Certification of non-classicality in all links of a photonic star network without assuming quantum mechanics
Ning-Ning Wang, Alejandro Pozas-Kerstjens, Chao Zhang +6
Networks composed of independent sources of entangled particles that connect distant users are a rapidly developing quantum technology and an increasingly promising test-bed for fu…
Detecting Entanglement by Pure Bosonic Extension
Xuanran Zhu, Chao Zhang, Chenfeng Cao +3
In the realm of quantum information theory, the detection and quantification of quantum entanglement stand as paramount tasks. The relative entropy of entanglement (REE) serves as…
Experimental beating the standard quantum limit under non-markovian dephasing environment
Huan Cao, Chao Zhang, Yun-Feng Huang +4
Entanglement enhanced quantum metrology has been well investigated for beating the standard quantum limit (SQL). However, the metrological advantage of entangled states becomes muc…
Experimental implementation of Hardy-like quantum pigeonhole paradoxes
Shihao Ru, Cen-Xiao Huang, Xiao-Min Hu +7
We present the general Hardy-like quantum pigeonhole paradoxes for \textit{n}-particle states, and find that each of such paradoxes can be simply associated to an un-colorable solu…
Experimental Examination of Entanglement Estimates
Songbo Xie, Yuan-Yuan Zhao, Chao Zhang +4
Recently a proper genuine multipartite entanglement (GME) measure has been found for three-qubit pure states [see Xie and Eberly, Phys. Rev. Lett. 127, 040403 (2021)], but capturin…
Entanglement swapping and quantum correlations via Elegant Joint Measurements
Cen-Xiao Huang, Xiao-Min Hu, Yu Guo +8
We use hyper-entanglement to experimentally realize deterministic entanglement swapping based on quantum Elegant Joint Measurements. These are joint projections of two qubits onto…
Experimental Demonstration that No Tripartite-Nonlocal Causal Theory Explains Nature's Correlations
Huan Cao, Marc-Olivier Renou, Chao Zhang +7
Quantum theory predicts the existence of genuinely tripartite-entangled states, which cannot be obtained from local operations over any bipartite entangled states and unlimited sha…
Semi-device-independent certification of indefinite causal order in a photonic quantum switch
Huan Cao, Jessica Bavaresco, Ning-Ning Wang +7
We report an experimental certification of indefinite causal order that relies only on the characterization of the operations of a single party. We do so in the semi-device-indepen…
