Researchers work to build error-proof quantum computer

Following on from their success in an international quantum computing research collaboration, Griffith University scientists have secured a further $2M from the Department of Defence’s Next Generation Technologies Fund (NGTF).

‘Quantum Control Based on Real-Time Environment Analysis by Spectator Qubits’, led in Australia by Dr Gerardo Paz Silva, from Griffith’s Centre for Quantum Dynamics aims to create knowledge that may one day enable error-tolerant quantum computers.

In conjunction with the University of Technology Sydney and the University of New South Wales, the research is part of the Defense Australia-US Multidisciplinary University Research Initiative (AUSMURI). This initiative partners leading universities in Australia with a team of top universities in the US, in this case led from Duke University.

Co-chief investigator Dr Paz Silva says quantum-enabled technologies promise to revolutionise the way we process and store information.

“This project is taking the next crucial step towards a viable application of these technologies,” he said.

“It will assess and experimentally implement a novel paradigm using spectator quantum systems for better control of qubits (basic unit of quantum information) for quantum computing.

“Basically, we want to build noise cancelling headphones for our qubits.”

“As well as our theory team at Griffith, this funding will support our Australian collaborators” said co-chief investigator and Director of the Centre for Quantum Dynamics, Professor Howard Wiseman.

“The experiments are being conducted at the University of New South Wales, with input from experts in machine learning at University of Technology, Sydney.”

“In the first phase of the AUMURI project we demonstrated that the spectator qubit paradigm is viable in principle. In this new phase we aim to put the theory into practice.”

Dr David Kershaw from the Department of Defence said the project had provided ground-breaking advances in quantum sensing and control.
