DARPA creates first 1THz computer chip, earns Guinness World Record

DARPA, the US military’s R&D division, has been awarded a Guinness World Record for creating the world’s fastest solid-state chip, clocked at one terahertz — or 1,000 gigahertz, if that’s easier to digest. DARPA’s chip handily beats out the previous record holder, which was only capable of a paltry 850GHz. Computers and radio systems that operate up in the terahertz range have some very interesting and powerful properties, from the creation of hand-held tricorders and security scanners, through to wireless networks that are hundreds of times faster than 2.4 and 5GHz WiFi.

DARPA has been interested in terahertz chips for a long while now — not so much for super-fast computers (though they are being looked at), but for creating radio waves in the sub-millimeter-wave terahertz range. These waves (sometimes called T-rays), as far as the military are concerned, are a prime way of supercharging everything from radar, to imaging and reconnaissance, to ultra-high-bandwidth wireless networks. Basically, because the wavelength of T-rays are so short (less than a millimeter), they can provide much higher resolution than, say, conventional radar, which uses frequencies of a much longer wavelength (anywhere from 100 meters to a few centimeters). The density of T-rays makes them very good for carrying large amounts of data, too — and, as an added bonus, they’re very good at safely penetrating a few millimeters of skin (yes, airports are interested in terahertz security scanners).
