Flaw may help quantum computers
The new research showed that disturbance, or noise, that currently prevents quantum computers from operating could become the very thing that makes it work. Image: JuSun/iStockphoto The main technical difficulty in building a quantum computer could soon be the thing that makes it possible to build one, according to new research from The Australian National University. Dr André Carvalho, from the ARC Centre for Quantum Computation and Communication Technology and the Research School of Physics and Engineering, part of the ANU College of Physical and Mathematical Sciences, worked with collaborators from Brazil and Spain to come up with a new proposal for quantum computers. In his research, Dr Carvalho showed that disturbance – or noise – that prevents a quantum computer from operating accurately could become the very thing that makes it work. “Most people have experienced some kind of computer error in their life – a file that doesn’t open, a CD that...
