A Step Towards Quantum Computing
CARDIFF, Wales, April 21, 2010 — Physicists have discovered properties of hybrid light-matter particles, existing in the solid state matrix, which could one day lead to faster and more efficient computers and telecommunications. A team from Cardiff University’s School of Physics and Astronomy fired light particles, or photons, into a tiny tower of semi-conducting material. A photon collides with an electron confined in an even smaller structure within the tower, and they oscillate briefly between the states of light a...
