A quantum router

A router that sends quantum bits to different destinations based on another quantum signal: as far as I understand it, you can send information to superposed locations. http://www.technologyreview.com/view/428706/first-demonstration-of-a-qua... Original paper: http://arxiv.org/abs/1207.7265 Quantum networking is starting look good. Which is presumably good for quantum hackers too. "OK, we are inside the system. Or not. Both states are superimposed with amplitude 1/sqrt(2), so there is no way of telling which one we would get if we observed things. But now I will do this rotated exploit which will give us access to the data store in some branches. A quick Grover search, and we have the data in most of them. *Then* it is time for the really weird trick..."
