“…In perspective it would be interesting to inspect solid-state platforms for micromaser-based QBs, exploiting semiconducting double quantum dot geometry [ 74 ] or superconducting quantum circuits [ 75 ], to compare the performance of our proposed model with that of early experimental proof-of-principle implementations of quantum batteries [ 76 , 77 , 78 , 79 , 80 ].…”

We consider a micromaser model of a quantum battery, where the battery is a single mode of the electromagnetic field in a cavity, charged via repeated interactions with a stream of qubits, all prepared in the same non-equilibrium state, either incoherent or coherent, with the matter–field interaction modeled by the Jaynes–Cummings model. We show that the coherent protocol is superior to the incoherent one, in that an effective pure steady state is achieved for generic values of the model parameters. Finally, we supplement the above collision model with cavity losses, described by a Lindblad master equation. We show that battery performances, in terms of stored energy, charging power, and steady-state purity, are slightly degraded up to moderated dissipation rate. Our results show that micromasers are robust and reliable quantum batteries, thus making them a promising model for experimental implementations.

A quantum battery consisting of an ensemble two-level atom is investigated. The battery is charged simultaneously by a harmonic field and an electrostatic field. The results show that the hybrid charging is superior to the previous case of only harmonic field charging in terms of battery capacity and charging power, regardless of whether the interaction between atoms is considered or not. In addition, the repulsive interaction between atoms will increase the battery capacity and charging power, while the attractive interaction between atoms will reduce the battery capacity and discharge power.

“…As now, a variety of theoretical efforts have been made, including examining how quantum resources affect QB performance [10][11][12][13], presenting models for achieving optimal mechanisms for batteries such as high charging and capacity [14][15][16][17][18], slow erosion [19,20], to discussing the environmental effects on charg-ing and discharging of QBs [21][22][23][24][25][26][27]. Furthermore, several experimental platforms have been studied to realize operational quantum batteries [28][29][30][31][32][33]. In this regard, we can address the use of an organic semiconductor that is composed of two-levels systems connected to a microcavity [28].…”

“…Alternatively, QBs can be represented by semiconductor quantum dots embedded within optical microcavities, where energy is exchanged between the solid-state qubit and light fields during charging and discharging [29]. Superconducting circuits are also another field of experimental research for quantum batteries [30,31]. An example is the transmon qutrit QB, which is composed of a three-level transmon coupled to an external field.…”

We present an analysis of the availability and maximum extractable work of quantum batteries in the presence of charge and/or heat steady-state currents. Quantum batteries are modeled as non-interacting open quantum systems (mesoscopic systems) strongly coupled to two thermal and particle reservoirs within the framework of non-equilibrium Green's function theory in a steady-state regime. We found that the battery can be charged manifestly by a steady-state charge current compared to heat one, especially, in an off-resonant transport regime. It allows us to reliably access the performance of the quantum batteries in the high bias-charging regime.
