Quantum hybrid systems are promising for futuristic quantum technologies [1]. Among others, color centers in diamond, namely nitrogen vacancy centers (NVCs), coupled to their mechanical degrees of freedom [2-4] form such a hybrid device. With robust control of the spin properties of the NVCs and their coupling to the mechanical modes, they can be used for sensing experiments at the nanoscale and also for scalable quantum information processing. In this talk, I will present our recent progress on the design and fabrication of such hybrid devices. To further demonstrate the robustness of the device, we show how the spin readout could be done through mechanical motion and vice versa.
