Ergotropy from energetic coherence and the third law of thermodynamics
O. S. Yáñez-Soria, G. Guarnieri, B. Çakmak +1
We study the ergotropy and the thermodynamic potentials of a qubit battery charged by repeated interactions with clusters of thermal ancillas, qubits or oscillators, through a comp…
Shake before use: universal enhancement of quantum thermometry by unitary driving
Emanuele Tumbiolo, Lorenzo Maccone, Chiara Macchiavello +2
Quantum thermometry aims at determining temperature with ultimate precision in the quantum regime. Standard equilibrium approaches, limited by the Quantum Fisher Information given…
Noise-Induced Equalization in quantum learning models
Francesco Scala, Giacomo Guarnieri, Aurelien Lucchi
Quantum noise is known to strongly affect quantum computation, thus potentially limiting the performance of currently available quantum processing units. Even learning models based…
Roadmap on Quantum Thermodynamics
Steve Campbell, Irene D'Amico, Mario A. Ciampini +66
The last two decades has seen quantum thermodynamics become a well established field of research in its own right. In that time, it has demonstrated a remarkably broad applicabilit…
Non-equilibrium thermodynamics of precision through a quantum-centric computation
Mario Motta, Antonio Mezzacapo, Giacomo Guarnieri
Thermodynamic uncertainty relations (TURs) are a set of inequalities expressing a fundamental trade-off between precision and dissipation in non-equilibrium classical and quantum t…
Generalised linear response theory for the full quantum work statistics
Giacomo Guarnieri, Jens Eisert, Harry J. D. Miller
We consider a quantum system driven out of equilibrium via a small Hamiltonian perturbation. Building on the paradigmatic framework of linear response theory (LRT), we derive an ex…

O. Onishchenko, G. Guarnieri, P. Rosillo-Rodes +6
Quantum thermodynamics is aimed at grasping thermodynamic laws as they apply to thermal machines operating in the deep quantum regime, a regime in which coherences and entanglement…
Periodically refreshed quantum thermal machines
Archak Purkayastha, Giacomo Guarnieri, Steve Campbell +2
We introduce unique class of cyclic quantum thermal machines (QTMs) which can maximize their performance at the finite value of cycle duration where they are most irreversible.…
Hyperaccurate thermoelectric currents
André, M. Timpanaro, Giacomo Guarnieri +1
Thermodynamic currents can fluctuate significantly at the nanoscale. But some currents fluctuate less than others. Hyperaccurate currents are those which fluctuate the least, in th…
Quantum thermoelectric transmission functions with minimal current fluctuations
Andre M. Timpanaro, Giacomo Guarnieri, Gabriel T. Landi
Thermodynamic uncertainty relations (TURs) represent a benchmark result in nonequilibrium physics that allows to place fundamental lower bounds on the noise-to-signal ratio (precis…
Time periodicity from randomness in quantum systems
Giacomo Guarnieri, Mark T. Mitchison, Archak Purkayastha +3
Many complex systems can spontaneously oscillate under non-periodic forcing. Such self-oscillators are commonplace in biological and technological assemblies where temporal periodi…

Archak Purkayastha, Giacomo Guarnieri, Steve Campbell +2
Obtaining dynamics of an interacting quantum many-body system connected to multiple baths initially at different, finite, temperatures and chemical potentials is a challenging prob…
Joint statistics of work and entropy production along quantum trajectories
Harry J. D. Miller, M. Hamed Mohammady, Martí Perarnau-Llobet +1
In thermodynamics, entropy production and work quantify irreversibility and the consumption of useful energy, respectively, when a system is driven out of equilibrium. For quantum…

Eoin O'Connor, Giacomo Guarnieri, Steve Campbell
We introduce action quantum speed limits (QSLs) as a family of bounds on the minimal time to connect two states that, unlike the usual geometric approach, crucially depend on how t…
