Physicists demonstrate new way to violate local causality

(Phys.org)--For the first time, physicists have experimentally demonstrated the violation of "bilocal causality"--a concept that is related to the more standard local causality, except that it accounts for the precise way in which physical systems are initially generated. The results show that it's possible to violate local causality in an entirely new and more general way, which could lead to a potential new resource for quantum technologies.
