&gt; I believe this interpretation fails to explain experiments where people have entangled particles with timelike separation [1]<p>I don&#x27;t have time to read that paper right now, but it sounds like simple entanglement transfer, not unlike what is done for &quot;quantum teleportation.&quot;  In any case, the math behind QIT is simply the math of QM, so anything that QM can explain, QIT can explain.<p>[UPDATE:]  There was a published version of the C&amp;A paper but I can&#x27;t look it up right now (I&#x27;m on the road with very limited internet connectivity).  But it turns out that the C&amp;A position is essentially the same as decoherence&#x2F;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 &quot;many-worlds&quot; is highly misleading.
