Demonstrating quantum contextuality of indistinguishable particles by a single family of noncontextuality inequalities
Hong-Yi Su, Jing-Ling Chen, Yeong-Cherng Liang
Quantum theory has the intriguing feature that is inconsistent with noncontextual hidden variable models, for which the outcome of a measurement does not depend on which other comp…
Dimension-Independent Bounds for Hardy's Experiment
Zhen-Peng Xu, Hong-Yi Su, Jing-Ling Chen
Hardy's paradox is of fundamental importance in quantum information theory. So far, there have been two types of its extensions into higher dimensions: in the first type the maximu…
Quantum Nonlocality Enhanced by Homogenization
Xu Chen, Hong-Yi Su, Zhen-Peng Xu +2
Homogenization proposed in [Y.-C Wu and M. Żukowski, Phys. Rev. A 85, 022119 (2012)] is a procedure to transform a tight Bell inequality with partial correlations into a full-corre…
Beating the Clauser-Horne-Shimony-Holt and the Svetlichny games with Optimal States
Hong-Yi Su, Changliang Ren, Jing-Ling Chen +6
We study the relation between the maximal violation of Svetlichny's inequality and the mixedness of quantum states and obtain the optimal state (i.e., maximally nonlocal mixed stat…
Beyond Gisin's Theorem and its Applications: Violation of Local Realism by Two-Party Einstein-Podolsky-Rosen Steering
Jing-Ling Chen, Hong-Yi Su, Zhen-Peng Xu +5
We demonstrate here that for a given mixed multi-qubit state if there are at least two observers for whom mutual Einstein-Podolsky-Rosen steering is possible, i.e. each observer is…
Test of Einstein-Podolsky-Rosen Steering Based on the All-Versus-Nothing Proof
Chunfeng Wu, Jing-Ling Chen, Xiang-Jun Ye +4
In comparison with entanglement and Bell nonlocality, Einstein-Podolsky-Rosen steering is a newly emerged research topic and in its incipient stage. Although Einstein-Podolsky-Rose…
