Technology Research News December 11, 2002 Eric Smalley	Design links quantum bits Realizing the potential of phenomenally fast quantum computers means having to link thousands of quantum bits, which are the transistors of such computers. So far researchers have been able to connect only a few. A scheme for linking many tiny superconducting loops may pull it all together.
