Direct state reconstruction with coupling-deformed pointer observables
Xuanmin Zhu, Yu-Xiang Zhang, Shengjun Wu
Direct state tomography (DST) using weak measurements has received wide attention. Based on the concept of coupling-deformed pointer observables presented by Zhang \emph{et al}.[Ph…
Ground-state cooling of dispersively coupled optomechanical system in unresolved sideband regime via dissipatively coupled oscillator
Yu-Xiang Zhang, Shengjun Wu, Zeng-Bing Chen +1
In the optomechanical cooling of a dispersively coupled oscillator, it is only possible to reach the oscillator ground state in the resolved sideband regime, where the cavity-mode…
The amplification of weak measurements under quantum noise
Xuanmin Zhu, Yu-Xiang Zhang
The influence of outside quantum noises on the amplification of weak measurements is investigated. Three typical quantum noises are discussed. The maximum values of the pointer's s…
Coupling-Deformed Pointer Observables and Weak Values
Yu-Xiang Zhang, Shengjun Wu, Zeng-Bing Chen
While the novel applications of weak values have recently attracted wide attention, weak measurement, the usual way to extract weak values, suffers from risky approximations and se…
