The nitrogen vacancy (NV) defect center in diamond has emerged as one of the most promising candidates for future solid state quantum technology. In particular recent progress on the integration of NV centers into photonic hybrid platforms attracted attention [1]. We explore the prospects of such an integrated quantum hybrid platform. The applicability of a robust, fast and deterministic entanglement scheme [2] is evaluated. Using realistic conditions and parameters (cavity quality factors, radiative dephasing and spectral diffusion) we find that significant entanglement can be generated between medium distant NV centers via a shared cavity mode. These studies outline a route towards deterministic quantum information processing on a realistic solid state platform.
