Nanoscale logic machines go beyond binary computing

Nanoscale logic machines go beyond binary computing



Scientists have built
tiny logic machines out of single atoms that operate completely
differently than conventional logic devices do. Instead of relying on
the binary switching paradigm like that used by transistors in today's
computers, the new nanoscale logic machines physically simulate the
problems and take advantage of the inherent randomness that governs the
behavior of physical systems at the nanoscale—randomness that is usually
considered a drawback.
