Is it true that quantum contextuality proves measurement outcomes cannot be assigned non-contextual pre-existing values?

Yes. Quantum contextuality, as demonstrated by the Kochen-Specker theorem, proves that measurement outcomes in quantum mechanics cannot be explained by non-contextual hidden variable theories.

The analysis

The retrieved literature (such as papers 2, 3, and 8) explicitly discusses how the Kochen-Specker theorem and quantum contextuality rule out non-contextual hidden variable models where measurement outcomes are assigned pre-existing non-contextual values. Therefore, the claim is strongly supported by foundational results in quantum mechanics.

Hypergraph framework for irreducible noncontextuality inequalities from logical proofs of the Kochen-Specker theorem

2020

The paper explains that the Kochen-Specker theorem reveals an inconsistency between quantum theory and any putative underlying hidden variable model that satisfies KS-noncontextuality.
