Causality relations and hidden variable theories for the Mermin-Peres square

It is well-known that eigenvalues in quantum mechanics cannot be assigned to physical properties independently of the measurement context. We argue that it might be possible to relate the contexts of the Mermin-Peres magic square using causality relations in a way which makes explanations using hidden variable models unnecessary and unappealing.

This article discusses the issue of eigenvalues in quantum mechanics and proposes a possible solution through causal relations, which eliminates the need for and appeal of hidden variable models.
