关于三方系统的真纠缠

On genuine entanglement for tripartite systems

Hui Zhao, Lin Liu, Zhi-Xi Wang, Naihuan Jing, Jing Li

摘要:

基于部分转置和密度矩阵的关联张量的范数,研究了三重系统的真纠缠。我们首先结合密度矩阵的部分转置,导出了一个检测三比特量子态纠缠的解析充分判据。然后利用关联张量的范数研究了三重量子量子态的真纠缠,通过构造一定的矩阵得到了一个真纠缠的判据。详细的例子,我们的结果被认为是能够检测到更多的真正的三方纠缠态比以前的研究。

英文摘要:

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 quantum 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.
