Optimal unidirectional amplification induced by optical gain in optomechanical systems
L. N. Song, Qiang Zheng, Xun-Wei Xu +2
We propose a three-mode optomechanical system to realize optical nonreciprocal transmission with unidirectional amplification, where the system consists of two coupled cavities and…

Optomechanically induced nonreciprocity in a three-mode optomechanical system
Xun-Wei Xu, L. N. Song, Qiang Zheng +2
We propose to create optical nonreciprocity in a three-mode optomechanical system comprising one mechanical and two optical modes, where the mechanical mode is coupled with only on…

Enhancing parameter precision of optimal quantum estimation by direct quantum feedback
Qiang Zheng, Li Ge, Yao Yao +1
Various schemes have been proposed to overcome the drawback of the decoherence on quantum-enhanced parameter estimation. Here we suggest an alternative method, quantum feedback, to…
