论文摘要
我们提出了一个由最近引入的对称测量类别构建的正面地图家族。这些地图用于定义纠缠证人，其中包括其他流行的方法，具有相互无偏基的基础和互公正的测量。给予不可分解的证人特别利益，可用于检测具有阳性部分转位的量子状态。我们提供了几个示例，以进行不同数量的测量。
We propose a family of positive maps constructed from a recently introduced class of symmetric measurements. These maps are used to define entanglement witnesses, which include other popular approaches with mutually unbiased bases and mutually unbiased measurements. A particular interest is given to indecomposable witnesses that can be used to detect entanglement of quantum states with positive partial transposition. We present several examples for different number of measurements.
