Masanes-Galley-M\"uller and the State-Update Postulate

Quantum Physics 2023-02-21 v2 History and Philosophy of Physics

Abstract

Masanes, Galley and M\"uller claim to have derived a unique rule for quantum state update consequent upon a measurement outcome. Upon closer examination, their proof implicitly assumes its first step, namely that the state-update rule is linear.
