Is quantum state real or just knowledge of some underlying reality? This question has been asked time and time again but the answer still remains unclear. In the following paper, using the property of the entangled state the author shows that the underlying hidden-variable model for a particle in an entangled state has to be psi-epistemic. This implies that the wavefunction can't correspond to reality of such a system where the quantum state is entangled. However the result doesn0t contradict the PBR result which says that quantum state is real as those results do not include entangled systems.
