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由光引起的超敏感微型传感器。为此，我们制造了精致的“微晶状体”，表现出记录的力量势力和与光学的兼容性，从而使外部少量光（在单个光子的水平​​上）施加的力会严重影响其运动。此外，通过部分悬浮此类系统，我们可以通过基本上用光替换柔性材料来增强这种灵敏度。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，量子和光之间的量子信息，并检测Zeptonewton力量。
