量子光学测量技术为通过腔光学力学对机械振荡器进行量子控制提供了丰富的途径。特别是,一个强大的,但很少探索的组合利用光学测量,以执行预示的非高斯机械状态的准备,然后通过断层扫描,以确定机械相空间分布。在这里,我们实验上进行预示单声子和多声子减法通过光子计数到激光冷却的机械热态与布里渊光学机械系统在室温下,并使用光外差探测测量的参数化的维格纳分布的非高斯的机械状态。这里开发的技术先进的光学为基础的断层扫描的机械状态的最新技术,并将是有用的广泛的应用和基础研究,利用机械量子态工程和断层扫描。
Quantum optical measurement techniques offer a rich avenue for quantum control of mechanical oscillators via cavity optomechanics. In particular, a powerful yet little explored combination utilizes optical measurements to perform heralded non-Gaussian mechanical state preparation followed by tomography to determine the mechanical phase-space distribution. Here, we experimentally perform heralded single-phonon and multiphonon subtraction via photon counting to a laser-cooled mechanical thermal state with a Brillouin optomechanical system at room temperature and use optical heterodyne detection to measure the-parametrized Wigner distribution of the non-Gaussian mechanical states generated. The techniques developed here advance the state of the art for optics-based tomography of mechanical states and will be useful for a broad range of applied and fundamental studies that utilize mechanical quantum-state engineering and tomography.
