Those wacky quantum computers

Pretty soon we'll be learning of computing that takes place in another dimension. From ZDNet:

Quantum computing without computing by ZDNet's Roland Piquepaille -- The optical quantum computer designed by researchers from the University of Illinois at Urbana-Champaign (UIUC) can find the answer to an algorithm without running it by using "counterfactual computation." Even the leader of the scientists' team thinks it's bizarre: "To my mind, quantum mechanics doesn't get any more mysterious than this."

I first saw this story in the Chronicle's Wired Campus Blog.
