What we do
Overcoming key scientific barriers to creating scalable, reliable quantum computers.
Three research pillars. One shared goal.
QPI's research is organised around three interconnected pillars that address the biggest barriers to practical quantum computing.
Pillar 1: High - Performance Qubits
Qubits are the fundamental building blocks of quantum computers. Today, they remain prone to errors, limiting the scale and reliability of quantum technologies.
We are developing the next generation of high - performance qubits by exploring new materials, novel quantum systems and innovative methods for protecting quantum information. By dramatically reducing errors at their source, we aim to create hardware that is more powerful, more reliable and easier to scale.
Pillar 2: Resource - Efficient Logic
Making quantum computers practical requires far more than better hardware. It also demands smarter ways of processing quantum information.
This pillar develops new approaches to quantum error correction, algorithms and logical operations that reduce the enormous computational resources required by current systems. By making quantum computation significantly more efficient, we aim to lower the cost, complexity and energy requirements of future quantum computers.
Pillar 3: Integrated Architectures
Useful quantum computers will require millions of qubits working together seamlessly. Achieving this scale depends on entirely new ways of connecting quantum devices.
Our researchers are developing technologies that link quantum systems within and between devices, enabling modular architectures that can grow far beyond the limits of today's prototypes. These integrated approaches combine the strengths of different quantum technologies to create more capable and flexible computing platforms.
Collaboration drives discovery
The greatest breakthroughs often happen where disciplines intersect.
Each research pillar strengthens the others, creating opportunities for ideas, technologies and discoveries to move rapidly across different areas of expertise.
High-performance quantum hardware (Pillar 1) enables more efficient use of resources, by reducing hardware overheads for quantum error correction (Pillar 2): certain codes may be ineffective at high error rates but become plausible and beneficial if applied to high-quality hardware. Some of the most promising encodings with reduced hardware overheads (Pillar 2) pose heavy demand on connectivity at the physical level, which will be unlocked by the integration research (Pillar 3). Integration of diverse quantum hardware platforms (Pillar 1) and transduction between different degrees of freedom (Pillar 3) allows optimising the hardware for different functions, such as fast-operation qubits vs. long-lived memory qubits.
This collaborative model allows QPI to pursue ambitious, hardware-agnostic research that is focused on solving the fundamental challenges facing quantum computing as a whole.
From discovery to impact
QPI's research is driven by ambitious scientific milestones that build towards technologies capable of solving globally significant problems.
Working alongside industry partners, government agencies and international collaborators, we are creating the scientific foundations that will enable future quantum computers to tackle challenges beyond the reach of today's most powerful classical machines.
By combining world-leading research with a commitment to translation and collaboration, QPI is helping shape the future of quantum computing in Australia and around the world.
