Atom-based coherent quantum-noise cancellation in optomechanics
A design of a quantum force sensor is proposed to achieve coherent quantum noise cancellation (CQNC) by optically coupling a mesoscopic mechanical resonator to an ensemble of ultracold atoms, which has the specific advantage of allowing easy experimental realization of CQNC to reduce quantum noises below the standard quantum limit.
