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 of spin-dependent optical transitions; C3 coherent spin control; C4 active photon routing; C5 scalable manufacturability; and C6 low on-chip power dissipation for cryogenic operations. Here, we introduce an architecture that simultaneously achieves C1-C6. We realize piezoelectric strain control of diamond waveguide-coupled tin vacancy centers with ultralow power dissipation necessary. The DC response of our device allows emitter transition tuning by over 20 GHz, combined with low-power AC control. We show acoustic spin resonance of integrated tin vacancy spins and estimate single-phonon coupling rates over 1 kHz in the resolved sideband regime. Combined with high-speed optical routing, our work opens a path to scalable single-qubit control with optically mediated entangling gates.
纳米结构金刚石中的色心有望应用于光量子技术。扩展到实际应用需要满足以下标准的架构：C1自旋量子比特的单个光学寻址；C2自旋相关光学跃迁的频率调谐；C3相干自旋控制；C4有源光子路由；C5可扩展的可制造性；以及C6低温操作时的低片上功耗。在此，我们介绍一种同时实现C1 - C6的架构。我们实现了对金刚石波导耦合锡空位色心的压电应变控制，且所需功耗极低。我们器件的直流响应使发射体跃迁调谐超过20 GHz，并结合了低功耗交流控制。我们展示了集成锡空位自旋的声学自旋共振，并在分辨边带区域估计了超过1 kHz的单声子耦合率。结合高速光路由，我们的工作为通过光介导纠缠门实现可扩展单比特控制开辟了一条道路。
