Three Solutions to "Measurement Problems"
- The Collapse Dynamics Are Not Part of the Formalism
- If the collapses were a part of the dynamical evolution of the quantum system, it would not be quantum mechanics.
- Quantum mechanics is irreducibly statistical and indeterministic.
- The Schrodinger (Zeh, Zurek) Objection That We Don't See Macroscopic Superpositions
- In the transition to apparent classicality, large and massive information structures suppress quantum effects. h / m -> 0.
- The Everett (Barrett) Objection That Two Dynamical Laws Are Logically Inconsistent
- The two laws are not simultaneously applied. They are a temporal sequence.
- First von Neumann Process 1, state preparation, with randomness, new information.
- Then Process 2, unitary time evolution, no new information until the next interaction.
