摘　　要：As a potential candidate for quantum computation and metrology,the nitrogen vacancy(NV)center in diamond presents both challenges and opportunities resulting from charge-state conversion.By utilizing different lasers for the photon-induced charge-state conversion,we achieved subdiffraction charge-state manipulation.The charge-state depletion(CSD)microscopy resolution was improved to 4.1 nm by optimizing the laser pulse sequences.Subsequently,the electron spin-state dynamics of adjacent NV centers were selectively detected via the CSD.The experimental results demonstrated that the CSD can improve the spatial resolution of the measurement of NV centers for nanoscale sensing and quantum information.
