Low-temperature thermometry can be enhanced by strong coupling
Luis A. Correa, Martí Perarnau-Llobet, Karen V. Hovhannisyan +3
We consider the problem of estimating the temperature of a very cold equilibrium sample. The temperature estimates are drawn from measurements performed on a quantum probe st…
Achieving sub-shot-noise sensing at finite temperatures
Mohammad Mehboudi, Luis A. Correa, Anna Sanpera
We investigate sensing of magnetic fields using quantum spin chains at finite temperature and exploit quantum phase crossovers to improve metrological bounds on the estimation of t…
Practical Quantum Metrology in Noisy Environments
Rosanna Nichols, Thomas R. Bromley, Luis A. Correa +1
The problem of estimating an unknown phase using two-level probes in the presence of unital phase-covariant noise and using finite resources is investigated. We introduce a si…
Efficiency of inefficient endoreversible thermal machines
José P. Palao, Luis A. Correa, Gerardo Adesso +1
We present a study of the performance of endoreversible thermal machines optimized with respect to the thermodynamic force associated with the cold bath in the regime of small ther…
Testing a Quantum Heat Pump with a Two-Level Spin
Luis A. Correa, Mohammad Mehboudi
Once in its non-equilibrium steady state, a nanoscale system coupled to several heat baths may be thought-of as a quantum heat pump. Depending on the direction of its stationary he…
