Local theories with parallel realities and the epistemic view of the quantum state
Alberto Montina, Stefan Wolf
Hidden-variable theories effectively solve the measurement problem. However, a serious issue of this route towards a realistic completion of quantum theory is raised by Bell's proo…

Quantum-foundational implications of information erasure upon measurement
Alberto Montina, Stefan Wolf
A projective measurement cannot decrease the von Neumann entropy if the outcome is ignored. However, under certain sound assumptions and using the quantum violation of Leggett-Garg…
