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 batteries are devices made from quantum states, which store and release energy
in a fast and efficient manner, thus offering numerous possibilities in future technological …

A search for dark matter axions with masses> 10 μ eV/c 2 has been performed using the
HAYSTAC experiment's squeezed state receiver to achieve subquantum limited noise. This …

Theoretical explorations have revealed that quantum batteries can exploit quantum
correlations to achieve faster charging, thus promising exciting applications in future …

We propose to use a quantum spin chain as a device to store and release energy coherently
and we investigate the interplay between its internal correlations and outside decoherence …

We show that a micromaser is an excellent model of quantum battery. A highly excited, pure,
and effectively steady state of the cavity mode, charged by coherent qubits, can be achieved …

The quantum battery (QB) makes use of quantum effects to store and supply energy, which
may outperform its classical counterpart. However, there are two challenges in this field. One …

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) …

We study a quantum battery made out of N nonmutually interacting qubits coupled to a
dissipative single electromagnetic field mode in a resonator. We quantify the charging …
