Ah, that's the sketchy-at-best popular description of entanglement rather than anything to do with this experiment in particular. It's wrong in that it's meant

Ah, that's the sketchy-at-best popular description of entanglement rather than anything to do with this experiment in particular. It's wrong in that it's meant for a lay audience, and to a lay audience (I think I've heard that the quantum folks define it differently?) the word "affect" implies things like causality and information transfer.
