Experimental verification of a coherence factorization law for quantum states
Yi Zheng, Cheng-Jie Zhang, Zheng-Hao Liu +4
As a quantum resource, quantum coherence plays an important role in modern physics. Many coherence measures and their relations with entanglement have been proposed, and the dynami…

Xiuzhe Luo, Zhiyuan Wei, Yongjian Han +2
Superposition principle of wave function in multi-slit interference experiment has been widely accepted by many quantum mechanics textbooks, however the expression ${ψ_{AB}} = {ψ_A…
Experimental Detection of Entanglement Polytopes via Local Filters
Yuanyuan Zhao, Markus Grassl, Bei Zeng +4
Entanglement polytopes result in finitely many types of entanglement that can be detected by only measuring single-particle spectra. With high probability, however, the local spect…
