Researchers at a European research facility called the Nanoscience and Picotechnology Group are working on computing at a molecular level. We’re talking a handful of atoms here– way, way smaller than even nanotechnology.
A snippet from the article I just read:
Holy cow. Amazing stuff. The research is pretty fundamental right now– nothing that’s going to become a commercial product for several years at least– but just the fact that they can potentially build CPUs a millionth (or less) the size of current semiconductor chips could mean that in a decade we may literally have computers more powerful than today’s supercomputers in a box the size of, say, a grain of sand.
