AUKUS Tests QuantX Lab Quantum Clocks to National Security
AUKUS Trial Successfully Tests Australian Quantum Clocks for GPS-Independent Defence Operations
With the completion of prolonged trials in the US of world-class quantum technology clocks produced in Australia, the AUKUS Pillar II collaboration and linked defence capabilities have advanced.
For six weeks, AUKUS partners in Washington, D.C. extensively examined four Australian quantum clocks. The University of Adelaide and QuantX Labs contributed two clocks. Clocks were evaluated for military navigation and communication systems in different climates.
For quantum clock development, the Albanese government invested $2.7 million in AUKUS Pillar Two capabilities. QuantX Labs had previously received about AUD 2.7 million from the Australian Government to manufacture military pocket quantum photonic atomic clocks. Project partners include the Defence Science and Technology Group (DSTG) and independent academic and industry partners.
An edge in pressure
Quantum clocks detect GPS spoofing and jamming, synchronise communication networks, and provide reliable position, navigation, and timing (PNT) when traditional navigation signals are lacking.
By adopting this technology into AUKUS partners' armed forces, the Australian Defence Force (ADF) can perform better in tough GPS-less situations. Modern military systems depend on GPS signals for timing, navigation, and synchronisation, so maintaining these capabilities if GPS is corrupted, falsified, or jammed is crucial.
In denial situations or underground, urban, or underwater operations, defence troops' ability to execute autonomous operations with safe timing and navigation provides a tactical and strategic advantage. Clocks can replace satellite-based timing systems reliably.
Minister for Defence business Hon. Pat Conroy MP says Australian enterprise has led quantum technology. He said that by using emerging technologies and sharing knowledge and expertise, the partners are establishing AUKUS Pillar II capabilities faster than any single country could.
Precision and Australian Tech
Australia is a global leader in quantum technology due to its top quantum researchers and technologists. Australia's proprietary, sovereign quantum clock technology enhances other countries' advanced portable clocks.
Optic atomic clocks use rubidium or ytterbium atoms in low-pressure gas cells probed by lasers to provide ultra-stable time signals. In tests, their precision was “many orders of magnitude” better than normal GPS time signals. In one-second measurements, they are 20–200 times more accurate than international norms.
The Australian partners created novel technology. The University of Adelaide's portable optical atomic clock, the only one going commercial, uses warm Ytterbium vapour. In the meantime, QuantX is employing Rubidium to construct a portable optical atomic clock based on proprietary, patented Australian intellectual property and a two-color, two-photon technology. These independent technologies that use new elements' unique properties in ways that aren't commercialised elsewhere were developed by ongoing government investment through the Defence Science and Technology Group.
Integration and deployment
The 2024 National Defence Strategy and Defence Innovation, Science, and Technology Strategy say quantum technology is crucial to the ADF's future. The successful experiment results will be shared with AUKUS partners to guide future defence actions using quantum clocks.
Clocks are essential to quantum science and sensing initiatives like quantum radar and quantum communications. Military systems like communications, radar, and networked sensors depend on time, therefore enhancing the timing backbone boosts capacity and endurance.
QuantX and the University of Adelaide launched a USD/AUD 13.8 million initiative. This effort aims to progress technologies from prototype to deployable systems by enhancing dependability and reducing SWaP for field and mobile use. QuantX promises a transportable test and measurement system by early 2025.
Banks, telecommunications, and space missions that require precise timing could benefit from these clocks.
Results are good, but significant obstacles require more time and money. Integrate with PNT infrastructures, assure environmental ruggedness (temperature, vibration, and pressure), and scale cost-effectively for wider deployment. The AUKUS study enhances robust time and navigation technologies.
