PBR, Nonreality and Entangled Measurement

In a recent paper, Cabbolet argues that the PBR theorem is nonreal since in the ensemble interpretation of quantum mechanics the entangled measurement used in the derivation of the PBR theorem is nonexisting.

Summary:In a recent paper, Cabbolet argues that the PBR theorem is nonreal since in the ensemble interpretation of quantum mechanics the entangled measurement used in the derivation of the PBR theorem is nonexisting. However, Cabbolet (1) does not provide any argument for the nonexistence of entangled measurements beyond the incompatibility of the existence of entangled measurements and the existence of ψ -epistemic models which we already know from the PBR theorem; and (2) he does not show why it is more reasonable to abandon entangled measurements instead of ψ -epistemic models. Hence, the PBR theorem remains intact.
