一类正原子映射

A class of positive atomic maps

Dariusz Chruscinski, Andrzej Kossakowski

摘要:

在d × d复矩阵代数中构造了一类新的正不可分解映射.这些地图的特点是“最弱”的积极性的财产,因此,他们被称为原子。这类实验为研究量子纠缠提供了一个新的工具。事实证明,它们能够检测到具有“最弱”量子纠缠的状态。

英文摘要:

We construct a new class of positive indecomposable maps in the algebra of `d x d' complex matrices. These maps are characterized by the `weakest' positivity property and for this reason they are called atomic. This class provides a new reach family of atomic entanglement witnesses which define important tool for investigating quantum entanglement. It turns out that they are able to detect states with the `weakest' quantum entanglement.
