"The standard interpretation of entanglement is that there is some kind of instant communication happening between the two particles."

This is flat-out not true. The standard interpretation is that the entangled objects are part of a single quantum state. Measurement/observation of the state collapses the wave-function, and does not necessarily imply communication between the constituent parts.

Agreed. This[1] xkcd comic applies to almost every Nautilus article I've ever seen.

I read that to be more like "the naive interpretation of entanglement". The author even spends the remainder of the paragraph reminding (or educating) the reader that faster-than-light communication is not possible, and then the rest of the article is exploring retrocausality as another mechanism to explain entanglement with violating FTL restrictions.

Unrelated Query: How can something be "flat out not true" if it's only an interpretation? Seems to be that what you're describing is a consensus or popular view opposed to a hard fact or universal truth.

I think that chakademus meant that it is flat-out not true that "the standard interpretation … is that there is some kind of instant communication happening between the two particles" (notice the scope of the quotation marks); that is, that this is not the standard interpretation, not that this interpretation is 'wrong' (whatever that means).

Sort of depends on your view of the reality of the wave function, in light of its maybe-interpreted-as faster than light collapse.
