Entanglement Criteria Based on Quantum Fisher Information
Ao-Xiang Liu, Ma-Cheng Yang, Cong-Feng Qiao
To optimize the entanglement detection, we formulate the metrologically operational entanglement condition in quantum Fisher information by maximizing the QFI on the measurement or…

Quantum Uncertainty Equalities and Inequalities for Unitary Operators
Ao-Xiang Liu, Ma-Cheng Yang, Cong-Feng Qiao
We explore the uncertainty relation for unitary operators in a new way and find two uncertainty equalities for unitary operators, which are minimized by any pure states. Additional…
