论文摘要
我们的研究采用连接的相关矩阵来量化量子纠缠。矩阵涵盖了评估颗粒之间纠缠程度的所有必要措施。我们从一个三量的状态开始，涉及通过在一个量子上进行部分跟踪来获得混合状态。我们的目标是通过关注连接的相关性来排除非连接部门。这表明连接的相关性对于捕获相关的纠缠度至关重要。该研究对混合状态进行了分类，并观察到可分离状态在每个类别内表现出最低的相关性。我们证明，纠缠量度单调增加了相关度量。这意味着连接的相关性是量子纠缠的有效度量。最后，我们的建议建议从当地角度解释量子纠缠是可能的。可观察到的可被描述为具有当地的向量，但违反了选择自由。
Our study employs a connected correlation matrix to quantify Quantum Entanglement. The matrix encompasses all necessary measures for assessing the degree of entanglement between particles. We begin with a three-qubit state and involve obtaining a mixed state by performing partial tracing over one qubit. Our goal is to exclude the non-connected sector by focusing on the connected correlation. This suggests that the connected correlation is deemed crucial for capturing relevant entanglement degrees. The study classifies mixed states and observes that separable states exhibit the lowest correlation within each class. We demonstrate that the entanglement measure monotonically increases concerning the correlation measure. This implies that connected correlation serves as an effective measure of Quantum Entanglement. Finally, our proposal suggests that interpreting Quantum Entanglement from a local perspective is possible. The observable is described as a vector with locality but violates freedom of choice.
