Description
We characterize the measurement sensitivity, quantified by the Quantum Fisher Information (QFI), of a thermometric probe of quantum harmonic oscillator (QHO) strongly coupled to the sample of interest, a bosonic bath at temperature T. For non-equilibrium protocols, in which the probe is measured before reaching equilibrium with the sample, new behavior of the measurement sensitivity arising due to non-Markovian dynamics is expected, as in the fermionic case [arXiv:2310:14655]. We investigate whether QFI rate is maximized at a finite interrogation time t* as in the fermionic case.
