I showed this article to a friend of mine who did a PhD in physics at Cambridge. Here's what he had to say:

The entanglement arguments against relativity are fairly silly. From that article, looks like Scientific American is going the way of the New Scientist. :( Absolutely no mention of Everett and his MWI (editor's note: multiple worlds interpretation) in the article I notice. Even though that's the most obviously straightforward way of keeping special relativity, locality, quantum mechanics and accounting for the Aspect experiment. Basically Bell's theorem that is supposed to prove non-locality makes a subtle assumption called "counter-factual definiteness", which implies among other things that experiments have definite outcomes. Obviously it's violated by MWI. Really it's only Bohmian mechanics that's non-local and arguably not consistent with SR. Though Bohm adherents often claim that Copenhagen must be non-local by Bell's theorem, they misunderstand the fact that the wavefunction in CI is really an epistemic device and wavefunction collapse isn't thought to be a genuine physical occurrence except by a very small minority. CI when viewed in this way doesn't satisfy counter-factual definiteness either.




Hear hear.

The article doesn't say what's new about the authors' ideas. You'd expect it to mention the transactional interpretation of quantum mechanics - it isn't news that the Aspect experiment can be explained if measurements affect things that happened earlier.
