Proposed Project
- Squeezed light in a cryogenic opto-mechanical system:
The sensitivity of future interferometric gravitational-wave detectors is now limited by the quantum nature of the light circulating in these instruments. This “standard quantum limit” is also a limit to probe the displacements of cryogenic opto-mechanical systems, which provide a platform for testing different techniques to surpass the standard quantum limit. One promising technique is to use frequency-dependent squeezed light, and ato inject this non-classical light into a system cooled in a dilution fridge to ensire quantum noise is the limiting noise source. The student will remotely work on many aspects (optical simulation, data analysis, FPGA and python programming…) of the experiment.
