Abstract
We present a simple experimental scheme which can be used to demonstrate an all-or-nothing–type contradiction between noncontextual hidden variables and quantum mechanics. The scheme, which is inspired by recent ideas by Cabello and García-Alcaine, shows that even for a single particle, path and spin information cannot be predetermined in a noncontextual way.
