State-independent contextuality sets for a qutrit
Zhen-Peng Xu, Jing-Ling Chen, Hong-Yi Su
We present a generalized set of complex rays for a qutrit in terms of parameter , a -th root of unity. Remarkably, when , the set reduces to two well known s…
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…
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…
Quantumness of Product States
Jing-Ling Chen, Hong-Yi Su, Chunfeng Wu +1
Product states do not violate Bell inequalities. In this work, we investigate the quantumness of product states by violating a certain classical algebraic models. Thus even for pro…
