Quantum clocks successfully trialled in Washington D.C
Two optical quantum clocks developed by the Precision Measurement Group at the University of Adelaide, led by Prof Andre Luiten in collaboration with the Defence Science and Technology Group (DSTG), were recently sent to Washington D.C. for a six-week field trial as part of AUKUS Pillar II.
The trials, which also included two clocks from QuantX Labs, demonstrated performance beyond traditional GPS-based systems, offering precise and reliable timing and navigation even in contested or GPS-denied environments. While detailed results remain confidential for security reasons, the tests highlight Australia’s growing leadership in quantum technologies.
The trial was attended by Dr Ben Sparkes (DSTG) and Dr Sarah Watzdorf (Precision Measurement Group, IPAS) and was showcased at the Indo Pacific International Maritime Exposition 2025 in Sydney, where Defence Industry Minister Pat Conroy viewed one of the clocks.
Prof Andre Luiten acknowledged the critical support from Defence Trailblazer, saying:
"Great thanks are due to Defence Trailblazer – we wouldn’t have been so far along without your critical role. This support goes beyond just financial – you are playing a key role in figuring out how to get university and industry teams working happily and fruitfully together. This is transformational and game-changing. Well done."
This milestone reflects the strength of collaboration between academia, industry, and government, and demonstrates how IPAS’s photonics research is translating into real-world technologies with global impact.
