InfoWorldMike writes "IBM has demonstrated how to perform computer functions on single atoms and molecules, a discovery that could someday lead to processors the size of a speck of dust, the company said Thursday. Researchers at IBM's Almaden Research Center in California developed a technique for measuring magnetic anisotropy, a property of the magnetic field that gives it the ability to maintain a particular direction. Being able to measure magnetic anisotropy at the atomic level is a crucial step toward the magnet representing the ones or the zeroes used to store data in binary computer language. In a second report, researchers at IBM's lab in Zurich, Switzerland, said they had used an individual molecule as an electric switch that could potentially replace the transistors used in modern chips. The company published both research reports in Friday's edition of the journal Science."
