Pulsed Photoelectric Coherent Manipulation and Detection of N−V Center Spins in Diamond

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.
