纳米和微机械固态量子器件已成为人们关注的焦点。可靠地生成其运动的非经典态对于解决有关宏观量子现象的基本问题以及开发传感和转导领域的量子技术都很有意义。我们使用量子光学控制技术有条件地生成纳米机械谐振器的单声子福克态。我们进行了汉伯里·布朗和特维斯型实验，验证了声子态的非经典性质，而无需完全状态重建。我们的结果在单声子水平上建立了机械振荡器的纯光学量子控制。
Nano- and micromechanical solid-state quantum devices have become a focus of attention. Reliably generating nonclassical states of their motion is of interest both for addressing fundamental questions about macroscopic quantum phenomena and for developing quantum technologies in the domains of sensing and transduction. We used quantum optical control techniques to conditionally generate single-phonon Fock states of a nanomechanical resonator. We performed a Hanbury Brown and Twiss-type experiment that verified the nonclassical nature of the phonon state without requiring full state reconstruction. Our result establishes purely optical quantum control of a mechanical oscillator at the single-phonon level.
