Scientists have created the world’s smallest electronic switch

The world’s smallest transistor built with just seven atoms in a single silicon crystal and measuring four nanometres in length.The transistor, measuring four-billionths of a metre and embedded in a single silicone crystal, is the first step in a “quantum computer” which will make calculations millions of times faster than existing devices. Publishing their findings in the journal Nature Nanotechnology, the scientists from the University of New South Wales said the new device could eventually lead to an exponential jump in computing power.
The process has yet to be commercialised, but it’s thought that if the transistors could be made in large numbers it could lead to computer chips over one hundred times smaller than current processors.
