biased reservoirs. Averaging over the measurement outcomes, we derive exact formulas for …

Thermodynamic computing via autonomous quantum thermal machines

P Lipka-Bartosik, M Perarnau-Llobet, N Brunner - Science Advances, 2024 - science.org
We develop a physics-based model for classical computation based on autonomous
quantum thermal machines. These machines consist of few interacting quantum bits (qubits) …

Hyperbolic enhancement of a quantum battery

CA Downing, MS Ukhtary - Physical Review A, 2024 - APS
A quantum system which can store energy, and from which one can extract useful work, is
known as a quantum battery. Such a device raises interesting issues surrounding how …

Quantum computers, quantum computing, and quantum thermodynamics

F Cleri - Frontiers in Quantum Science and Technology, 2024 - frontiersin.org
Quantum thermodynamics aims to extend standard thermodynamics and non-equilibrium
statistical physics to systems with sizes well below the thermodynamic limit. It is a rapidly …

Experimental analysis of energy transfers between a quantum emitter and light fields

I Maillette de Buy Wenniger, SE Thomas, M Maffei… - Physical Review Letters, 2023 - APS
Energy can be transferred between two quantum systems in two forms: unitary energy—that
can be used to drive another system—and correlation energy—that reflects past …
J Xuereb, P Erker, F Meier, MT Mitchison, M Huber - Physical Review Letters, 2023 - APS
In order to unitarily evolve a quantum system, an agent requires knowledge of time, a
parameter that no physical clock can ever perfectly characterize. In this Letter, we study how …

Third law of thermodynamics and the scaling of quantum computers

L Buffoni, S Gherardini, E Zambrini Cruzeiro, Y Omar - Physical Review Letters, 2022 - APS
The third law of thermodynamics, also known as the Nernst unattainability principle, puts a
fundamental bound on how close a system, whether classical or quantum, can be cooled to …
