Exploring the boundary of quantum correlations with a time-domain optical processor
Zheng-Hao Liu, Yu Meng, Yu-Ze Wu +10
Contextuality is a hallmark feature of the quantum theory that captures its incompatibility with any noncontextual hidden-variable model. The Greenberger--Horne--Zeilinger (GHZ)-ty…
