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…
Simultaneous measurement of two non-commuting quantum variables: Solution of a dynamical model
Martí Perarnau-Llobet, Theo M. Nieuwenhuizen
The possibility of performing simultaneous measurements in quantum mechanics is investigated in the context of the Curie-Weiss model for a projective measurement. Concretely, we co…
Autonomous Quantum Refrigerator in a Circuit-QED Architecture Based on a Josephson Junction
Patrick P. Hofer, Martí Perarnau-Llobet, Jonatan Bohr Brask +3
An implementation of a small quantum absorption refrigerator in a circuit QED architecture is proposed. The setup consists of three harmonic oscillators coupled to a Josephson unct…
No-go theorem for the characterisation of work fluctuations in coherent quantum systems
Martí Perarnau-Llobet, Elisa Bäumer, Karen V. Hovhannisyan +2
An open question of fundamental importance in thermodynamics is how to describe the fluctuations of work for quantum coherent processes. In the standard approach, based on a projec…
