GRIN plasmonics
— 25 Jan 2011 18:32 | TechnologyThey said it could be done and now they've done it. What's more, they did it with a GRIN. A team of researchers with the U.S. Department of Energy (DOE)'s Lawrence Berkeley National…
NIST advances single photon management for quantum computers
— 21 Jan 2011 19:59 | TechnologyThe quantum computers of tomorrow might use photons, or particles of light, to move around the data they need to make calculations, but photons are tricky to work with. Two new papers…
