最佳协变测量:紧对称群和相位可观量的情况

Optimal covariant measurements: the case of a compact symmetry group and phase observables

Claudio Carmeli, Teiko Heinosaari, Juha-Pekka Pellonpää, Alessandro Toigo

摘要:

我们研究了量子观测量的各种最优性准则。观测量表示为协变的正算子值的措施,我们考虑的情况下,当对称群是紧的。作为一个例子,检查相位可观。

英文摘要:

We study various optimality criteria for quantum observables. Observables are represented as covariant positive operator valued measures and we consider the case when the symmetry group is compact. Phase observables are examined as an example.
