US scientists have unveiled the world's fastest silicon chip. The new chip can operate at speeds of up to 500 GHz, which is 100 times faster than a computer chip and 250 times more than a mobile phone chip (mobile phone). To set this world record, scientists from IBM Computer Group and Georgia Institute of Technology cooled the chip at a temperature of about - 2330C.

Experts believe that the new chip can help speed up wireless networks and reduce the cost of making mobile phones.
