Australian engineers have proven – with the highest score ever obtained – that a quantum version of computer code can be written and manipulated using two quantum bits in a silicon microchip, removing any doubt silicon can be the foundation for a powerful quantum computer.
The world’s first calculation using two quantum bits in silicon has been demonstrated by a team of engineers at UNSW Australia. The manufacturing techniques used are the same as those employed in today’s silicon chip industry, opening the way to ultra-powerful quantum computers.
A major advance on the road to building super fast quantum computers will be announced by UNSW researchers at a news conference to coincide with publication of their work in the global scientific journal, Nature.
A dramatic increase in the amount of time that data can be stored on a single atom means silicon could once again play a vital role in the development of super-fast computers, write Andrea Morello and Andrew Dzurak.
