Hewlett-Packard is betting that it can build computers whose functionality rests on the workings of individual molecules. It’s blue-sky research, but if it works, it will push computing far beyond the limits of silicon.
A chip in which silicon transistors are replaced with molecular devices could in principle be fabricated through a simple chemical process. A circuit with 10 billion switches could eventually fit on a grain of salt;… read more
