Research Interests

Geoff's research is primarily concerned with the quantum nature of things - exploring the quantum world, and understanding quantum physics to make it useful for new technologies. He works in the fields of quantum information, quantum computation, quantum measurement, and coherent control of semiclassical systems.

Geoff substantial research experience in the areas of experimental quantum optics and quantum information, and coherent dynamics of ions in solids. He demonstrated one of the first all-optical controlled-NOT gates, and has extended his quantum optics research to numerous quantum information and quantum measurement problems. After postdoctoral and research fellowship positions at Montana State University and the University of Queenland, Geoff joined Griffith University at the beginning of 2006, where he will investigate optical resources for quantum information processing, quantum control and other quantum technologies

Geoff founded the Optical Quantum Information program at the end of 2005. The research is primarily concerned with implementing novel quantum optical measurements, and investigating the interface between photonic qubits and continuous optical quantum systems, with the overall goal of demonstrating and quantifying new resources for quantum information processing and related quantum technologies.
