Established in 2003, the Centre for Quantum Dynamics undertakes world-leading research in quantum science and technology

The Centre comprises more than 50 researchers—including theorists and experimentalists—with strong collaborations. Our cutting-edge research encompasses many areas, including ultrafast quantum processes, quantum information processing, quantum foundations, and quantum biophysics.

The Centre hosts a node of the Australian Research Council’s Centre for Quantum Computation and Communication Technology and is also home to the Australian Attosecond Science Facility, the only laboratory in Australia where atoms, molecules and materials can be probed on sub-femtosecond timescales.

ABOUT QUANTUM PHYSICS

The physics of quantum systems is an area of intense research activity globally. Quantum systems are composed of microscopic particles such as photons, electrons and atoms. What makes them fascinating, and technologically useful, is their unique behaviour: they defy the principles of physics that govern the more familiar behaviour of macroscopic systems. For example, a quantum particle can behave as if it is in two places at the same time, a phenomenon called “superposition.” Also, two quantum particles that have interacted in the past can be “entangled,” exhibiting correlated behaviour that is impossible in the everyday world. Moreover, these correlations persist no matter how far apart they are, a phenomenon which Einstein called “spooky.” We aim to understand such quantum behaviour better, to develop new ways of controlling it, and to apply it to future technologies. These technologies range from the quantum internet (using entanglement to teleport information encoded in quantum particles) to table-top particle therapy (using lasers to accelerate quantum particles to high velocities with applications in cancer treatment).

Grants and achievements

From 2012–2015, our researchers gained more than $8 million in external funding from national competitive grants and industry money at a ratio of about 2:1. In the last Excellence in Research Australia (ERA) round, in 2015, Griffith received the highest rating (5) in the physical sciences and in quantum physics—an achievement matched by only six Australian universities.

Our research achievements are well known in Australia and internationally, including:

  • world-first experimental work, such as imaging the shadow of a single atom
  • theoretical proposals, such as the ‘many interacting worlds’ approach to quantum mechanics and the quantum origin of the arrow of time.

The Centre has also produced dozens of papers in Nature and Science, and their respective families of journals, including one (Nature, 2007) which has more than 200 citations and was reproduced in Nature Milestones: Photons (2010).

Our facilities

Our state-of-the-art facilities include:

  • Australian Attosecond Science Facility—the country’s premier ultrafast and intense-field laser facility includes two high-power few-cycle Titanium: Sapphire lasers. These lasers serve as a flash for Australia’s fastest camera—the Reaction Microscope.
  • Cold Target Recoil Ion Momentum Spectrometer, also known as ‘Reaction Microscope’ is the only such device in the Southern Hemisphere. It allows momentum-resolved detection of all charged reaction fragments. It integrates a supersonic molecular gas jet and an atomic hydrogen source. In conjunction with Australian Attosecond Science Facility lasers and a pump-probe setup, it is capable of highest temporal resolution measurements of ultrafast atomic and molecular dynamics.
  • Fabrication facilities, including waveguide fabrication, e-beam lithography and 3D laser lithography.
  • Ultrahigh resolution vacuum ultraviolet-visible-near IR spectrometer.
  • World-best single photon detectors, from the National Institute of Standards and Technology.
