Contextuality: At the Borders of Paradox (2011.04899v1)
Published 7 Nov 2020 in quant-ph, cs.LO, and math.CT
Abstract: Contextuality is a key feature of quantum mechanics. We present the sheaf-theoretic approach to contextuality introduced by Abramsky and Brandenburger, and show how it covers a range of logical and physical phenomena "at the borders of paradox".
