But here's the catch: One couldn't actually travel, or even communicate, through these wormholes, said Andreas Karch, a UW physics professor.

Doesn't quantum entanglement have two particles having the same information with each other? Doesn't that require some form of communication?

No. There's no known way to cause a specific effect on one particle that can cause a corresponding effect at the other, ie. no way to put information into one particle that can be detected using the other particle alone. Sharing some information does not require communication.

 

 

I read about this at http://www.mit.edu/newsoffice/2013/you-cant-get-entangled-without-a-wormhole-1205.html, which speaks of the particles "communicating" (in quotes). This is exactly the type of story that pop sci writers screw up, miseducating people. The video in this post--- http://www.scienceforums.net/topic/663-spotting-pseudoscience/page-8#entry781154 ---expresses how I feel better than I can!
