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.
Diamond Quantum Science and Technology
The DQST Laboratory studies the physics and applications of optical defects in semiconductors, such as diamond. The Lab’s research covers all domains of quantum science and technology, from the discovery of defects to their incorporation into unprecedented quantum sensors, microscopes, communications and computers. The Lab’s activities span the full spectrum of basic science to commercialisation, and uses methods ranging from ab initio quantum theory through to quantum device design and demonstration.
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.
Electronic Materials Engineering Department
Our research efforts focus on the growth, fabrication and characterisation of III-V semiconductor nanowires and nanostructures for a range of optoelectronic device applications. Through TMOS (ARC Centre of Excellence), we are developing nanoscale laser arrays, advanced and quantum light sources, meta-optics enhanced detectors and nanoscale single photon detectors for applications in augmented reality, LiFi, holographic displays, 3D imaging, IR and quantum remote sensing, and light detection and ranging.
Theory of quantum many-body systems
The Theoretical Physics Department studies the physics and related mathematics of fundamental quantum many-body systems appearing in quantum field theory, condensed matter physics, quantum information theory and quantum light-matter interactions. This field inspires profound developments in mathematics and finds applications in the emerging technology of quantum devices. These application areas include quantum dots in nanotechnology and artificial qubits in superconducting quantum circuits.
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.
Centre for Gravitational Astronomy
CGA explores the science and technology of gravitational wave sources. The centre strategically unifies the ongoing research at Research School of Physics and ANU Research School of Astronomy and Astrophysics.
Active fields of research at CGA span instrumentation, theory, data analysis, source follow-up and multi-messenger astronomy. The centre operates world-class facilities and collaborates with national and international observatories and gravitational wave detectors.
Atomlaser group
The Atomlaser group operates a state-of-the-art quantum sensing program and performs fundamental research into novel non-linear quantum phenomena using mixed species Bose-Einstein condensates (BEC). The group has pioneered BEC-based precision gravity and magnetic sensing and is driving the future of quantum sensing forward with a focus on design for portable systems using cutting-edge lasers, fibre amplifiers and integrated fibreoptic systems.
