New silicon chip could blaze a trail for quantum computing

Engineers at Australia's University of New South Wales (UNSW) are using the nucleus of a single silicon atom as the base for a new "qubit" – the building block for quantum computers – which promises dramatic increases in future data processing capability.

The Australian silicon qubit is said to rival "what many consider to be today's best quantum bit – a single atom in an electromagnetic trap inside a vacuum chamber." This vacuum chamber "Ion Trap" technology won the 2012 Nobel Prize in physics.

The UNSW engineers claim that their qubit "operates at a similar level of accuracy" as the "Ion Trap" but is superior because it is "more compatible with existing industry technology and is more easily scaleable…silicon is the dominant material in the microelectronics industry."
