论文摘要
我们考虑了一个光机电腔，该腔是由短脉冲驱动的频道驱动。通过适当选择脉冲间距，我们表明，即使存在机械耗散和中等辐射压的相互作用，也可以实现地面冷却和机械挤压。我们提供了频道背面探测测量值的完整量子力学处理，为此我们提供了简单的分析洞察力，并讨论了挤压机械状态的准备和验证。我们进一步考虑了一对与公共腔场连接的非相互作用的机械谐振器的频道驾驶，并表明它们可以同时冷却和纠缠。频道量子光学机械将基于测量的机械系统的量子控制扩展到了高腔极限之外。
We consider an optomechanical cavity that is driven stroboscopically by a train of short pulses. By suitably choosing the inter-pulse spacing we show that ground-state cooling and mechanical squeezing can be achieved, even in the presence of mechanical dissipation and for moderate radiation-pressure interaction. We provide a full quantum-mechanical treatment of stroboscopic backaction-evading measurements, for which we give a simple analytic insight, and discuss preparation and verification of squeezed mechanical states. We further consider stroboscopic driving of a pair of non-interacting mechanical resonators coupled to a common cavity field, and show that they can be simultaneously cooled and entangled. Stroboscopic quantum optomechanics extends measurement-based quantum control of mechanical systems beyond the good-cavity limit.
