Precision limits for time-dependent quantum metrology under Markovian noise
Luca Previdi, Francesco Albarelli
We derive ultimate precision bounds for estimating parameters encoded in \emph{time-dependent} Hamiltonians in the presence of general Markovian noise, allowing for arbitrary adapt…

OH molecule as a quantum probe to jointly estimate electric and magnetic fields
Luca Previdi, Francesco Albarelli, Matteo G. A. Paris
The hydroxyl radical, hereafter referred to as the OH molecule (OHM), carries both electric and magnetic dipole moments and, as a diatomic molecule, admits a comparatively simple a…

Multi-Parameter Multi-Critical Metrology of the Dicke Model
Luca Previdi, Yilun Xu, Qiongyi He +1
Critical quantum metrology exploits the hypersensitivity of quantum systems near phase transitions to achieve enhanced precision in parameter estimation. While single-parameter est…
