Color centers (CCs) in nanostructured diamond are promising for optically linked quantum technologies. Scaling to useful applications motivates architectures meeting the following criteria: C1 individual optical addressing of spin qubits; C2 frequency tuning spin-dependent transitions; C3 coherent control; C4 active photon routing; C5 scalable manufacturability; and C6 low on-chip power dissipation cryogenic operations. Here, we introduce an architecture that simultaneously achieves C1–C6. We realize piezoelectric strain control waveguide-coupled tin vacancy with ultralow necessary. The DC response our device allows emitter transition by over 20 GHz, combined low-power AC control. show acoustic resonance integrated spins estimate single-phonon coupling rates 1 kHz resolved sideband regime. Combined high-speed routing, work opens a path single-qubit mediated entangling gates.
