The precision of parameter estimation for dephasing model under squeezed reservoir
Shao-xiong Wu, Chang-shui Yu
We study the precision of parameter estimation for dephasing model under squeezed environment. We analytically calculate the dephasing factor and obtain the analytic quantum…
The effect of center-of-mass motion on photon statistics
Yang Zhang, Jun Zhang, Shao-xiong Wu +1
We analyze the photon statistics of a weakly driven cavity quantum electrodynamics system and discuss the effects of photon blockade and photon-induced tunneling by effectively uti…
The initial-state dependence of quantum speed limit
Shao-xiong Wu, Yang Zhang, Chang-shui Yu +1
The generic bound of quantum speed limit time (the minimal evolution time) for a qubit system interacting with structural environment is investigated. We define a new bound for the…
Effects of the reservoir squeezing on the precision of parameter estimation
Shao-xiong Wu, Chang-shui Yu, He-shan Song
The effects of reservoir squeezing on the precision of parameter estimation are investigated analytically based on non-perturbation procedures. The exact analytic quantum Fisher in…
