Offer Description
Conduct experimental research, analyze data, model, and disclose scientific conclusions.
Optomechanics, the interaction between light and mechanical oscillators, is a burgeoning field at the interface of quantum optics, mesoscopic physics, and mechanical micro/nano systems. Using light, it has recently been possible to control and read-out the quantum states of mesoscopic mechanical resonators. This has been notably achieved with nano-optomechanical disk resonators fabricated in our team, where the simultaneous confinement of light and mechanical motion in a sub-micron volume enables strong optomechanical interaction. The implications of such developments in the field of quantum sensing remain to be explored.
This project aims to bring mechanical scanning probes into the experimental quantum domain using optomechanics. Quantum theory postulates that energy exchanges between physical systems take place with a certain granularity, in quantities that are multiples of an energy quantum. This quantum regime of interactions has never been illustrated by local mechanical measurements, such as those made with an atomic force microscope (AFM). Detecting the exchange of a single quantum of energy between a physical system and mechanical force probe represents the ultimate level of sensitivity allowed by microscopic laws, and is therefore a considerable scientific and technological stake for sensing applications of optomechanics. This project aims at reaching this experimental regime, before addressing the subject of arbitrary quantum state production for optimal sensing.
