Jochen Szangolies contributes a novel way of dealing with the problem of the experimental
testability of the Kochen-Specker theorem posed by realistic that is noisy measurements.
Such noise spoils perfect compatibility between successive measurements which however is a
necessary requirement to test the notion of contextuality in usual approaches. To overcome this
difficulty a new extended notion of contextuality that reduces to Kochen-Specker
contextuality in the limit of perfect measurement implementations is proposed by the author
together with a scheme to test this notion experimentally. Furthermore the behaviour of these
tests under realistic noise conditions is investigated.
