Abstract

Building energy storing devices to efficiently deliver energy on demand is currently one of most important goals of the human kind. Quantum Batteries (QB) are promising novel devices, from which one seek to harness quantum features in order to have a better energetic performance if compared to ``classical" batteries. Although several studies on QB emerged in the last decade, there are still challenges to overcome so that one may build realistic QBs. One of this challenges is develop protocols to prevent energy losses in the QB due to the presence of an external environment. The goal of this project is develop a theoretical protocol to encode an QB in a nuclear spin using the Nitrogen-Vacancy Centres in Diamonds platform. This emergent quantum platform is very well controllable and has high coherence lifetime even at room temperature. This make it a suitable system to implement QBs in a solid state system that can work at room temperature.
