Reaching the Limits of Ground-State Metrology with Many-Body Probes
Erik L. André, Víctor Izquierdo, Ricard Puig +2
We investigate the physical requirements to reach the ultimate limits of ground-state metrology -- i.e., the estimation of an unknown parameter of an -body Hamiltonian via m…

Parameter Estimation in a Continuously Monitored Non-Markovian Quantum System
Erik L. André, Pharnam Bakhshinezhad, Patrick P. Potts +2
Continuous monitoring is a powerful tool for analyzing quantum systems and is increasingly used as a non-demolition technique in quantum metrology. In this context, noisy data acqu…

Strategy optimization for Bayesian quantum parameter estimation with finite copies: Adaptive greedy, parallel, sequential, and general strategies
Erik L. André, Jessica Bavaresco, Mohammad Mehboudi
In this work, we study Bayesian quantum parameter estimation given a finite number of uses of the process encoding one or more unknown physical quantities. We analyze the performan…
