论文摘要
我们通过使用密度矩阵的海森贝格 - 韦尔(HW)表示,研究三方和四方量子状态的纠缠和纠缠。基于HW表示中的相关张量,我们提出了检测纠缠和真正的三方和四目标纠缠的标准。详细的示例表明,与以前的标准相比,我们的方法可以检测到更多的纠缠状态。
We study entanglement and genuine entanglement of tripartite and four-partite quantum states by using Heisenberg-Weyl (HW) representation of density matrices. Based on the correlation tensors in HW representation, we present criteria to detect entanglement and genuine tripartite and four-partite entanglement. Detailed examples show that our method can detect more entangled states than previous criteria.
