Research Interests

I am a Research Fellow in the Device Modeling Program, Centre for Quantum Computer Technology at the University of Melbourne. I work on a wide-range of different topics relating to Quantum Computing (see research interests and publications, below), but my main interest is in what can be done at the few qubit level. In this regard issues such as qubit measurement, adiabatic transfer and single/entangled photon generation have emerged as the most pertinent, although my earlier work on nonlinear optics in electromagnetically induced transparency systems is still an avenue of investigation.

I also lecture part of the Third Year course - Standard Quantum Mechanics, and lecture notes can be obtained on request for appropriate students.

My research interests are in the understanding of quantum coherent properties of matter. I have pursued this study experimentally and theoretically, in a variety of media, initially in the N-V centre of diamond (ANU), laser-cooled rubidium (Open) and now in solid-state qubit systems.

At present my research focuses on novel qubit readout methods, double-island single-electron transistors, modelling of quantum computing architectures, MOSFETs used for device characterisation, Hilbert space optimization, and simulation of quantum computers. I also maintain links with my previous work in laser-spectroscopy and coherent light-matter interactions.
