Generation of a coherent electronic spin cluster in diamond

Abstract

An obstacle for spin-based quantum sensors is magnetic noise due to proximal spins. However, such a spin cluster surrounding the sensor can become an asset, if it can be controlled. Here, we polarize and readout a cluster of three nitrogen (N) electron spins coupled to a single nitrogen-vacancy (NV) spin in diamond. We further achieve sub-nm localization of the cluster spins. Finally, we demonstrate coherent spin exchange between the species by simultaneous dressing of the NV and the N states. These results establish the feasibility of environment-assisted sensing and quantum simulations with diamond spins.
