From CSIRAC to Quantum Dreams: Australia’s Quest for Next-Gen Computing

Australia looks back at its historic CSIRAC computer while investing heavily in quantum technology, sparking debate over its relevance alongside AI.

In the late 1940s, Australia built CSIRAC, the country’s inaugural automatic digital computer, a massive device weighing nearly two tonnes and consuming power comparable to a small neighbourhood. Today the machine resides in a Melbourne museum as a symbol of early innovation. Decades later, Australia is channeling a billion-dollar government investment into quantum computing, aiming to create a "useful" machine in Queensland with US-based PsiQuantum, while startups Diraq and Silicon Quantum Computing are being evaluated by the US Defense Advanced Research Projects Agency for viability by 2033.

PsiQuantum’s chief technical director Geoff Pryde showcases photonic chips designed to host up to a million physical qubits, and Silicon Quantum Computing’s CEO Michelle Simmons highlights rapid progress in controlling single-atom electrons. Nonetheless, a federal Liberal MP has criticized the project as a "quantum gamble in chaos," and technology journalist Gideon Lichfield notes that AI’s recent surge has eclipsed quantum hype.

Researchers like Jacob Biamonte caution that quantum-assisted AI remains experimental, suggesting the two fields will complement rather than replace each other. The story underscores Australia’s desire to reclaim a leading role in computing, echoing the pioneering spirit of CSIRAC.
