A two-disk approach to the synthesis of coherent passive equalizers for linear quantum systems
Valery Ugrinovskii, Shuixin Xiao
The coherent equalization problem consists in designing a quantum system acting as a mean-square near-optimal filter for a given quantum communication channel. The paper develops a…

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…
