论文摘要
我们考虑使用阳性 - 截止测量值的两分量量子状态歧视，并表明通过正 - 阳性 - 转移测量的最小错误歧视与纠缠见证人密切相关。通过使用可分解的纠缠见证人的概念，我们建立了通过积极 - 转移测量的最小歧视歧视条件。我们还提供了所有可能的正聚合物测量值的最大成功概率的上限条件。最后，我们使用多维两分量子状态的示例来说明我们的结果。
We consider bipartite quantum state discrimination using positive-partial-transpose measurements and show that minimum-error discrimination by positive-partial-transpose measurements is closely related to entanglement witness. By using the concept of decomposable entanglement witness, we establish conditions on minimum-error discrimination by positive-partial-transpose measurements. We also provide conditions on the upper bound of the maximum success probability over all possible positive-partial-transpose measurements. Finally, we illustrate our results using examples of multidimensional bipartite quantum states.
