Efficient connection of stationary- and flying qubits posts a formidable challenge, yet is one of the demands for the development of applications like quantum networks, distributed quantum computing and quantum communication. Cavity quantum electrodynamics provides enhanced light-matter interaction, hence serving as an attractive tool for spin-photon interfaces. Here, we present our progress of a hybrid quantum photonic interface which interconnects chip-integrated one-dimensional photonic crystal cavities in silicon nitride with negatively charged silicon vacancy centers (SiV) in nanodiamonds. We elaborate on the unique possibilities of dipole alignment by nanomanipulation [1] and show our results on Purcell broadened optical access to the SiV centers electron spin [2].
