Education

Devitt received his BSc (Hons) in Physics from Melbourne University in 2004. He completed his PhD in physics under Lloyd Hollenberg at the Center for Quantum Computation (CQCT) at the University of Melbourne in 2008, with a thesis entitled Quantum information engineering: concepts to quantum technologies.[1] During his Ph.D, Devitt was awarded the Rae and Edith Bennett Travelling Scholarship at the Faculty of Mathematics, University of Cambridge, where he worked within the Centre for Quantum Computation, headed by Artur Ekert.[2]

Career and research

Following his PhD, Devitt did postdoctoral research at the Japanese National Institute of Informatics in the group of Kae Nemoto, where he was promoted to Assistant Professor in 2011. Later, in 2014, he took a position of Associate Professor in physics at Ochanomizu University at the Leading Graduate School Promotion Center. In 2015 he took up a position as Senior Research Scientist at the Japanese National Laboratories, Riken, in the Superconducting Quantum Simulation Research Team, headed by Jaw-Shen Tsai.

In 2017, he returned to Australia where he was appointed Research Fellow for the Australian Research Council Center of Excellence for Engineered Quantum Systems (EQUS) at Macquarie University and in 2018 he was appointed as Lecturer in Quantum Architectures at the Center for Quantum Software and Information (QSI) at the University of Technology Sydney.[3]

Devitt's research has focused on the design of practical large-scale systems architectures for quantum computing and communications system. He published the first architecture, in an atom-optical system, that utilised techniques in topological quantum error correction that could be conceptually scaled to an arbitrary number of encoded qubits.[4] In 2014, in collaboration with NTT Communications and TU Wien, he developed a design for a scalable system using the Nitrogen-vacancy center [5] and in 2017 he developed a large-scale system design for Ion trap quantum computing in collaboration with the University of Sussex.[6] Devitt has also worked in the development of scalable Quantum networks, developing designs for what is now known as 2nd [7] and 3rd[8] generation quantum repeaters and inventing, with scientists in Japan and Australia, a quantum version of Sneakernets.[9]

Devitt's recent work has focused largely on developing a software framework for large-scale, error-corrected machines, including methods to map high-level quantum circuits to machine level instructions[10] and how these error-corrected circuits need to be optimised to reduce the resource load on quantum computing hardware.[11]

In 2016, he established, with Jared Cole of RMIT University, the first consultancy specialising in quantum technology,[12] which became a founding member of the Spanish based industry group, the Quantum World Association (QWA).[13]

He has worked with and advised several companies and government agencies worldwide on quantum technology development, is regularly featured in the popular press, [14][15][16][17][18] and comments for outlets such as New Scientist and MIT Technology Review [19][20][21][22] on developments in quantum technology research.

In 2016, Devitt created and hosts the Meet the meQuanics podcast [23], where scientists, industry leaders and students discuss issues related to the new quantum technology sector.

            gollark: GϘn.
            gollark: Revised description:```Mana courses through this glassy egg, producing a beautiful glow - it's very reflective, almost metallic. It has a red gleam, too, and smells faintly like brine. It shimmers like gold, and it seems as if time is distorted around it. It is much smaller than the other eggs, and looks like lots of pieces of paper folded together and smelling faintly like cheese. It occupies every point in the spacetime continuum.```
            gollark: Oh, forgot it.
            gollark: Reminder: they'll all be omnidragons.
