Researchers at the California Institute of Technology (Caltech) have demonstrated quantum entanglement for a quantum state stored in four spatially distinct atomic memories. Their work, described in the November 18 issue of the journal Nature, also demonstrated a quantum interface between the atomic memories"”which represent something akin to a computer "hard drive" for entanglement"”and four beams of light, thereby enabling the four-fold entanglement to be distributed by photons...
