Quantum metrology with quantum Wheatstone bridge composed of Bose systems
Dong Xie, Chunling Xu, Xiwei Yao +1
The quantum version of a special classical Wheatstone bridge built with a boundary-driven spin system has recently been proposed. We propose a quantum Wheatstone bridge consisting…
Quantum estimation of Kerr nonlinearity in driven-dissipative systems
Dong Xie, Chunling Xu, An Min Wang
We mainly investigate the quantum measurement of Kerr nonlinearity in the driven-dissipative system. Without the dissipation, the measurement precision of the nonlinearity paramete…
Quantum phases transition revealed by the exceptional point in Hopfield-Bogoliubov matrix
Dong Xie, Chunling Xu, An Min Wang
We use the exceptional point in Hopfield-Bogoliubov matrix to find the phase transition points in the bosonic system. In many previous jobs, the excitation energy vanished at the c…
Quantum Thermometry with a Dissipative Quantum Rabi System
Dong Xie, Chunling Xu, An Min Wang
Dissipative quantum Rabi System, a finite-component system composed of a single two-level atom interacting with an optical cavity field mode, exhibits a quantum phase transition, w…
Quantum metrology in coarsened measurement reference
Dong Xie, Chunling Xu, Anmin Wang
We investigate the role of coarsened measurement reference in quantum metrology. Coarsened measurement reference comes from the coarsened reference time and basis. When the measure…
