World's Smallest Silicon Wire Leads To Atomic-Scale Computing, Moore's Law Continues

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.

I wonder if Moore's law will continue to hold after we reach the sub-atomic level? What could be smaller than the single electron transistor? And if that's the limit, we just gonna build bigger and bigger chips until we finally drop this whole technology out of the window and start everything over on a different field (like organic computing or whatnot)?

At our present state, humans are like socialised animals, but just that and we can do much more when evry human beeing got it's personal AI with native human-machine interface. Imagine lerning to compose music like Mozart in two days, or understanding every given subject in it's whole complexity.

forget skynet, we already have the bilderberg group... hows everyone enjoying their latest recession...

if this tech becomes possible you can wave goodbye to the idea of a free world...

youll be living in the 'new world order'.... a free slave... free to do whatever bilderberg want...IMO!!!!!
