A promising route towards the deterministic creation and annihilation of single-phonons is to couple a single-photon emitter to a mechanical resonator. The challenge lies in reaching the resolved-sideband regime with a large coupling rate and a high mechanical quality factor. We achieve this by coupling self-assembled InAs quantum dots to a small mode-volume phononic-crystal resonator with mechanical frequency Ω/2π = 1.466 GHz and quality factor Q = 2.1 × 10. Thanks to the high coupling rate of g/2π = 2.9 MHz, and by exploiting a matching condition between the effective Rabi and mechanical frequencies, we observe the interaction between the two systems via correlations in the emitted photons. Our results represent a major step towards quantum control of the mechanical resonator via a single-photon emitter.
一种实现单声子确定性产生和湮灭的有前景的途径是将单光子发射器与机械谐振器耦合。挑战在于以大的耦合率和高的机械品质因数达到分辨边带 regime。我们通过将自组装的 InAs 量子点与机械频率Ω/2π = 1.466 GHz 且品质因数 Q = 2.1×10 的小模式体积声子晶体谐振器耦合来实现这一点。得益于 g/2π = 2.9 MHz 的高耦合率，并通过利用有效拉比频率和机械频率之间的匹配条件，我们通过发射光子中的相关性观察到了两个系统之间的相互作用。我们的结果代表了通过单光子发射器对机械谐振器进行量子控制的重要一步。
