Single Atom Entangled With a Single Photon
In Nature's free section (reg required), Quantum computing gets a step closer: Researchers have created the flying qubit: "Chris Monroe and colleagues from the University of Michigan used a cadmium atom trapped in an electric field to ‘store’ information about the atom's magnetic state. By pumping energy into the atom with a laser, they forced it to spit out a packet of light. That photon carried an imprint of the atom's information with it, which could be read by a detector."
