Connecting Quantum Contextuality and Nonlocality
Jianqi Sheng, Dongkai Zhang, Lixiang Chen
Quantum theory departs from classical physics in its treatment of correlations, most prominently through the phenomena of contextuality and nonlocality. Once regarded primarily as…

Crypto-nonlocality in arbitrarily dimensional systems
Jianqi Sheng, Dongkai Zhang, Lixiang Chen
According to Bell's theorem, any model based on local variables cannot reproduce certain quantum correlations. A critical question is whether one could devise an alternative framew…

Orbital Angular Momentum Experimental Bound on the Maximum Predictive Power of Physical Theories in Multi-Dimensional Systems
Jianqi Sheng, Dongkai Zhang, Lixiang Chen
The completeness of quantum mechanics in predictive power is a central question in its foundational study. While most investigations focus on two-dimensional systems, high-dimensio…
