A team of Australian engineers has built a quantum logic gate in silicon for the first time, making calculations between two qubits of information possible – and thereby clearing the final hurdle to making silicon quantum computers a reality.
The significant advance, by a team at the University of New South Wales (UNSW) in Sydney appears today in the international journal Nature.
“What we have is a game changer,” said team leader Andrew Dzurak, Scientia Professor and Director of the Australian National Fabrication Facility at UNSW.
