Photons create primitive quantum network Two teams of physicists have stored a single photon of light in an atomic assembly, transferred it to another atomic cloud and then retrieved it again -- all without losing the photon's quantum character. The results are the first demonstration of a simple quantum communication or computation network, which stores and processes information using atoms and photons. Meanwhile, a third research group has shown that a stored atomic state can be transferred to an "entangled" state of light.
