Estimation theory of photon-magnon coupling strength in a driven-dissipative double-cavity-magnon system
Jia-Xin Peng, Baiqiang Zhu, Weiping Zhang +1
Cavity-magnon systems are emerging as a fruitful architecture for the integration of quantum technologies and spintronic technologies, where magnons are coupled to microwave photon…
Dissipative quantum Fisher information for a general Liouvillian parameterized process
Jia-Xin Peng, Baiqiang Zhu, Weiping Zhang +1
The dissipative quantum Fisher information (DQFI) for a dynamic map with a general parameter in an open quantum system is investigated, which can be regarded as an analog of the qu…
The effect of Quantum Statistics on the sensitivity in an SU(1,1) interferometer
Jie Zeng, Yingxing Ding, Mengyao Zhou +5
We theoretically study the effect of quantum statistics of the light field on the quantum enhancement of parameter estimation based on cat state input the SU(1,1) interferometer. T…
Optomechanical preparation of photon number-squeezed states with a pair of thermal reservoirs of opposite temperatures
Baiqiang Zhu, Keye Zhang, Weiping Zhang
Photon number-squeezed states are of significant value in fundamental quantum research and have a wide range of applications in quantum metrology. Most of their preparation mechani…
