Observation as Physication. A single-world unitary no-conspiracy interpretation of quantum mechanics

Abstract

The physical meaning of the operators is not reducible to the intrinsic relations of the quantum system, since unitary transformations can find other operators satisfying the exact same relations. The physical meaning is determined empirically. I propose that the assignment of physical meaning to operators spreads through observation, along with the values of the observables, from the already observed degrees of freedom to the newly observed ones. I call this process "physication". I propose that quantum observations are nothing more than this assignment, which can be done unitarily. This approach doesn't require collapse, many-worlds, or a conspiratorial fine tuning of the initial conditions.
