论文摘要
现代物理学的一个挑战是研究散装物质对象的量子行为，例如机械振荡器。我们早些时候证明，通过将机械振荡器耦合到嵌入式稀土离子掺杂剂的能级，可以在低声子数量状态下准备这种谐振器。在这里，我们描述了如何扩展此方案以准备动量和位置挤压状态，我们分析了可获得的挤压程度如何取决于初始条件以及振荡器与其热环境的耦合。
A challenge of modern physics is to investigate the quantum behavior of a bulk material object, for instance a mechanical oscillator. We have earlier demonstrated that by coupling a mechanical oscillator to the energy levels of embedded rare-earth ion dopants, it is possible to prepare such a resonator in a low phonon number state. Here, we describe how to extend this protocol in order to prepare momentum- and position squeezed states, and we analyze how the obtainable degree of squeezing depends on the initial conditions and on the coupling of the oscillator to its thermal environment.
