Quantum science and technology

The discovery of quantum physics opened a realm of wondrous phenomena which have come to underpin our modern world. Scientists at ANU are part of this new era – unravelling fundamental quantum effects, harnessing them to create the next generation of technologies and bring them to market.

Some of our theoreticians work on the basic formulism of quantum theory, while others apply it to quantum information, many-body systems like nuclei or Bose-Einstein condensates, polariton-excitons, photonics and even quantum gravity.

We are exploring how to use the extreme sensitivity of quantum systems for sensing technology – ranging from sensors of gravity and motion, to electromagnetic fields – to enhancing the detection of gravitational waves, to atomic clocks and quantum microscopy – the imaging of individual atoms.

ANU hosts a comprehensive array of enabling technologies that enable the design of novel quantum materials and technologies. Our large suite of nanofabrication facilities include MOCVD growth systems, diagnostic capabilities and testing facilities, and features one of Australia’s leading nuclear physics establishments, the Heavy-Ion Accelerator Facility.

We are developing quantum computers and the algorithms to run on them, but also land- and space-based quantum network technology and encryption protocols for enhanced security. By integrating these networks and computers we are working to build a quantum internet that stretches across the globe.

We have launched quantum technology start-up companies across all domains of quantum technology: sensing, cryptography, computing and enabling classical technologies. We also have major projects with Defence in precision navigation, gravimetry and secure quantum communications.

We’re partners in four ARC Centres of Excellence, working on developing next generation quantum computing and communication technology (CQC2T), quantum materials, engines and precision imaging systems for quantum machines (EQUS), quantum noise reduction technology, and applying it to gravitational wave astrophysics (OzGrav), and low-energy electronics based on quantum materials (FLEET).

Students at all levels have the chance to engage with our researchers and take part in cutting-edge research, via undergraduate research topics, our selection of Masters programs, through to PhD research.

Potential student research projects

You could be doing your own research into quantum science and technology. Below are some examples of student physics research projects available in RSPE.

Metasurface polarization optics and quantum photonics

This project aims for developing polarization optical devices based on all-dielectric metasurfaces. As no bulky optical elements and moving parts are required, these devices are compact, stable, and can operate in a single-shot mode with high time resolution. Potential applications include sensitive biological imaging and quantum state manipulation and tomography.

Controlling quantum turbulence in atomic superfluids

Turbulence is one of the most important unsolved problems in modern physics, underpinning universal phenomena from galactic formation to heat and pollutant transport in our atmosphere and oceans. This project seeks to theoretically investigate turbulence in superfluids, and introduce methods of controlling the system dynamics using quantum feedback control.

Atom-light interactions in quantum memories

Quantum memories store light in atomic ensembles for applications in quantum computing and networking. This project explores how atoms and light interact in prototype quantum memories that use rare earth atoms in crystals for storage, aiming to improve memory efficiency,  storage capacity, and performance in real-world devices.

How does a quantum system reach equilibrium?

The idea of equilibration is ubiquitous throughout nature. Out-of-equilibrium dynamics – be it caused by a disturbance and subsequent “rethermalisation”, or by passing through a phase transition – is a difficult question to characterise. This project looks at both equilibration and phase transitions in a Bose-Einstein condensate of metastable helium atoms.
