Recent years have witnessed an explosion of interest in quantum devices for the production,
storage, and transfer of energy. This Colloquium concentrates on the field of quantum …

The seminal work by Sadi Carnot in the early nineteenth century provided the blueprint of a
reversible heat engine and the celebrated second law of thermodynamics eventually …

Quantum technologies are currently the object of high expectations from governments and
private companies, as they hold the promise to shape safer and faster ways to extract …

We investigate the connection between quantum resources and extractable work in
quantum batteries. We demonstrate that quantum coherence in the battery or the battery …

Qubits are physical, a quantum gate thus not only acts on the information carried by the qubit
but also on its energy. What is then the corresponding flow of energy between the qubit and …

Recently, an unconditional advantage has been demonstrated for the process of charging of
a quantum battery in a collisional model [Seah et al., Phys. Rev. Lett. 127, 100601 (2021) …

Stabilizer entropy (SE) quantifies the spread of a state in the basis of Pauli operators. It is a
computationally tractable measure of nonstabilizerness and thus a useful resource for …

The Tavis-Cummings (TC) model, which serves as a natural physical realization of a
quantum battery, comprises N b atoms as battery cells that collectively interact with a shared …

We investigate the coherent energy transfer between two quantum systems mediated by a
quantum bus. In particular, we consider the energy-transfer process between two qubits and …

Quantum batteries are quantum systems that potentially serve as fuel for other quantum
devices by receiving and supplying energy. In this Letter, we investigate the charging …
