(Top row) Maximum uncertainty with optimal estimator with initial uncertainty 0.1. The ratio of QFI and cumulative preparation time at each iteration vs. (a) iteration step, and vs. system size at each step with measurement numbers (b) M = 50, (c) M = 100. (Bottom row) Uncertainty with Bayesian estimator with true parameter 0.9 and initial range [0.8, 1.1]. d Iterative uncertainty at each step. Iterative figure of merit vs. system size at each step with (e) M = 50, (f) M = 100.
