the first step towards quantum computer

Australian scientists at the university of wisconsin- Medison unveiled the worlds smallest electronic swichof the seven atom transistor measuring four-billionth of a metre and embeded in a single silicon crystal which will bedded in a single silicon crystal which will shrink microchips and revolutionize computing speeds. It is the first step in quantum computer which will make calculations millions of times faster than existing devices . Thetransistor was created by manipulating atams using a special microscope.The breakthrough promises to reduce the size of microchips ,which contain billions of transistor,by up to 100 times
