Quantum science research

The discovery of quantum physics opened a realm of amazing phenomena that are still being uncovered and harnessed today. Scientists at ANU are working on all parts of this process – unravelling fundamental quantum processes through to developing quantum devices ready for market.

Solid State Spectroscopy

The Solid-State Spectroscopy group is developing repeater and router hardware to enable the distribution of quantum information over global communication networks. At its heart is a highly innovative linear optics quantum processor design that utilises quantum memories based on rare-earth doped crystals. The lab is working with the German Aerospace Centre (DLR) to scope future satellite missions that will demonstrate the deployment of the processor in a satellite quantum communication network.

Polariton Bose-Einstein Condensation Group

The ANU Polariton BEC group undertakes experimental and theoretical research on hybrid light-matter particles - exciton-polaritons - in semiconductors. Driven by laser light, exciton polaritons coalesce into macroscopically occupied quantum states similar to Bose-Einstein condensates (BECs) of ultracold atomic matter, but at much higher temperatures, closer to ambient conditions. Our research focuses both on fundamental investigations of quantum phase transitions in exciton-polariton systems, and on development of low-energy polariton-based optoelectronic devices.

Metastable Helium Bose-Einstein Condensate

The Metastable Helium BEC laboratory investigates fundamental aspects of quantum mechanics. A BEC is a collection of around a million atoms occupying a single quantum state that can be centimetres in size, allowing quantum effects to be measured on a macroscopic scale. Combined with the unique single atom detection capabilities of metastable helium, this system is used to study effects such as entanglement of massive particles and quantum phase transitions.

Quantum Theory Group

The Quantum Theory Group at the Department of Quantum Science studies systems of atoms and light, analysing fundamental behaviour and designing the next generation of quantum devices. The group pioneers new theoretical tools to model degenerate quantum gases, and creates machine-designed quantum control schemes to invent quantum computing technology and advanced sensors that operate below the standard quantum limit.

Quantum Nano-photonics

We research integrated approaches for creation and manipulation of multi-photon states. We develop waveguide circuits for nonlinear generation of entangled photons with applications in broadband low-light spectroscopy and in monitoring of transmitted photon states. Through the Centre for Transformative Meta-Optical Systems we design and fabricate ultra-thin nano-structured metasurfaces that realize parallel quantum interference for tailored generation, transformation and detection of quantum states of light with applications for communications and imaging.

Spinwave Engineering Lab

Photons of light are an excellent means for transmitting quantum information owing to their high speed. Our research seeks to build a memory capable of catching and releasing quantum states of light for future quantum information networks. We do this by storing light as a “spinwave” in clouds of laser cooled atoms. We also look for ways to engineer the atomic spinwaves and enable new ways of processing quantum information.

Nuclear Quantum Physics

The Heavy Ion Accelerator Facility is Australia’s highest energy ion accelerator and allows us to study quantum phenomena in nuclei. For example, we study quantum tunnelling in nuclear fusion, a crucial step in stars making carbon, and the complex quantum effects involved in creating new elements for the periodic table. The accelerator is also used to study nuclear decays and how they could be used to treat cancer via the Auger effect.

Centres of Excellence

ANU is a partner in four quantum-related Australian Research Council Centres of Excellence

ARC Centre of Excellence for Gravitational Wave Discovery

The mission of the ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav) is to capitalise on the historic first detections of gravitational waves to understand the extreme physics of black holes and warped spacetime, and to inspire the next generation of Australian scientists and engineers through this new window on the Universe.

At ANU we specialise in quantum noise reduction technology – ‘squeezing’ – which we use to enhance the detection of gravitational waves.

ARC Centre of Excellence in Future Low-Energy Electronics Technologies

The ARC Centre of Excellence in Future Low-Energy Electronics Technologies (FLEET) addresses a grand challenge: reducing the energy used in information technology, which now accounts for 8% of the electricity use on Earth, and is doubling every 10 years.

Our research focuses on creating low-energy electronics based on new quantum materials – the current, silicon-based technology (CMOS) will stop becoming more efficient in the next decade as Moore’s law comes to an end.
