的充分解析准则。然后，我们利用相关张量的范数来研究三重量子态的真纠缠，并通过构造某些矩阵来获得真纠缠准则。通过详细的例子，我们的结果被认为能够检测到比以前的研究更真实的三方纠缠态。

On genuine entanglement for tripartite systems

In this paper, we investigate the genuine entanglement in tripartite systems based on partial transposition and the norm of correlation tensors of the density matrices. We first derive an analytical sufficient criterion to detect genuine entanglement of tripartite qubit states combining with the partial transposition of the density matrices. Then, we use the norm of correlation tensors to study genuine entanglement for tripartite qudit quantum states and obtain a genuine entanglement criterion by constructing certain matrices. With detailed examples, our results are seen to be able to detect more genuine tripartite entangled states than previous studies.
