Hybrid photoelectric detection of NV magnetic resonances (PDMR) is
anticipated to lead to scalable quantum chip technology. To achieve this goal,
it is crucial to prove that PDMR readout is compatible with the coherent spin
control. Here we present PDMR MW pulse protocols that filter background
currents related to ionization of NS0 defects and achieve a high contrast and
S/N ratio. We demonstrate Rabi and Ramsey protocols on shallow
nitrogen-implanted electronic grade diamond and the coherent readout of ~ 5 NV
spins, as a first step towards the fabrication of scalable photoelectric
quantum devices
