Physical interpretation of nonlocal quantum correlation through local description of subsystems
Tanumoy Pramanik, Xiaojiong Chen, Yu Xiang +11
Characterization and categorization of quantum correlations are both fundamentally and practically important in quantum information science. Although quantum correlations such as n…
Quantum Steering: Practical Challenges and Perspectives
Yu Xiang, Shuming Cheng, Qihuang Gong +2
Einstein-Rosen-Podolsky (EPR) steering or quantum steering describes the "spooky-action-at-a-distance" that one party is able to remotely alter the states of the other if they shar…
Characterizing Multipartite Non-Gaussian Entanglement for Three-Mode Spontaneous Parametric Down-Conversion Process
Mingsheng Tian, Yu Xiang, Feng-Xiao Sun +2
Very recently, strongly non-Gaussian states have been observed via a direct three-mode spontaneous parametric down-conversion in a superconducting cavity [Phys. Rev. X 10, 011011 (…
Experimental demonstration of remotely creating Wigner negativity via quantum steering
Shuheng Liu, Dongmei Han, Na Wang +7
Non-Gaussian states with Wigner negativity are of particular interest in quantum technology due to their potential applications in quantum computing and quantum metrology. However,…
Experimentally ruling out joint reality based on operational completeness
Qiuxin Zhang, Yu Xiang, Xiaoting Gao +9
Whether the observables of a physical system admit real values is of fundamental importance to a deep understanding of nature. In this work, we report a device-independent experime…
