Deutsch's prescription not involving the many worlds interpretation[edit]
I believe Deutsch's paper has been misinterpreted. The paper does discuss multiple universes, but it clearly states that "the multiple universes terminology is inadequate"; "[multiple universes terminology] is not capable of expressing everything that can happen to quantum systems"; and so on. I believe the equations themselves do not invoke the many-worlds interpretation, and furthermore that Deutsch found the interpretation inadequate. In and of themselves, you could apply other interpretations to Deutsch's equations, and his "version of time travel" does not seem to involve multiple universes to me, despite claims from competing physicists who offer different views.
