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…
State-Independent Error-Disturbance Tradeoff For Measurement Operators
S. S. Zhou, Shengjun Wu, H. F. Chau
In general, classical measurement statistics of a quantum measurement is disturbed by performing an additional incompatible quantum measurement beforehand. Using this observation,…
Localization in Quantum Walks on a Honeycomb Network
Changyuan Lyu, Luyan Yu, Shengjun Wu
We systematically study the localization effect in discrete-time quantum walks on a honeycomb network and establish the mathematical framework. We focus on the Grover walk first an…
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…
Entangled bases with fixed Schmidt number
Yu Guo, Shuanping Du, Xiulan Li +1
An entangled basis with fixed Schmidt number (EBk) is a set of orthonormal basis states with the same Schmidt number in a product Hilbert space $\mathbb{C}^d\otimes\mathbb{…
