From basic quantum physics to quantum technology
We focus on addressing the most challenging problems in our understanding of quantum physics and leveraging these insights to build new technologies.
Our activities range from fundamental physics and quantum information science through to technology development and incorporate both atomic and condensed matter systems. Our scientific pursuits are complemented by deep industry engagement and entrepreneurial activities. The Quantum Science Group at Sydney hosts a global research node of the Microsoft Station Q network (led by Prof. Reilly) and has led to the formation of Australia’s first venture-capital backed quantum-tech start-up, Q-CTRL (founded and led by Prof. Biercuk). The research program we have built represents a unique strength of the Quantum Science group at Sydney: a highly-integrated effort of leading researchers in both quantum optical/atomic physics and condensed-matter physics, theory and experiment.
Our aims
The field of quantum science aims to push the boundaries of our understanding of quantum mechanics and to develop powerful new technologies based on the unique properties of quantum systems.
Our group undertakes experimental and theoretical research in quantum science that addresses both aims. We engineer and manipulate complex quantum systems and explore solutions at both the hardware and software levels. We develop a fundamental understanding of quantum systems by incorporating insights from quantum computing, quantum error correction, and all other aspects of quantum information science.
At this time, a variety of technology platforms have demonstrated quantum coherent phenomena. Our experimental research efforts focus on two proven systems: spins in semiconductors and trapped atomic ions. These efforts, while distinct, share complementary control techniques and are unified by platform-independent theoretical research in support of the group’s broad interests in quantum science.
Our theoretical research tackles the `big questions’ in quantum science. Our research program in Quantum Information Theory explores the full spectrum of questions from the foundational, such as ‘How does complex behaviour emerge from simple quantum systems?’ and ‘Is there a physical reality that explains the strange quantum properties like Bell nonlocality?’, to the practical, including ‘How can we harness the exotic properties of quantum physics, such as topological quantum phases and quantum error correcting codes, to design new technologies like quantum computers?’.
Upcoming events
The University of Sydney, in partnership with the Australian Institute of Physics, presents
Dr Danielle Holmes (UNSW)
The Quantum Century: Unlocking the Unlocking the Universe’s Secrets and Shaping our Future.
Quantum Century: Unlocking the Universe’s Secrets and Shaping our Future.
When: 30 July 2025 | 6:00 pm – 7:30pm AEST
Where: Sydney Nanoscience Hub, Lecture Theatre 3003
Cost: Free, but registrations are essential.
About the speaker:
Dr Danielle Holmes is a postdoctoral researcher and lecturer at UNSW and winner of the Australian Institute of Physics’ Women in Physics Lecturer Award 2025.
She makes ‘qubits’ using individual atoms in silicon chips. These qubits are the building blocks of quantum computers, new technology that will revolutionise humanity’s problem-solving abilities.
Danielle is a passionate science outreach communicator and shares her love for quantum physics well beyond the laboratory- having even performed at the Sydney Comedy Festival!
UNSW, in partnership with the Australian Insitute of Physics, presents
Donna Strickland : Laser Jock
Join Donna in conversation with the ABC’s Tegan Taylor, as she shares the early curiosity that fuelled her love of physics, the joy of discovery and how she became a ‘laser jock’.
Donna Strickland: Laser Jock
When: 15 July 2025 | 06:30pm – 07:45pm AEST
Where: Leighton Hall, John Niland Scientia Building, UNSW Kensington
Cost: Free, but registrations are essential.
About the speaker:
In 2018 Donna Strickland became the first woman in over 50 years to win the Nobel Prize in Physics, and only the third woman in history.
While undertaking her PhD Donna developed chirped pulse amplification – a unique way to amplify ultrashort laser pulses. This breakthrough paved not only the way for safer and more precise laser eye surgery but also improved mobile phone technology and is now helping to advance quantum science.
