	abstract = {The negatively charged nitrogen vacancy center (NV) in\&nbsp;diamond\&nbsp;has generated significant interest as a platform for quantum information processing and sensing in the solid state. For most applications, high quality\&nbsp;optical cavities\&nbsp;are required to enhance the NV zero-phonon line (ZPL) emission. An outstanding challenge in maximizing the degree of NV-cavity coupling is the deterministic placement of NVs within the\&nbsp;cavity.\&nbsp;Here, we report\&nbsp;photonic crystal\&nbsp;nanobeamcavities\&nbsp;coupled to NVs incorporated by a delta-doping technique that allows nanometer-scale vertical positioning of the emitters. We demonstrate\&nbsp;cavities\&nbsp;with Q up to \~{}24 000 and mode volume V \~{} 0.47(λ/n)3\&nbsp;as well as\&nbsp;resonant\&nbsp;enhancement of the ZPL of an NV ensemble with Purcell factor of \~{}20. Our\&nbsp;fabrication\&nbsp;technique provides a first step towards deterministic NV-cavity coupling using spatial control of the emitters.},
