School of Physics Experimental Condensed Matter Physics (ECMP)

Research Programs

ECMP has two major research projects directed at the development of quantum technologies.   Within each major research project there are a series of allied research programs that explore key fundamental issues in solid state and optical materials and devices for information processing and communications.  These major research projects build on our established expertise in the application of ion beam physics to the modification and analysis of advanced materials.
We host a program staffed by personnel from the CSIRO Division of Exploration and Mining who share time on our 5 MeV Pelletron accelerator and collaborate on a program directed at the analysis of geological materials.


ECMP Programs

Diamond Program

Program Manager: Prof Steven Prawer

This program is strongly allied with the aims of the Centre programs but aims to investigate the use of colour centres in diamond to construct quantum devices with novel attributes. There are strong analogies with the Si:P programs, but with the N-V colour centre in diamond replacing the P atom in silicon. 

Materials Program

Program Manager: A/Prof Jeff McCallum

The aim of this program is to investigate the types and quantities of defects introduced into silicon and germanium under the processing conditions used to fabricate quantum computer devices by the top-down approach and to investigate methods of defect minimisation.

Centre for Quantum Computing and Communication Technology

Deterministic Atom Implant

Program Manager: Prof David Jamieson

The ion beam program is part of the top-down strategy for construction of quantum devices from silicon doped with single phosphorus atoms by the implantation of single phosphorus atoms and clusters of phosphorus atoms into silicon.  This is accomplished with a precise single ion implantation method that counts single implanted atoms.  We employ this method to mass-produce devices containing pairs of atoms or clusters of atoms.  We are working towards the development of methods for scaling up the process to create arrays of single atoms and for applying the single ion counting method to some new applications in quantum electronics.

Quantum Device Theory and Applications

Program Manager: Prof Lloyd Hollenberg (TCMP)

The main objectives of the program are to develop realistic and comprehensive theoretical descriptions of the Si:P buried dopant charge and spin devices, and all facets of their operation. Theoretical modelling relevant to the short, medium and long-term goals provides crucial information on device design parameters to the experimental programs. To this end the device modelling program has been active in a number of projects including; fundamental solid-state physics of the Si:P donor system, single and coupled qubit operations, the effects of decoherence, large scale simulations of the actual implementation of quantum error correction and algorithms on arrays of qubits, and investigations of new paradigms of quantum computing.
