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.

我们的研究目标是实现超灵敏的光致微机械传感器。为此，我们制造了精细的“微型蹦床”，它表现出记录力的敏感性和与光学的兼容性，这样，由一个额外的--通常是少量的光--在一个光子的水平上--施加的力将深刻地影响它们的运动。此外，通过部分悬浮这样的系统，我们可以通过基本上用光代替柔性材料来提高这种灵敏度。最后，我们追求一个质的新系统，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，并检测zeptonewton力。
