Smallest computer chip developed

WASHINGTON, JULY 17: The possibility of building computers no bigger than a grain of sand but billions of times faster than existing machines is a little closer to reality, according to an article published in the journal Science. Researchers at the University of California at Los Angeles and Hewlett-Packard created a computer switch called quot;Logic Gatequot; that is only one molecule thick. The scientists said in the article in yesterday8217;s issue of the journal that this advance opens up new possibilities for making computer chips billions of times smaller and faster than existing ones.quot;Very small machines containing vast amounts of resources8230; may be possible, yet their basic operating and programming principles will be essentially the same as for present systems,quot; they wrote. The researchers created a compound called Rotaxane that they can manipulate at the molecular level.
