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…
Experimental Characterization of Quantumness Using the Uncertainty Principle, Coherence, and Nonlocality
Yan-Han Yang, Xin-Zhu Liu, Xing-Zhou Zheng +6
Heisenberg's uncertainty principle, coherence and Bell nonlocality have been individually examined through many experiments. In this Letter, we systematically characterize all of t…
Photonic Energy-Coherence Theorem and Experimental Validations
Yan-Han Yang, Xin-Zhu Liu, Jun-Li Jiang +5
Wave-particle duality, intertwining two inherently contradictory properties of quantum systems, remains one of the most conceptually profound aspects of quantum mechanics. By using…
Experimental verification of quantum battery capacity with an optical platform
Xue Yang, Yan-Han Yang, Xin-Zhu Liu +4
Quantum batteries, consisting of quantum cells, are anticipated to surpass their classical counterparts in performance because of the presence of quantum correlations. Recent theor…
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.…
A new parameterized entanglement monotone
Xue Yang, Ming-Xing Luo, Yan-Han Yang +1
Entanglement concurrence has been widely used for featuring entanglement in quantum experiments. As an entanglement monotone it is related to specific quantum Tsallis entropy. Our…
