Defence launches quantum project to secure military timing systems

A new quantum research initiative led by the Defence Science and Technology Group aims to protect Australian military operations when GPS is compromised, according to a statement released by Defence on Monday.

The project, funded by the Australian Army, will focus on developing a ground-to-satellite optical quantum link to enable secure and precise time synchronisation between Defence assets across combat zones.

This technology could provide critical advantages in contested environments where conventional GPS timing signals are degraded or deliberately jammed by adversaries.

“Quantum technology presents unique opportunities for Defence, and we continue to leverage these emerging disruptive technologies to provide a capability edge for our soldiers, sailors and aircrew,” said Chief Defence Scientist Prof Tanya Monro.

The research team will develop two key components for the quantum link: optical ground stations and quantum light sources. To deliver these technologies, DSTG has formed partnerships with researchers from CSIRO, the Australian National University and the University of Western Australia.

The initiative aligns with priorities outlined in the 2024 National Defence Strategy, which emphasised accelerating next-generation capabilities for the Australian Defence Force.

“This collaboration means we are not only contributing to Australia’s Innovation, Science and Technology ecosystem, but also providing a clear pathway from concept to capability for the technology,” Prof Monro said.

Quantum technology is one of six Innovation, Science and Technology priorities identified in Defence’s strategy “Accelerating Asymmetric Advantage – Delivering more, together.”

The project represents a uniquely Australian contribution to quantum research with direct applications for military operations in technology-dominated battlespaces.
