The Problem of Compatibility in Experimental Tests of Quantum Contextuality — •Jochen Szangolies, Matthias Kleinmann, and Otfried Gühne — Naturwissenschaftlich-Technische Fakultät, Walter-Flex-Str. 3, Universität Siegen

The Kochen-Specker theorem is a famous result in the foundations of quantum mechanics that rules out non-contextual hidden variable models. In such models, individual experimental outcomes are assumed to be independent of jointly performed compatible measurements. It can be expressed in the form of inequalities, which are obeyed by non-contextual models, but violated by quantum mechanics. Recently, several experiments have indeed observed such a violation. However, the interpretation of these tests remains controversial. One of the main reasons for this is that perfect compatibility between measurements is difficult to achieve in any real experiment. We approach this issue by modelling the typical effects of experiment-induced noise on measurement compatibility. Furthermore, we investigate the possibility of improving the bounds for non-contextuality, taking these effects into account.
