Decoherence of Nuclear Spins in the Proximity of Nitrogen Vacancy Centers in Diamond

Abstract

Nuclear spins in the proximity of electronic spin defects in solids are promising platforms for quantum information processing due to their ability to preserve quantum states for a remarkably long time. Here we report a comprehensive study of the nuclear decoherence processes in the vicinity of the nitrogen-vacancy (NV) center in diamond. We simulate from first principles the change in the dynamics of nuclear spins as a function of distance and state of the NV center and validate our results with experimental data. Our simulations reveal nontrivial oscillations in the Hahn echo signal, pointing to a new sensing modality of dynamical-decoupling spectroscopy, and show how hybridization of the electronic states suppresses the coherence time of strongly coupled nuclear spins. The computational framework developed in our work is general and can be broadly applied to predict the dynamical properties of nuclear spins.
