Quantum technology could become a major force multiplier for Australia’s future defence capabilities, according to Kendy Hau, head of defence at Fujitsu Australia, and Mahesh Krishnan, chief technology officer for Australia and New Zealand at Fujitsu Australia.

Quantum technology could become a major force multiplier for Australia’s future defence capabilities, according to Kendy Hau, head of defence at Fujitsu Australia, and Mahesh Krishnan, chief technology officer for Australia and New Zealand at Fujitsu Australia.

Quantum technology spans three key areas: quantum sensing, quantum communications, and quantum computing, each at different stages of maturity and offering distinct opportunities for Defence.

For Defence, the opportunity extends beyond quantum computing itself. Quantum-inspired technologies are already available and can help solve complex optimisation problems, while future quantum systems could work alongside high-performance computing and artificial intelligence.

The combination could fundamentally accelerate military decision making by rapidly analysing multiple possible outcomes and identifying optimal solutions across sensing, targeting, and command.

Australia’s key challenge is treating quantum as an emerging defence capability rather than simply a research program. The nation has a strong research base and growing industrial partnerships, but the window to translate that advantage into sovereign capability is narrowing.

The message for Defence and industry is clear: Australia cannot afford to wait for fault-tolerant quantum computing before acting. Quantum sensing, communications and quantum-inspired technologies provide opportunities to begin building capability now.

History does not record which side had the better research program. It records which side recognised the disruptive moment and moved faster.
