Electrical control of a single nitrogen-vacancy center by nanoscale engineered magnetic domain wall motions

ORAL

Abstract

Control and readout of qubits form the technical foundation for novel quantum computing and simulation technologies. The nitrogen-vacancy (NV) center, an intrinsic three-level spin system, has received enormous interest on this regard due to its excellent quantum coherence, high fidelity of operations, and versatile functionality over broad experimental conditions. Here, utilizing magnetic multi-layers with spontaneous perpendicular anisotropy, we implemented a hybrid NV-magnetic-domain-wall system, and demonstrated electrical control of the NV spin properties. The mutual interaction between NV spin qubits and magnetic textures calls for further studies to fulfill their promise for next generation quantum spintronic technologies.
