My research interest is in condensed matter physics, in particular quantum electronics, at the School of Physics. I work on quantum computation in silicon in the ARC Centre for Quantum Computation and Communication Technology. In a team of enthusiastic researches we work on gaining atomistic insight into the interactions of quantum objects, like atoms and qubits, with their environment. This allows us to manipulate quantum information and minimise decoherence. Before joining UNSW in 2011 I worked at the Kavli Institute for Quantum Nano Science at Delft University and Stanford University.
My Research Goals
- Control entanglement in a solid-state system, i.e. qubits
- Study the interaction between qubits and light
- Build and control molecular states in a solid with atomic precision
My Research in Detail
The goal of my research program is to understand the physics of qubit coupling with the environment to understand decoherence pathways and to control. The control over the electron wavefunction requires interface which lead to the loss of bulk properties of the qubit due to physical processes like the valley-orbit coupling, exchange, and many-body effects in coherent coupling. The atomistic understanding of the interaction between the environment and the qubit is essential for quantum computation since it allows the achievement of optimal coherence times and optimal robustness of the quantum gates. Optical addressing of electrons in Si is nontrivial but vastly beneficial due to the gained flexibility and unprecedented high resolution. We investigate efficient read-out and coupling schemes to open up new pathways into optical control.
Current Student Projects (PhD and Honours)
We look for enthusiastic PhD and Honours candidates for research projects. Prestigious Scholarship are available which are typically valued at $28,000 per annum with a supplement of up to $5000 per annum for first class honours or equivalent and is available for up to three-and-a-half years. The successful scholarship applicant will be expected to enrol for a PhD degree and should have an honours degree (level 1 or 2A) or equivalent, in Physics, Applied Physics, Material Science or a related subject. International applicants with a Masters degree are strongly encouraged to apply. Interested candidates should contact me to discuss possible projects and the application procedure. International applicants are very welcome! Please email an application containing a complete resume including telephone numbers, email address, and contact details of three academic referees to me. You will get a confirmation within a few days. The scholarships will remain open until filled.
There are always projects in the main research areas which focus on low temperature scanning-tunnelling spectroscopy, atomistic transport, and the interaction of light and matter at the atomic scale. We have a team of 15 enthusiastic researchers ranging from undergraduates to postdoctoral fellows. My group combines different research strengths and is very international. UNSW offers a first class laboratory and intellectual environment for atomic-scale electronics research.
