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…
Optimal temperature estimation in polariton Bose-Einstein Condensate
Dong Xie
Improving the measurement precision of temperature is very important and challenging, especially in the low temperature range. Based on the existence of invariant subspaces during…
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 thermometry in diffraction-limited systems
Dong Xie, Chunling Xu, An Min Wang
We investigate the ultimate quantum limit of resolving the temperatures of two thermal sources affected by the diffraction. More quantum Fisher information can be obtained with the…
