Coherent Driving\nof a Single Nitrogen Vacancy Center\nby a Resonant Magnetic Tunnel Junction

Nitrogen vacancy (NV) centers, atomic spin defects in\ndiamond,\nrepresent an active contender for advancing transformative quantum\ninformation science (QIS) and innovations. One of the major challenges\nfor designing NV-based hybrid systems for QIS applications results\nfrom the difficulty of realizing local control of individual NV spin\nqubits in a scalable and energy-efficient way. To address this bottleneck,\nwe introduce magnetic tunnel junction (MTJ) devices to establish coherent\ndriving of an NV center by a resonant MTJ with voltage controlled\nmagnetic anisotropy. We show that the oscillating magnetic stray field\nproduced by a resonant micromagnet can be utilized to effectively\nmodify and drive NV spin rotations when the NV frequency matches the\ncorresponding resonance conditions of the MTJ. Our results present\na new pathway to achieve all-electric control of an NV spin qubit\nwith reduced power consumption and improved solid-state scalability\nfor implementing cutting-edge QIS technological applications.
