WebMar 10, 2024 · The quantum bounds are obtained by analytical optimization over all possible quantum measurements and estimators that satisfy the given constraints. We obtain hierarchies of increasingly tight bounds that include the quantum Cramér-Rao bound at the lowest order. In the opposite limit, the quantum Barankin bound is the variance of the … WebBarankin bound. We especially remark that more the multiplicative noise is non-circular, less the outliers effect degrades the optimal performance provided by the Barankin bound. 2.
