Description
Summary:Abstract The optomechanical system has developed a significant breakthrough in quantum science, especially since it can further improve the precision and sensitivity of the measurement in the quantum region. Here, we study a feasible optomechanical proposal in a hybrid quantum system, which can ensure a quantum sensor with further enhanced sensitivity. With the joint assistance of microwave modifying and optical parametric amplification, the effective line width of this supermode is further reduced around the critical point, and it can therefore result in a resolvable spectrum to display a much weaker mechanical frequency shift, which is perhaps induced by a tiny mass or charged particles in this system. We also hope there might be some useful applications for this attempt in the area of quantum measurement.
