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”，表现出记录力的敏感性和与光学的兼容性，使得由非常少量的光（在单个光子的水平上）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，我们追求一个新的系统，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。
