Universal Sensitivity Bound for Thermal Quantum Dynamic Sensing
Rui Zhang, Yang Yang, Wenkui Ding +1
This work unifies the equilibrium and non-equilibrium frameworks of quantum metrology within the context of many-body systems. We investigate dynamic sensing schemes to derive an u…

Identifying the closeness of eigenstates in quantum many-body systems
Haibin Li, Yang Yang, Pei Wang +1
We propose a new quantity called modulus fidelity to measure the closeness of two quantum pure states. Especially, we use it to investigate the closeness of eigenstates of quantum…

Matrix rearrangement approach for the entangling power with mixed qudit systems
Xiao-Ming Lu, Xiaoguang Wang, Yang Yang +1
We extend the former matrix rearrangement approach of the entangling power to the general cases, without the requirement of the same dimensions of the subsystems. The entangling po…
