NewScientist: A trick for transferring quantum information from atoms to photons and back again could be used to create impenetrable global communication networks and computers that work at astounding speeds.

“…the technique could also be harnessed to build a quantum computer, by passing information from one part of the machine’s memory to another. Quantum particles can exist in more than one state at once, meaning quantum computers should, in theory, be able to perform billions of calculations simultaneously.”
