Personal Details

Associate Professor
Family Name

Dr Stace completed his PhD at the Cavendish Lab, University of Cambridge in the UK on quantum computing, followed by postdoctoral research at the Department of Applied Mathematics and Theoretical Physics, also at Cambridge. During this time he was a fellow at Queens' College, known for its eclectic mix of medieval, tudor and victorian architecture. He has been a researcher at the University of Queensland since 2006, firstly on an ARC Postdoctoral Research Fellowship, then on an ARC Research Fellowship, and was awarded an ARC Future Fellowship in 2014.

His research has largely focused on applying methods from quantum optics to solid state devices for use in quantum information applications, and more recently on error correction protocols. He also works on high precision measurement in collaboration with experimental colleagues at UWA, in a project whose ultimate aim is to contribute to the international definition of Boltzmann's constant, and some biophysics.

Dr Stace also consults for UniQuest, UQ's commercial arm, on scientific and technical matters.

Quantum Computers Easier to Build: Can Tolerate Faulty or Missing Components, Researchers Say, Science Magazine Daily News
Together with his colleague Sean Barrett, Dr Stace discoverd that quantum computers can tolerate very high levels of different kinds of errors, including qubit loss, and computational faults, simultaneously. One can still build a fully functional quantum computer even if 25 percent of the constituent qubits are missing. Try driving your car with a quarter of its wheels missing! (paper)

The road to a better thermometer is full of potholes, Ars Technica
Given limited resources, it has long been known that time and space can be measured more accurately if you take advantage of quantum tricks. Dr Stace was surprised to discover that temperature, which quantifies noise and disorder and seems to make things "less quantum", can also be measured more accurately using the same kinds of tricks. (paper)

Quantum computers still work with half their bits missing, Cosmos Magazine
In this paper, Dr Stace showed that a quantum memory can still function even if half of its qubits are lost, and up to 10 percent of them suffer "computational" errors. Quantum systems aren't quite as sensitive as he first thought! (paper)
