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.

我们的研究旨在实现光驱动的超灵敏微机械传感器。为此，我们制造了精致的“微型蹦床”，表现出创纪录的力敏感性和与光学的兼容性，使得极少量的光（在单个光子的水平​​上）施加的力将深刻地影响他们的动议。此外，通过部分悬浮此类系统，我们可以通过用光代替柔性材料来增强这种灵敏度。最后，我们追求一种全新的系统，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传输量子信息，并检测 zeptonewton 力。
