Chiribella–D'Ariano–Perinotti 2011: five informational axioms plus purification
- what the source states
- Five elementary informational axioms define a broad class of theories; "one postulate—purification—singles out quantum theory within this class." The derivation proceeds without postulating Hilbert space.
- what we infer
- Locates the distinctly quantum content in a single named principle, which is exactly what makes it a target: a Zero Worlds derivation of purification from first-person postulates (research agenda ZW-R003) would be the shortest known path across the bridge.
- limitations
- Why nature satisfies purification is an open explanatory question — the reconstruction relocates the mystery into its axioms, as its critics note.
