Enhancing teleportation of quantum Fisher information by partial measurements
Xing Xiao, Yao Yao, Wo-Jun Zhong +2
The purport of quantum teleportation is to completely transfer information from one party to another distant partner. However, from the perspective of parameter estimation, it is t…
Quantum coherence in multipartite systems
Yao Yao, Xing Xiao, Li Ge +1
Within the unified framework of exploiting the relative entropy as a distance measure of quantum correlations, we make explicit the hierarchical structure of quantum coherence, qua…
Classical-driving-enhanced parameter-estimation precision of a non-Markovian dissipative two-state system
Yan-Ling Li, Xing Xiao, Yao Yao
The dynamics of quantum Fisher information (QFI) of the phase parameter in a driven two-state system is studied within the framework of non-Markovian dissipative process. The influ…
Implications and applications of the variance-based uncertainty equalities
Yao Yao, Xing Xiao, Xiaoguang Wang +1
In quantum mechanics, the variance-based Heisenberg-type uncertainty relations are a series of mathematical inequalities posing the fundamental limits on the achievable accuracy of…
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…
