The negatively charged Nitrogen Vacancy color center (NV) is a spin active defect in diamond with a long spin lifetime at room temperature. We aim to resolve two different NV centres separated by a distance in nanoscopic regime by exploiting Rabi oscillations of the spin of the NV centre which show a spatial dependence due to applied microwave fields. Therefore we fabricate a microwave circuit on the diamond, which will allow us to apply different high intensity microwave fields and gradients. Finally the relation between the Rabi oscillations and the microwave field of two NV centres close to each other can be used in order to compute the distance between them, with a resolution below 50 nm.
