Measurement incompatibility vs. Bell non-locality : an approach via tensor norms

Faedi Loulidi (LPT)

par Revaz Ramazashvili - 26 avril

Incompatibility of quantum measurements and Bell inequality violations are two key features of quantum theory. It is known that the violation of the CHSH inequality is equivalent to the incompatibility of two binary quantum measurements. We explore when this phenomenon generalizes to other Bell inequalities and multiple binary measurements. We introduce tensor norms which fully characterize measurement incompatibility and violations of a general Bell inequality. By comparing these norms, we characterize the scenarios where the two manifestations of quantumness are equivalent.
