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 …

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

We investigate the charging process of quantum battery (QB) systems in an extended Dicke
model with both atomic interactions and an external driving field. We focus on the effects of …

We consider a collection of two level systems, such as qubits, embedded into a microwave
cavity as a promising candidate for the realization of high power quantum batteries. In this …

We consider a central-spin battery where N b central spins serve as battery cells and N c
bath spins serve as charging units. It is shown that the energy stored in the battery that can …

We present a collision model for the charging of a quantum battery by identical
nonequilibrium qubit units. When the units are prepared in a mixture of energy eigenstates …

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 …

We characterize for the first time the performances of IBM quantum chips as quantum
batteries, specifically addressing the single-qubit Armonk processor. By exploiting the Pulse …
