The energy level crossing behavior and quantum Fisher information in a quantum well with spin-orbit coupling
Z. H. Wang, Q. Zheng, Xiaoguang Wang +1
We study the energy level crossing behavior in two-dimensional quantum well with the Rashba and Dresselhaus spin-orbit couplings (SOCs). By mapping the SOC Hamiltonian onto an anis…

Enhancing parameter precision of optimal quantum estimation by direct quantum feedback
Qiang Zheng, Li Ge, Yao Yao +1
Various schemes have been proposed to overcome the drawback of the decoherence on quantum-enhanced parameter estimation. Here we suggest an alternative method, quantum feedback, to…
