CQC2T Director Professor Michelle Simmons is Australian of the Year 2018

On behalf of all researchers and partners of CQC2T, we congratulate Scientia Professor Michelle Simmons, who was tonight named 2018 Australian of the Year in recognition of her pioneering research and inspiring leadership in quantum computing.

Professor Simmons, who is a UNSW Professor of Physics and Director of the Australian Research Council Centre of Excellence for Quantum Computation and Communication Technology based at UNSW, was awarded the honour by the Australian Prime Minister, Malcolm Turnbull, at a ceremony at Parliament House in Canberra.

Chair of the Centre Advisory Committee, Peter Yates AM said “Michelle’s achievements and those of her team are hugely exciting for the recognition of science in Australia. Her leadership of the Centre and her field is an inspiration to us all’.

As Centre Director she leads a team of more than 200 researchers at eight Australian universities who are developing a suite of technologies for quantum computing, information storage and communications.

Dr Jacq Romero named L'Oréal Australia women in science fellow

Dr Jacq Romero, a researcher in CQC2T's photonic quantum computation program at the University of Queensland, has been named one of five L'Oréal Australia women in science fellows. Romero was recognised for her work creating quantum “alphabets” using the orbital angular momentum of light.

CQC2T congratulates Dr Romero and the four other fellows.

Large-scale quantum circuitry challenges can be overcome for electron spin qubits in quantum dots or donors

Prof Andrew Dzurak and Prof Andrea Morello have contributed to a review of approaches to quantum circuitry for semiconductor spin qubits showing that electron spin qubits in quantum dots or donors offer several opportunities to overcome the challenge of wiring up large qubit arrays.

Sparse qubit array with local electronics

The review was published in npj Quantum Information and concludes that continuous development of semiconductor technology is paving the way for the construction of a large-scale universal quantum computer.

CQC2T researchers are connecting up the global quantum internet

A team of researchers led by A. Prof Matthew Sellars at The Australian National University have shown that an erbium-doped crystal is a practical building block for a global quantum internet.

The material is uniquely suited to enable a global quantum telecommunications network, achieving coherence times of more than a second and operating in the same 1550nm band as existing fibre optic networks.

CQC2T researchers propose new type of qubit

Prof Andrea Morello and his team at UNSW has developed a new architecture for quantum computing, based on novel ‘flip-flop qubits’, that promises to make the large-scale manufacture of quantum chips dramatically easier.

“What the team have invented is a new way to define a ‘spin qubit’ that uses both the electron and the nucleus of the atom. Crucially, this new qubit can be controlled using electric signals, instead of magnetic ones," said Prof Morello.

Quantum sheds new light on electron spin resonance techniques

A team led by CQC2T's Prof Lloyd Hollenberg at the University of Melbourne have demonstrated a dramatically improved electron spin resonance technique using the quantum properties of diamond.

Hollenberg led an interdisciplinary team that improved the sensitivity of ESR by orders of magnitude compared to existing techniques using a non-invasive method. The technology will be used to understand biochemistry and could reveal how transition metal ions affect brain health.

Researchers find quantum computations could be hidden

CQC2T's Dr Nick Menicucci is part of a team that have proposed cloud-based quantum computers could be used remotely without revealing the user's purpose and without the user having access to their own quantum resources.

The work, published in Physical Review X, was part of a collaboration with researchers from the Centre for Quantum Technologies at the National University of Singapore and the Singapore University of Technology and Design. The team propose that concealing which steps in a series perform the desired calculation would be akin to hiding a needle in a haystack.
