最小最优广义量子测量

Minimal optimal generalized quantum measurements

J. I. Latorre, P. Pascual, R. Tarrach

摘要:

最近提出了关于有限个$N$的相同准备系统的最优和有限正算子值测量。考虑到物理实现,我们在这里提出了二能级系统的最佳和最小广义量子测量。我们显式地构造它们直到N=7,并验证它们在N=5时是最小的。最后,我们提出了一个表达式,给出了任意$N$的最小最优测量的大小。

英文摘要:

Optimal and finite positive operator valued measurements on a finite number $N$ of identically prepared systems have been presented recently. With physical realization in mind we propose here optimal and minimal generalized quantum measurements for two-level systems. We explicitly construct them up to N=7 and verify that they are minimal up to N=5. We finally propose an expression which gives the size of the minimal optimal measurements for arbitrary $N$.
