Enhanced weak force sensing based on atom-based coherent quantum noise cancellation in a hybrid cavity optomechanical system
We theoretically investigate the weak force-sensing based on coherent quantum noise cancellation (CQNC) scheme in a hybrid cavity optomechanical system containing a trapped ensemble of ultracold atoms and an optical parametric amplifier (OPA). In our proposed system the back action noise can be completely eliminated at all frequencies as well …
