The new approach turns a silicon transistor into an “artificial atom.”

Australian scientists have developed the first silicon quantum technology capable of holding data with over 99 per cent accuracy.
The breakthrough, reported in two papers published in the journal Nature Nanotechnology, was achieved using two different types of silicon-based quantum bits or qubits, the basic information storing element in a .


We’re still a long way from donning real invisibility cloaks, but by working out a better way to bend light, scientists from the University of Rochester can make movable objects invisible to the viewer — multi-directionally, and in three dimensions. 

“We have demonstrated that with silicon we can have the accuracy needed to build a real quantum computer,” says Professor Andrew Dzurak of the University of New South Wales, who is one of the authors on both papers.
