Geometric optimization of non-equilibrium adiabatic thermal machines and implementation in a qubit system
Pablo Terren Alonso, Paolo Abiuso, Marti Perarnau-Llobet +1
We adopt a geometric approach to describe the performance of adiabatic quantum machines, operating under slow time-dependent driving and in contact to two or more reservoirs with a…
Fundamental limits in Bayesian thermometry and attainability via adaptive strategies
Mohammad Mehboudi, Mathias R. Jørgensen, Stella Seah +3
We investigate the limits of thermometry using quantum probes at thermal equilibrium within the Bayesian approach. We consider the possibility of engineering interactions between t…
Bayesian quantum thermometry based on thermodynamic length
Mathias R. Jørgensen, Jan Kołodyński, Mohammad Mehboudi +2
In this work, we propose a theory of temperature estimation of quantum systems, which is applicable in the regime of non-negligible prior temperature uncertainty and limited measur…
Optimal nonequilibrium thermometry in Markovian environments
Pavel Sekatski, Martí Perarnau-Llobet
What is the minimum time required to take a temperature? In this paper, we solve this question for a large class of processes where temperature is inferred by measuring a probe (th…
Quantum speed-up in collisional battery charging
Stella Seah, Martí Perarnau-Llobet, Géraldine Haack +2
We present a collision model for the charging of a quantum battery by identical nonequilibrium qubit units. When the units are prepared in a mixture of energy eigenstates, the ener…
Contributions from populations and coherences in non-equilibrium entropy production
Adalberto D. Varizi, Mariana A. Cipolla, Martí Perarnau-Llobet +2
The entropy produced when a quantum system is driven away from equilibrium can be decomposed in two parts, one related with populations and the other with quantum coherences. The l…
