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…
Yang-Lee edge singularity and quantum criticality in non-Hermitian PXP model
Wen-Yi Zhang, Meng-Yun Mao, Qing-Min Hu +3
We present a comprehensive theoretical framework for quantum criticality in the non-Hermitian detuned PXP model, and establish the complete phase diagram, which had remained elusiv…
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…
Evolution equation for quantum coherence
Xinzhi Zhao, Jianwei Shao, Yi Zheng +2
Quantum coherence plays an important role in quantum resource theory, which is strongly related with entanglement. Similar to the entanglement evolution equation, we find the coher…
