Our experiments leverage low temperature (7K) resonant excitation of NV- to simultaneously read-out the electric field at four nearby NVs [1]. We first exploit NV-NV Coulomb interaction to map out the position of each NVs and then perform repetitive read-out of common stochastic Coulomb fields (spectral diffusion in the bulk). By correlating the electric noise across dimensions and NVs, we identify and localize discrete charge traps in 3D [2].
These results open intriguing opportunities for the microscopic characterization of photo-carrier dynamics and for the manipulation of nanoscale spin-qubit clusters connected via electric fields.
