Quantum Entanglement Suggests Time Travel is Possible

Is there a way to work this article in here? It looks like relatively new information (2011) with fairly wide press coverage.

Deutsch's prescription not involving the many worlds interpretation

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.

Applied instead to the state vector, the same rule gives nonunitary physics with a dual description in terms of post-selection.

WTF does this mean? It's OK, don't tell me. Whatever the meaning is should be apparent from the text; all that is required of the reader is a half-competent brain, not a doctorate in quantum physics! Wiki editors, please bear in mind that these articles are for the consumption of ordinary carbon-based lifeforms, and make the information contained therein reasonably comprehensible!
