Squeezing-enhanced quantum sensing with quadratic optomechanics

Caption

Incorporating intracavity squeezing significantly enhances the performance of quadratic cavity optomechanical sensors. The force sensitivity can reach (10.2 aN)^2/Hz even at room temperature. This advancement opens new opportunities for ultrahigh sensitivity applications in quantum metrology and fundamental physics tests.
