An experimental test of noncontextuality without unphysical idealizations

An experimental test of noncontextuality without unphysical idealizations

No noncontextual hidden-variable model can be consistent with quantum theory, but proving such an inconsistency with nature itself is a long-standing problem. Here, the authors devise experimentally-achievable tests of noncontextuality and perform a photonic implementation that rules out such models...
