The significant advance, by a team at the University of New South Wales (UNSW) in Sydney appears in the international journal Nature.

"What we have is a game changer," said team leader Andrew Dzurak, Scientia Professor and Director of the Australian National Fabrication Facility at UNSW.

"We've demonstrated a two-qubit logic gate [sciencedaily.com] -- the central building block of a quantum computer -- and, significantly, done it in silicon. Because we use essentially the same device technology as existing computer chips, we believe it will be much easier to manufacture a full-scale processor chip than for any of the leading designs, which rely on more exotic technologies.

The advance represents the final physical component needed to realise the promise of super-powerful silicon quantum computers, which harness the science of the very small -- the strange behaviour of subatomic particles -- to solve computing challenges that are beyond the reach of even today's fastest supercomputers.
