Abstract

While current quantum optomechanical interfaces typically function in the resolved-sideband regime, where precise quantum state swaps are feasible, this project focuses on low-frequency oscillators and leverages interference phenomena in multimode optomechanics to achieve sideband cooling beyond the quantum limit and normal-mode splitting for a unresolved-sideband system.
