Discrimination of Ohmic thermal baths by quantum dephasing probes
Alessandro Candeloro, Matteo G. A. Paris
We address the discrimination of structured baths at different temperatures by dephasing quantum probes. We derive the exact reduced dynamics and evaluate the minimum error probabi…

Continuous-time quantum walks in the presence of a quadratic perturbation
Alessandro Candeloro, Luca Razzoli, Simone Cavazzoni +2
We address the properties of continuous-time quantum walks with Hamiltonians of the form , being the Laplacian matrix of the underlying graph and being t…

Quantum probes for universal gravity corrections
Alessandro Candeloro, Cristian Degli Esposti Boschi, Matteo G. A. Paris
We address estimation of the minimum length arising from gravitational theories. In particular, we provide bounds on precision and assess the use of quantum probes to enhance the e…
