Controlled quantum machines have matured significantly. A natural next step is to
increasingly grant them autonomy, freeing them from time-dependent external control. For …

We develop a physics-based model for classical computation based on autonomous
quantum thermal machines. These machines consist of few interacting quantum bits (qubits) …

Miniaturization has been the driving force in contemporary technologies. However, two main
obstacles limit further progress: additional reduction in size has reached its quantum limit …

Nonequilibrium effects may have a profound impact on the performance of thermal devices
performing thermodynamic tasks such as refrigeration or heat pum**. The possibility of …

We experimentally demonstrate a recently proposed single-junction quantum-circuit
refrigerator (QCR) as an in situ tunable low-temperature environment for a superconducting …

We demonstrate how to incorporate a catalyst to enhance the performance of a heat engine.
Specifically, we analyze efficiency in one of the simplest engine models, which operates in …

The theory of quantum thermodynamics investigates how the concepts of heat, work, and
temperature can be carried over to the quantum realm, where fluctuations and randomness …

Few-level systems coupled to thermal baths provide useful models for quantum
thermodynamics and to understand the role of heat currents in quantum information settings …

We consider a three-stroke engine in the microscopic regime where the working body of the
engine is composed of a two-level system. The working body of the engine aims to withdraw …

We consider a model of heat engine operating in the microscopic regime: the two-stroke
engine. It produces work and exchanges heat in two discrete strokes that are separated in …
