New quantum computing building block developed by Australian researchers
Australian researchers have developed a new building block for a quantum computer, bringing the technology a tantalising step closer. Key points: Australian researchers have made the fastest two-qubit gate that's been demonstrated in silicon Qubit gates involve two electrons interacting with each other, similar to the logic gates you see in conventional computer circuits This is one of the ways the devices are being developed around the world The University of New South Wales team, led by quantum physicist Michelle Simmons, has built the first two-qubit gate between atom qubits in silicon, they report in the journal Nature. "It's a very exciting result in a really difficult physical system to work with," said quantum physicist Andrew White of the University of Queensland, who was not involved in the research. And the University of New South Wales also demonstrated a two-qubit gate in silicon in 2015, when Professor Andrew Dzurak's group used a metal oxide semiconductor device, as opposed to the atom qubits used by Professor Simmons' team. "My personal opinion is that the world yet doesn't have in its hand the perfect qubit that's going to scale up into building a quantum computer," Professor Reilly said.
