论文摘要
我们使用密度矩阵的主要基础矩阵表示，研究三方量子系统中的纠缠。使用Schmidt分解和局部统一转换，我们首先将一般状态转换为更简单的形式，然后从简化密度矩阵的相关张量中构造一些特殊矩阵。根据这些矩阵的不同线性组合，提出了必要的条件以检测三方状态的纠缠。详细的示例表明，我们的方法比以前的方法检测到更多的纠缠状态。
We study the entanglement in tripartite quantum systems by using the principal basis matrix representations of density matrices. Using the Schmidt decomposition and local unitary transformation, we first convert the general states to simpler forms and then construct some special matrices from the correlation tensors of the simplified density matrices. Based on the different linear combinations of these matrices, necessary conditions are presented to detect entanglement of tripartite states. Detailed examples show that our method can detect more entangled states than previous ones.
