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 "Logic Gate" that is only one molecule thick. The scientists said in the article in yesterday'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."Very small machines containing vast amounts of resources... may be possible, yet their basic operating and programming principles will be essentially the same as for present systems," they wrote. The researchers created a compound called Rotaxane that they can manipulate at the molecular level.Copyright © 1999 Indian Express Newspapers (Bombay) Ltd.
