Australia's Quantum Roadmap: PsiQuantum Brisbane and Silicon Quantum Computing's Quantum Resistant Bet
The National Strategy
Australia's National Quantum Strategy, published May 2023 by the Department of Industry, Science and Resources, commits an ~$1 billion AUD target investment with long-range goals of 19,400 quantum-related jobs and a $6 billion industry by 2045. The centerpiece commitment came later: the PsiQuantum Brisbane deal in April 2024.
PsiQuantum Brisbane Deal
In April 2024 the Australian federal government and the Queensland state government committed a combined $940 million AUD ($470 million federal, $470 million state) to support PsiQuantum's buildout of a photonic quantum computing facility in Brisbane. The target: utility-scale photonic quantum computing operational by end of 2027.
This is the largest public quantum hardware commitment per capita of any country. It is also the most controversial; shadow minister Paul Fletcher questioned the selection process transparency. PsiQuantum's stated aspiration of roughly 1 million physical qubits remains a company projection, not a peer-reviewed milestone.
Silicon Quantum Computing (SQC)
Founded 2017 in Sydney, led by Scientia Professor Michelle Simmons at UNSW. SQC builds silicon-based atom spin qubits. Initial $83 million from Australian government, NSW state, UNSW, Commonwealth Bank, and Telstra. SQC demonstrated the first two-qubit atom-based gate in silicon.
Five Eyes Coordination
Australia's Signals Directorate (ASD) coordinates PQC with US NSA, UK NCSC, Canadian CSE, and New Zealand GCSB via the Five Eyes alliance. This means Australian classified PQC migration aligns closely with NSA CNSA 2.0 deadlines.
Implications
- Australian banking (APRA), telecom (ACCC), and government IT align with NIST FIPS 203/204/205 on Five Eyes timelines.
- The Brisbane deal places a CRQC-capable photonic facility in allied territory if PsiQuantum's aspiration is achieved.
- Australian public cloud providers deploy hybrid ML-KEM following the pattern of AWS, Google Cloud, and Azure in parent jurisdictions.
Frequently Asked Questions
What is the PsiQuantum Brisbane deal?
A $940 million AUD combined federal and Queensland state commitment to PsiQuantum, announced April 2024. Targets utility-scale photonic quantum computing operational in Brisbane by end of 2027.
Is PsiQuantum's 1 million qubit goal verified?
No. It is a company aspiration, not a peer-reviewed milestone. Achieving it would require significant breakthroughs in photonic qubit fidelity, interconnect, and error correction beyond the current state of the art.
Who is Michelle Simmons?
Scientia Professor Michelle Simmons of UNSW, founder of Silicon Quantum Computing (SQC). Her lab demonstrated the first two-qubit atom-based gate in silicon. She is among the world's most cited atom-qubit researchers.
Is Australia aligned with NSA CNSA 2.0?
Via Five Eyes coordination, yes. Australian defense and intelligence systems follow CNSA 2.0-aligned timelines, and commercial adoption follows NIST FIPS 203/204/205.
