Diamond mechanical systems in the quantum regime provide many excite opportunities in quantum sensing, networking, and computing. Diamond combines superb mechanical and thermal properties with highly coherent embedded defect-based qubits, such as the nitrogen vacancy (NV) center and silicon vacancy (SiV) center. Here I present work on a novel hybrid quantum system based on a diamond nanomechanical resonator strain-coupled to embedded spin qubits. I discuss the properties of diamond optomechanical crystals operating near their quantum ground state, and I discuss ongoing efforts to realize meteorologically useful many-body entangled states of embedded spin, where interactions are mediated by the phononic modes.
