Queensland opens Australia's first quantum testbed

The University of Queensland has opened Australia's first open-access quantum testbed, a $10.8 million facility in Queensland.

The National Quantum Computing Testbed is designed to give companies, start-ups and researchers access to quantum hardware for early-stage testing. It aims to address a lack of available hardware that has limited development work in the sector.

Now operating at the university, the testbed is a five-qubit quantum computer built on a superconducting platform. The system can be expanded later, but its current set-up is intended for proof-of-concept work rather than large-scale computing tasks.

Qubits are the basic units of information in quantum computing, broadly equivalent to bits in conventional computers. At the new facility, the processors sit on a gold-plated frame and are cooled to minus 273 degrees Celsius by two dilution refrigerators to shield them from electrical noise.

Professor Arkady Fedorov, who leads the project at the university, said the testbed is intended to lower the cost and complexity of trying out new ideas on real hardware. The set-up is designed to sit between laboratory research and the use of larger quantum machines.

"This testbed will give independent developers and researchers affordable access to cutting-edge quantum hardware for early-stage testing of their ideas," said Professor Arkady Fedorov, Project Lead, The University of Queensland.

He said the small-scale processors would provide a practical way to test technologies before moving to larger systems.

"Its small-scale processors will test new technologies before they're ready to use large-scale quantum hardware, helping to bridge the gap between early-stage development and commercial innovation.

"Lowering a barrier to proof-of-concept testing in quantum research puts Australia on the front foot for quantum hardware development and ensures our people are building valuable skills for the future," said Professor Fedorov.

State backing

The Queensland Government funded the facility through its Quantum and Advanced Technologies Commercialisation Infrastructure Program. The project was also built in partnership with CSIRO, QuantWare, Rohde & Schwarz and Zurich Instruments.

The opening comes as governments and universities in Australia seek to build local expertise in quantum computing and related technologies. Access to hardware remains a central issue for smaller companies and independent researchers, who often rely on overseas systems or limited institutional arrangements to test designs and software.

Andrew Powell, Queensland Minister for Science and Innovation, linked the project to the state's broader economic and technology agenda.

"Queensland innovation and science is among the best in the world, and facilities like the National Quantum Computing Testbed are helping position our state as a leader in this rapidly emerging field," said Andrew Powell, Minister for Science and Innovation, Queensland Government.

"Quantum technology is creating new opportunities for industry, entrepreneurs and researchers, and investments like this help drive local innovation, economic growth and jobs of the future here in Queensland," said Mr Powell.

Research base

The new testbed adds to the university's existing quantum research work. The institution hosts the ARC Centre of Excellence in Quantum Biotechnology, leads Quantum Australia's Queensland node with Griffith University, and has also led the ARC Centre of Excellence for Engineered Quantum Systems.

That research footprint has helped make Queensland one of Australia's main centres for quantum science, spanning biotechnology, computing and engineering. The testbed adds a piece of shared infrastructure with a more direct industry focus.

For technology start-ups and research teams, access to even a small quantum machine can be significant because it allows them to validate hardware concepts, control methods and software ideas before seeking larger funding or more advanced access. In practice, that can shorten the path from theory to demonstration, particularly in a field where experimental time on physical systems is scarce.

The emphasis on open access also marks a departure from the more closed arrangements that often surround specialist research infrastructure. By making the machine available beyond a narrow internal group, the university is seeking to widen the pool of developers and researchers able to work directly with superconducting quantum processors.

The facility's superconducting platform places it within one of the best-known approaches to quantum computing, used by several global groups pursuing fault-tolerant systems. While the five-qubit scale is modest, its significance lies in availability and hands-on testing rather than processing size alone.

That access is likely to matter most for teams at the earliest stage of development, where proving that an idea works on physical hardware can determine whether a project attracts backing. The university said the new machine is open for business.
