Quantum coherence in mutually unbiased bases
Yao-Kun Wang, Li-Zhu Ge, Yuan-Hong Tao
We investigate the norm of coherence of quantum states in mutually unbiased bases. We find that the sum of squared norm of coherence of the mixed state single qubit…
Comment on "Unified view of quantum correlations and quantum coherence"
Yao Yao, Li Ge, Mo Li
We show that contrary to what it is claimed in Phys. Rev. A \textbf{94}, 022329 (2016), in general the local projective measurement that induces maximal coherence loss is \textit{n…
The Geometry of Quantum Coherence for Two Qubit States
Yao-Kun Wang, Lian-He Shao, Yu-Ran Zhang
We plot the geometry of several distance-based quantifiers of coherence for Bell-diagonal states. We find that along with both norm and relative entropy of coherence change…
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…
