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…

Experimental quantification of quantum coherence for a set of quantum states

Tianle Zheng, Liangsheng Li, Wenting Zhou +1

We present a direct experimental verification of quantum coherence for a set of quantum states in a basis-independent manner. We find that the theory of quantum coherence for a set…

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…

Genuine multipartite entanglement verification with convolutional neural networks

Yi-Jun Luo, Xuan Leng, Chengjie Zhang

In recent years, the detection of genuine multipartite entanglement (GME) via machine learning has received scant attention. Here, we employ convolutional neural networks (CNNs), a…
