We propose and analyze a setup to achieve strong coupling between a single trapped atom and a mechanical oscillator. The interaction between the motion of the atom and the mechanical oscillator is mediated by a quantized light field in a laser driven high-finesse cavity. In particular, we show that high fidelity transfer of quantum states between the atom and the mechanical oscillator is in reach for existing or near future experimental parameters. Our setup provides the basic toolbox from atomic physics for coherent manipulation, preparation, and measurement of micromechanical and nanomechanical oscillators.
我们提出并分析了一种实现单个俘获原子与机械振子之间强耦合的装置。原子运动与机械振子之间的相互作用由激光驱动的高精细度腔中的量子化光场介导。特别地，我们表明，对于现有的或在不久的将来的实验参数，原子与机械振子之间量子态的高保真度转移是可以实现的。我们的装置提供了原子物理学中的基本工具箱，用于对微机械和纳米机械振子进行相干操纵、制备和测量。
