协变模糊观测量与粗粒化
Covariant fuzzy observables and coarse-graining
摘要：
将模糊可观测量看作是一个清晰可观测量的涂抹，研究了协变模糊可观测量的结构。证明了锐观测量的协变粗粒化就是协变模糊观测量。给出了协变模糊可观测量与相应的锐可观测量信息等价的一个充要条件。
英文摘要：
A fuzzy observable is regarded as a smearing of a sharp observable, and the structure of covariant fuzzy observables is studied. It is shown that the covariant coarse-grainings of sharp observables are exactly the covariant fuzzy observables. A necessary and sufficient condition for a covariant fuzzy observable to be informationally equivalent to the corresponding sharp observable is given.
