Work extraction from quantum batteries subject to noisy channels

Quantum Thermodynamics studies the theoretical framework behind the energetic properties of promising quantum devices, such as quantum batteries. It has been shown that quantum batteries may potentially improve charging processes, but it is also crucial to assess the stability of the storage phase if they are in contact with environmental noise.

In this work we formalize the problem of the storage of useful energy in quantum devices in presence of noisy channels. We define new figure of merits to benchmark quantum batteries performance depending on the available resources. We show explicit evaluations for various classes of quantum channels.
