量子比特效应的共存

Coexistence of qubit effects

Peter Stano, Daniel Reitzner, Teiko Heinosaari

备注：
A paper with identical title is being published on the arXiv simultaneously by P. Busch and H.-J. Schmidt. These authors solve the same problem independently with a different method. In v2 the proof of the main result has been clarified, and some minor errors have been corrected. In v3 some typos have been corrected and a reference has been added

摘要：

我们描述了所有共存的量子比特效应对。这给出了一个详尽的描述，所有对的事件允许，在原则上，发生在一个单一的量子位测量。的特征由三个不相交的条件，这是很容易检查一个给定的一对效果。已知的特殊情况下，遵循我们的一般特征定理。

英文摘要：

We characterize all coexistent pairs of qubit effects. This gives an exhaustive description of all pairs of events allowed, in principle, to occur in a single qubit measurement. The characterization consists of three disjoint conditions which are easy to check for a given pair of effects. Known special cases are shown to follow from our general characterization theorem.
