Optimal control for multi-parameter quantum estimation with time-dependent Hamiltonians
Dong Xie, Chunling Xu
We investigate simultaneous estimation of multi-parameter quantum estimation with time-dependent Hamiltonians. We analytically obtain the maximal quantum Fisher information matrix…

Multi-parameter Quantum Magnetometry with Spin States in coarsened measurement reference
Dong Xie, Chunling Xu
We investigate the simultaneous estimation of the intensity and the orientation of a magnetic field by the multi-parameter quantum Fisher information matrix. A general expression i…

Enhancing precision of damping rate by PT symmetric Hamiltonian
Dong Xie, Chunling Xu
We utilize quantum Fisher information to investigate the damping parameter precision of a dissipative qubit. PT symmetric non-Hermitian Hamiltonian is used to enhance the parameter…
