UNSW researchers created new way build quantum computer

Researchers at the University of New South Wales have designed a new quantum computation. A radical new architecture for quantum computing called 'qubit flip-flop' gives the promise of making large-scale quantum chips dramatically easier and cheaper. The new chip design allows silicon quantum processors to increase without atomic placement.

Researchers at UNSW developed a quantum computing system that allows quantum bits or 'qubits' as the basic units of information on quantum computers to be placed apart in hundreds of nanometers and still stay connected.

The new Qubit controlled using electrical signals, not magnetic. Electric signals are significantly more easily distributed and localized in electronic chips, so they can be manufactured using the same device technology as computer chips on the market today.

"This makes the development of quantum computers much more feasible, because it is based on the same manufacturing technology as the computer industry today," said Andrea Morello.

"Our new silicon-based approach is easier to build than atomic-scale devices, but still allows us to place one million qubits in square millimeters," Morello said.

The new approach enables chips for quantum computers to be mass-produced which have so far been missed from other researchers. The research team reports the findings to Nature Communications.
