A Bell inequality Analogue in quantum measure theory Speaker(s): Joe Henson
Abstract: In stochastic treatments of the ERRB setup, it is equivalent to impose Bell's inequalities, a local causality condition, or a certain "noncontextual hidden variables" condition. But these conditions are violated by quantum mechanics. On the other hand, it is possible to view quantum mechanics as part of "quantum measure theory", a generalization of probability measure theory that allows pair wise interferences between histories whilst banning higher order interference. In this setting, is may be possible find quantum analogues of the three stochastic conditions.
Following this line of inquiry, we will see that quantum measure theory allows no stronger violations of Bell's inequalities than does standard quantum theory. We also gain some insights into how to define causality in quantum theory.
