Experimental realization of Wheeler's delayed-choice experiment with dual selections
Xiaowan Yang, Xinglei Yu, Liangsheng Li +5
Wheeler's delayed-choice experiment demonstrates wave-particle duality of particles using different experimental configurations of a Mach-Zehnder interferometer. In a quantum versi…
Experimentally realized local-global tradeoff in quantum resources
Yue Dai, Zhiyu Wang, Xinzhi Zhao +2
The interconversion among different quantum resources has attracted considerable attention, exemplified by the tradeoff between coherence and entanglement. However, the relationshi…
Factorization dynamics between quantum Fisher information and quantum coherence
Xinzhi Zhao, Xinglei Yu, Liangsheng Li +2
Quantum Fisher information (QFI) quantifies the sensitivity of a quantum state to a parameter change and plays a key role in quantum metrology. Meanwhile, quantum coherence is a cr…
Towards Robust Optimal Measurements Against Noise in Quantum Metrology
Xinglei Yu, Xinzhi Zhao, Liangsheng Li +4
Quantum parameter estimation utilizes quantum mechanical effects to attain higher measurement precision than classical schemes. In practical implementations, however, noise is inev…
Toward Heisenberg Scaling in Non-Hermitian Metrology at the Quantum Regime
Xinglei Yu, Xinzhi Zhao, Liangsheng Li +4
Non-Hermitian quantum metrology, an emerging field at the intersection of quantum estimation and non-Hermitian physics, holds promise for revolutionizing precision measurement. Her…
Experimental investigation of uncertainty relations for non-Hermitian operators
Xinzhi Zhao, Xinglei Yu, Wenting Zhou +4
Uncertainty relations for Hermitian operators have been confirmed through many experiments. However, previous experiments have only tested the special case of non-Hermitian operato…
Quantum parameter estimation of non-Hermitian systems with optimal measurements
Xinglei Yu, Chengjie Zhang
Quantum parameter estimation with Hermitian systems has been applied in various fields, but there are relatively few results concerning non-Hermitian systems. Here, we study the qu…
