Directors & Program Managers

Prof David Jamieson

Node Manager: Victoria

Program Manager: Single-Ion Implantation

Professor of Physics, The University of Melbourne
BSc (Hons), PhD Melbourne

David has nearly two decades of experience in the use of focused beams of high energy ions for imaging, analysis and fabrication of advanced materials. He did his undergraduate and PhD (awarded in 1985) studies at the University of Melbourne then spent most of the following 4 years on postdoctoral fellowships at the California Institute of Technology and the University of Oxford. He joined the Microanalytical Research Centre in 1989, becoming director in 1996 and Universitas 21 fellow in 1998. In 2000 he joined the Centre for Quantum Computer Technology as manager of the Ion Beam Program where he developed the single ion implantation method to construct arrays of phosphorus atoms in silicon in close collaboration with Centre researchers at UNSW. He became director of the Melbourne node of the Centre when it became an ARC Centre of Excellence in 2003. David is a member of the Editorial Board of the International Journal Nuclear Instruments and Methods in Physics Research B and is the immediate past President of the Australian Institute of Physics.

Prof Steven Prawer

Program Manager: Hybrid Optical-Solid State Quantum Computing

Professor of Physics, The University of Melbourne
BSc (Hons), PhD Monash, DSc Melbourne

Steven has over 20 years experience in advanced materials science and technology, specialising in the interaction of ion beams with materials. His particular interest has been the fabrication, characterisation and modification of carbon-based materials, including diamond and buckminsterfullerene. His research strengths include Raman Microscopy, Advanced Scanning Probe Microscopy and Ion Beam Analysis. He joined the University of Melbourne in 1991. He was attracted to join the SRC by the prospect of being able to use his knowledge of materials, ion implantation and scanning probe techniques to fabricate a prototype solid state quantum computer. Steven was the inaugural director of the Melbourne node of the COE, and now serves on the COE advisory board and IP committee. He is the director of the hybrid opitcal-solid state quantum computing effort whose goal is the use of optical techniques, particularly Raman microscopy, to measure the coupling between phosphorus donors in Silicon.

Dr Jeffrey McCallum

Program Manager: Materials Characterisation Program

Senior Lecturer, The University of Melbourne
BSc (Hons), PhD Melbourne

Jeffrey has 20 years experience in ion implantation and crystallisation effects in semiconductors and ceramics, with particular emphasis on research in silicon. He joined the MARC group of the School of Physics in 1995 as a QEII Fellow and in 2001 was appointed to a lecturing position. He has held a postdoctoral appointment at Oak Ridge National Laboratory and was awarded an International Fellowship by the Canadian government to undertake postdoctoral work at the University of Western Ontario. In 2001, Jeffrey joined the Centre to manage the Materials Science Program whose purpose is to find appropriate processing conditions and annealing regimes which will allow construction of a silicon-based quantum computer.

Prof Lloyd Hollenberg

Program Manager: Device Modelling & Algorithms

Professor and Reader of Physics, The University of Melbourne
BSc (Hons), PhD Melbourne

Lloyd completed his PhD at the University of Melbourne for work on non-perturbative effects in hadronic weak interactions. In 1991 he was awarded a JSPS Fellowship and began postdoctoral work in the theoretical physics group at the KEK accelerator laboratory in Tsukuba, Japan, focusing on Discretised Light Cone Quantisation in field theoretic systems and Quantum Chromodynamics. After his postdoctoral period he returned to the School of Physics where he is now Associate Professor and Reader. A long-standing interest in quantum many body systems, particularly field theoretic and spin systems, was a natural starting point for quantum computing. In 2000 Lloyd joined the Centre, and was appointed Manager of the Device Modelling Program in 2001. This program aims to provide a detailed theoretical description of the P-donor silicon quantum computer, in particular the two qubit device, which may also serve as a guide to the fabrication process.
