Multiple-parameter estimation in a sagnac interferometer
Xu Yu, Hongbin Liang, Xiaoguang Wang
We explored the general characteristics of a Sagnac interferometer in a multiparameter estimation process. We find that in the two-parameter estimation scenario, one cannot make bo…

Maximal quantum Fisher information for phase estimation without initial parity
Xu Yu, Xiang Zhao, Luyi Shen +3
Mach-Zehnder interferometer is a common device in quantum phase estimation and the photon losses in it are an important issue for achieving a high phase accuracy. Here we thoroughl…
