Experimental Optomechanics

我们的研究目标是实现光驱动的超灵敏微机械传感器。为此，我们制造了精巧的“微型蹦床”，表现出创纪录的力感度和与光学的兼容性，这样，由额外的-通常的少量光施加的力——在单个光子的水平上——将深刻地影响它们的运动。此外，通过部分悬浮这样的系统，我们可以通过用光代替柔性材料来提高灵敏度。最后，我们追求一个定性的新系统，其中光*控制振荡质量的空间分布。这些努力将使我们能够研究宏观量子运动，在量子比特和光之间穿梭量子信息，并探测齐牛顿力。

Our research aims to realize ultrasensitive micromechanical sensors actuated by light. *To this end, we fabricate delicate "micro-trampolines" exhibiting record force sen-*sitivity and compatibility with optics such that the forces exerted by an extra-*ordinarily small quantity of light -- at the level of a single photon -- will *profoundly influence their motion. Additionally, by partially levitating such *systems, we can enhance this sensitivity by essentially replacing flexible *materials with light. Finally, we pursue a qualitatively new system in which light *controls the spatial distribution of oscillating mass. These efforts will enable us *to study macroscopic quantum motion, shuttle quantum information between qubits and *light, and detect zeptonewton forces.
