Record-Breaking Quantum Contextuality Observed in Single System
The schematic diagram for extracting contextuality from three-party nonlocality. Credit: Image by Zheng-Hao Liu, et al.A team of scientists studied the single-system version of multipartite Bell nonlocality, and observed the highest degree of quantum contextuality in a single system. Their work was published in Physical Review Letters. They were led by Prof. Chuanfeng Li and Prof. Jinshi Xu from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), collaborating with Prof.…
