News of quantum breakthroughs seem to be coming every few months now, edging ever closer towards the hallowed goal of building a quantum computer using quantum qubits rather than classical bits and bringing colossal improvements in computational power. This will eventually lead to applications that we can't even imagine now and possibly a true artificial intelligence of the kind one sees in the movies. Also, it would allow calculations that would normally take longer than the lifetime of the universe on a classical computer to be made in just a few seconds or minutes on a quantum one. A goal well worth striving for.
The latest breakthrough comes from the University of New South Wales, Melbourne University and Purdue University who have developed the smallest wire yet. It's a silicon nanowire, having the tiny dimensions of just one atom high and four atoms wide. This is a feat in itself, but the crucial part is that the wire is able to maintain its
resistivity even at this atomic level, making it far easier for current to flow, thereby preventing the tiny wire from becoming useless. This will help with the continuation of
Moore's Law, giving us ever more powerful computers at the present rate and opens the door to quantum computing within the next decade.
TechEYE has a more detailed article about this development. This is based on an
ABC Radio interview with Michelle Simmons from the University of New South Wales and makes for fascinating listening.
