Autonomous Quantum Heat Engine Enabled by Molecular Optomechanics and Hysteresis Switching
Baiqiang Zhu, Pierre Meystre, Weiping Zhang +1
By integrating molecular optomechanics with molecular switches, we propose a scheme for a molecular quantum heat engine that operates autonomously through hysteretic feedback witho…
Atom-light-correlated quantum interferometer with memory-induced phase comb
Wenfeng Huang, Xinyun Liang, Jie Zhao +7
Precise phase measurements by interferometers are crucial in science for detecting subtle changes, such as gravitational waves. However, phase sensitivity is typically limited by t…
Enhanced Quantum Metrology with Non-Phase-Covariant Noise
Jia-Xin Peng, Baiqiang Zhu, Weiping Zhang +1
The detrimental impact of noise on sensing performance in quantum metrology has been widely recognized by researchers in the field. However, there are no explicit fundamental laws…
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…
