Knowledge-dependent optimal Gaussian strategies for phase estimation
Ricard Ravell Rodríguez, Simon Morelli
When estimating an unknown phase rotation of a continuous-variable system with homodyne detection, the optimal probe state strongly depends on the value of the estimated parameter.…

Strongly coupled fermionic probe for nonequilibrium thermometry
Ricard Ravell Rodríguez, Mohammad Mehboudi, Michał Horodecki +1
We characterise the measurement sensitivity, quantified by the Quantum Fisher Information (QFI), of a single-fermionic thermometric probe strongly coupled to the sample of interest…
