Quantum wafer (IMAGE) DOE/Sandia National Laboratories Caption Sandia National Laboratories is collaborating with Arizona State University to advance how light can carry quantum information. Instead of using typical large optical tables, Sandia is developing acousto-optic device technologies, such as the eight-inch wafer above, that can selectively reflect different colors of light.
