半局域非最大纠缠态的测量

Measurements of semi-local and non-maximally entangled states

Berry Groisman, Benni Reznik

摘要:

与相对论因果关系的一致性大大缩小了可测量的可观测量的范围。我们认为,通过削弱理想测量的准备作用,许多这些可观的成为可测量的。特别地,我们通过应用纠缠辅助远程操作,证明了$2\times2$维二分系统的所有厄米可观测量都是可测的。

英文摘要:

Consistency with relativistic causality narrows down dramatically the class of measurable observables. We argue that by weakening the preparation role of ideal measurements, many of these observables become measurable. Particularly, we show by applying entanglement assisted remote operations, that all Hermitian observable of a $2\times2$-dimensional bipartite system are measurable.
