论文摘要
我们研究三方量子系统中的真正多部分纠缠。通过使用Schmidt分解和局部统一转换，我们将一般状态转换为更简单的形式，并考虑简化密度矩阵的Bloch表示中相关张量的某些矩阵。使用这些特殊矩阵，我们获得了真正的多方纠缠的新标准。详细示例表明，与某些现有标准相比，我们的标准能够检测到更多的三方纠缠和真正的三方纠缠状态。
We study the genuine multipartite entanglement in tripartite quantum systems. By using the Schmidt decomposition and local unitary transformation, we convert the general states to simpler forms and consider certain matrices from correlation tensors in the Bloch representation of the simplified density matrices. Using these special matrices, we obtain new criteria for genuine multipartite entanglement. Detail examples show that our criteria are able to detect more tripartite entangled and genuine tripartite entangled states than some existing criteria.
