Detecting macroscopic quantum coherence with a cavity optomechanical system
Qiang Zheng, Jianwei Xu, Yao Yao +1
The rigorous resource framework of quantum coherence has been set up recently and excited a wide variety of interests. Here we show that a quantum cavity optomechanical system, as…

Approaching quantum-limited amplification with large gain catalyzed by hybrid nonlinear media in cavity optomechanics
Qiang Zheng, Kai Li, Yong Li
Amplifier is at the heart of almost all experiment carrying out the precise measurement of a weak signal. An idea amplifier should have large gain and minimum added noise simultane…

Invertible condition of quantum Fisher information matrix for a mixed qubit
Ping Yue, Li Ge, Qiang Zheng
Estimating multiparamter simultaneously as precise as possible is an important goal of quantum metrolo- gy. As a first step to this end, here we give a condition determining whethe…
