Diamond Shows Promise for Quantum Internet

Diamond Shows Promise for Quantum Internet:
Today's Internet runs on linked silicon chips, but a future quantum version might be built from diamond crystals. Physicists report today in Nature that they have entangled information kept in pieces of diamond 3 meters apart, so that measuring the state of one quantum bit (qubit) instantly fixes the state of the other - a step necessary for exchanging quantum information over large distances.
