Indirect Control of the ${}^{29}\mathrm{Si}{\mathrm{V}}^{-}$ Nuclear Spin in Diamond

Abstract

Coherent control and optical readout of the electron spin of the ${}^{29}$SiV${}^{-}$ center in diamond has been demonstrated in literature, with exciting prospects for implementations as memory nodes and spin qubits. Nuclear spins may be even better suited for many applications in quantum information processing due to their long coherence times. Control of the ${}^{29}$SiV${}^{-}$ nuclear spin using conventional NMR techniques is feasible, albeit at slow kilohertz rates due to the nuclear spin's low gyromagnetic ratio. In this work we theoretically demonstrate how indirect control using the electron spin-orbit effect can be employed for high-speed, megahertz control of the ${}^{29}$Si nuclear spin. We discuss the impact of the nuclear spin precession frequency on gate times and the exciting possibility of all optical nuclear spin control.
