Revisiting the admissibility of non-contextual hidden variable models in quantum mechanics
Atul Singh Arora, Kishor Bharti, Arvind
We construct a non-contextual hidden variable model consistent with all the kinematic predictions of quantum mechanics (QM). The famous Bell-KS theorem shows that non-contextual mo…
