On Realization of Back-Action-Evading Measurements and Quantum Non-Demolition Variables via Linear Systems Engineering

Zhiyuan Dong, Weichao Liang, Guofeng Zhang

We establish a framework for realizing back-action-evading (BAE) measurements and quantum non-demolition (QND) variables in linear quantum systems. The key condition, a purely imag…

Simultaneous estimations of quantum state and detector through multiple quantum processes

Shuixin Xiao, Weichao Liang, Yuanlong Wang +3

The estimation of all the parameters in an unknown quantum state or measurement device, commonly known as quantum state tomography (QST) and quantum detector tomography (QDT), is c…
