> I believe this interpretation fails to explain experiments where people have entangled particles with timelike separation [1]

I don't have time to read that paper right now, but it sounds like simple entanglement transfer, not unlike what is done for "quantum teleportation." In any case, the math behind QIT is simply the math of QM, so anything that QM can explain, QIT can explain.

[UPDATE:] There was a published version of the C&A paper but I can't look it up right now (I'm on the road with very limited internet connectivity). But it turns out that the C&A position is essentially the same as decoherence/many-worlds. There is essentially no dispute over the facts any more. The problem is with the rhetoric in which those facts are wrapped. Even "many-worlds" is highly misleading.

I'm not sure what you mean by "There is essentially no dispute over the facts any more." As far as I understand, no-one has been able (yet) to make a prediction based on the many-worlds interpretation that could (even in theory, with infinite resources and time) be tested experimentally. Same goes for the Copenhagen interpretation. Thus neither of these are proper scientific theories (in the sense of Popper), and so we call them "interpretations". In light of this I don't understand how you can claim it is settled in favor of one side or the other?

Read my paper. It describes exactly such an experiment.
