Active-feedback quantum control of an integrated low-frequency | ResearchBunny

Abstract

This paper demonstrates measurement-based feedback cooling on a fully integrated optomechanical device operating in the deep sideband-unresolved limit. Achieving a minimal average phonon occupation of 0.76 (pre-cooled with liquid helium) and 3.5 (liquid nitrogen), significant sideband asymmetry verifies the quantum character of the mechanical motion. The method and device are suitable for quantum-limited sensing applications.
