Enhancing Quantum Metrology with High-order Fisher Information and Experiments
Xin-Zhu Liu, Jun-Li Jiang, Yan-Han Yang +4
Fisher information plays a central role in statistics and quantum metrology, providing the basis for the celebrated Cramér-Rao bound. In this work, we introduce a new information m…

A new entanglement measure based dual entropy
Xue Yang, Yan-Han Yang, Li-Ming Zhao +1
Quantum entropy is an important measure for describing the uncertainty of a quantum state, more uncertainty in subsystems implies stronger quantum entanglement between subsystems.…
