Author(s): Guang-Zheng Ye, Ye Liu, Wan-Jun Su, Yong Li, and Huaizhi Wu Quantum noises impose limits on both backaction cooling and displacement measurements in macroscopic resonators. Here, we demonstrate that for dissipative optomechanical systems in the deeply unresolved sideband regime, squeezed-vacuum engineering of Fano interference enables broadband, tunable supp… [Phys.
