IBM scientists say that they have taken a big step toward making atom-sized computers.
Andreas Heinrich, a researcher at IBM’s Almaden Research Center in San Jose, Calif., reported that his team had developed a magnetism-manipulating microscope that can create magnetic fields up to 140,000 times stronger than Earth’s magnetic field. Using the process, called “spin-excitation spectroscopy,” the scientists manipulated atoms and measured the effect that their spins had on one another. The results convinced the scientists of the potential of computers on an atomic scale.
Such research is necessary, of course, because sooner or later, the current silicon-based technology will be insufficient to hold what is increasingly more and more information.
