Nano-transistor breakthrough to offer billion times faster computer

Sydney scientists have built the world’s tiniest transistor by precisely positioning a single phosphorus atom in a silicon crystal.

The nano device is an important step in the development of quantum computers — super-powerful devices that will use the weird quantum properties of atoms to perform calculations billions of times faster than today’s computers.

Michelle Simmons, of the University of NSW, said single atom devices had only been made before by chance and their margin of error for placement of the atom was about 10 nanometres, which affected performance.

Her team was the first to be able to manipulate individual atoms with exquisite precision — via redwolf.newsvine.com
