Physicists Foretell Quantum Computer With Single-Atom Transistor
Physicists at Purdue University and the University of New South Wales have built a transistor from a single atom of phosphorous precisely placed on a bed of silicon, taking another step towards the holy grail of tech research: the quantum computer.
Revealed on Sunday in the academic journal Nature Nanotechnology, the research is part of a decade-long effort at the University of New South Wales to deliver a quantum computer a machine that would use the seemingly magical properties of very small particles to instantly perform calculations beyond the scope of todays classical computers.
Just last month, the New South Wales team lead by professor Michelle Simmons advanced the cause by demonstrating that Ohms Law of electrical resistivity extends to the world of very small particles, and now, together with Gerhard Klimeck and his team at Purdue, theyve made a more significant breakthrough by placing a single-atom transistor exactly where they want to place it.
