摘      要：We demonstrate hybrid photoelectric pulse protocols for reading the spin states of nitrogen-vacancy (N−V) centers in diamond, compatible with coherent spin control and performed on shallow nitrogen-implanted electronic grade diamond. The measurements are carried out on spin ensembles from 1000 to just five N−V centers as a first step towards the fabrication of scalable photoelectric quantum chips. Specific microwave protocols are developed that suppress background photocurrent related to ionization of NS0 defects and provide a high contrast and SNR. The technique is demonstrated on Rabi and Ramsey sequences.
