Raytheon Company's (NYSE: RTN) BBN Technologies has achieved a major advance in quantum information technology with the coupling of light and superconductors.

The achievement is described in a paper, "Direct Observation of Coherent Population Trapping in a Superconducting Artificial Atom," that was recently published in Physical Review Letters. Written by three Raytheon BBN physicists,
William R. Kelly, Zachary Dutton, and Thomas A. Ohki, and colleagues John Schlafer and Bhaskar Mookerji, as well as two additional collaborators from the National Institute of Standards and Technology, the paper describes a physics breakthrough that author Zachary Dutton predicted in a paper he published in 2004.
