Physicists Create a Working Transistor From a Single Atom

Physicists Create a Working Transistor From a Single Atom - NYTimes.com: "Australian and American physicists have built a working transistor from a single phosphorus atom embedded in a silicon crystal.  The group of physicists, based at the University of New South Wales and Purdue University, said they had laid the groundwork for a futuristic quantum computer that might one day function in a nanoscale world and would be orders of magnitude smaller and quicker than today’s silicon-based machines."
