Conditional evolution requires additional hypotheses
The finite destructive clock instrument › Conditional evolution requires additional hypotheses · lines 1567–1576
This is the precise finite conditioning comparison associated with Page–Wootters and En09-A PageWootters,CheungEn09. Stationarity alone is insufficient for an arbitrary reading basis. For a referenced conditional-evolution statement, stationarity must hold on the full referenced preparation. None of these assumptions is imposed automatically on the Ramsey preparations.
