Protecting quantum Fisher information in correlated quantum channels
Ming-Liang Hu, Hui-Fang Wang
Quantum Fisher information (QFI) has potential applications in quantum metrology tasks. We investigate QFI when the consecutive actions of a quantum channel on the sequence of qubi…

Steered quantum coherence as a signature of quantum phase transitions in spin chains
Ming-Liang Hu, Yun-Yue Gao, Heng Fan
We propose to use the steered quantum coherence (SQC) as a signature of quantum phase transitions (QPTs). By considering various spin chain models, including the transverse-field I…
