摘要

We investigate quantum-squeezing-enhanced weak-force sensing via a nonlinear optomechanical resonator containing a movable mechanical mirror and an optical parametric amplifier (OPA).Herein,we determined that tuning the OPA parameters can considerably suppress quantum noise and substantially enhance force sensitivity,enabling the device to extensively surpass the standard quantum limit.This indicates that under realistic experimental conditions,we can achieve ultrahigh-precision quantum force sensing by harnessing nonlinear optomechanical devices.
