Enhanced Quantum Metrology via Saddle-Point Scrambling in Phase Space
Lei Shao, Hai-Jun Xing, Libin Fu
Nonlinear effects are widely utilized in quantum metrology to enhance measurement precision by leveraging complex dynamical behaviors. Here, we propose a quantum scrambling-integra…
Quantum state preparation and transfer based on the bound state in the doublon continuum
Xiaojun Zhang, Xiang Guo, Yan Zhang +3
Bound states in the continuum (BICs) have attracted intense interest, yet their many-particle counterparts remain largely unexplored in waveguide quantum electrodynamics. We identi…
Two-parameter estimation with three-mode NOON state in a symmetric three-well system
Fei Yao, Yi-Mu Du, Haijun Xing +1
We propose a scheme to realize two-parameter estimation via a Bose-Einstein condensates confined in a symmetric triple-well potential. The three-mode NOON state is prepared adiabat…
Measure of quantum Fisher information flow in multi-parameter scenario
Haijun Xing, Libin Fu
We generalize the quantum Fisher information flow proposed by Lu \textit{et al}. [Phys. Rev. A \textbf{82}, 042103 (2010)] to the multi-parameter scenario from the information geom…
Measure of the density of quantum states in information geometry and its application in the quantum multi-parameter estimation
Haijun Xing, Libin Fu
Recently, there is a growing interest in study quantum mechanics from the information geometry perspective, where a quantum state is depicted with a point in the projective Hilbert…
Parity-Enhanced Quantum Optimal Measurements
Haijun Xing, Libin Fu, Su Yi
We find a large class of pure and mixed input states with which the phase estimation precision saturates the Cramer-Rao bound under the compound measurements of parity and particle…
