Computers are basically machines that process information in the form of electronic zeros and ones. But two MIT professors of materials science and engineering are trying to change that.
Caroline Ross and Geoffrey Beach are members of the Center for Spintronic Materials, Interfaces, and Novel Architectures (C-SPIN), a University of Minnesota-led team of 32 professors (and over 100 graduate students and postdocs) from 18 universities trying to restructure computers from the bottom up. C-SPIN researchers want to use the “spin” of electrons on nanomagnets — rather than electric charge — to encode zeros and ones. If they are successful, the computers of 2025 could be 10 times faster than today’s computers, while using only 1 percent of their energy.
