The future of navigation may rely not on satellites however on sub-atomic particles.

Defence scientists are engaged on cutting-edge quantum applied sciences that would in the future present the Navy with extremely safe, satellite-independent navigation and timing methods.
Looking for a way to keep away from the menace of Global Positioning System (GPS) sign interference provides Nicole Blaess a transparent sense of function.
“What I love about quantum is the mystery around it,” Mrs Blaess mentioned. “Every day that I come into work, working in the lab, solving a piece of the puzzle, brings us closer to finding a solution that helps improve the safety of our warfighters.”
Mrs Blaess works on quantum-secured time switch, a way of sending ultra-precise timing indicators utilizing packets of mild that — because of quantum entanglement and the legal guidelines of quantum mechanics — is inherently safe from interference.
The very act of making an attempt to measure entangled particles instantly disturbs the quantum state, that means ships at sea might use this know-how to detect inconsistencies of their navigation knowledge.
“One of my big motivators is to translate really obscure science, like quantum mechanics, and build technologies people use and benefit from,” Mrs Blaess mentioned. “That’s what I really love about STEM.”
Defence scientist Ben Sparkes mentioned quantum was a captivating subject to work in, with many alternatives to construct a rewarding profession, because the know-how is quickly transferring from the lab to real-world functions.
“We’ve got quantum-sensing and quantum-computing companies that need people to work for them; quantum-skilled professionals to come and develop that technology of the future,” Dr Sparkes mentioned.
One such know-how is the quantum clock, which makes use of the motion of atoms to measure time extraordinarily exactly, and will doubtlessly type the idea of a self-contained navigation system.
When paired with knowledge from movement sensors that monitor a vessel’s route and pace, this info might permit ships to find out their place with out counting on GPS.
Defence Science and Technology Group is concentrated on transferring these improvements from lab-based experiments to sturdy, moveable methods appropriate to be used by the Australian Defence Force.
“We work with key experts in quantum technology around the country, and they do amazing work,” Dr Sparkes mentioned.
“Australia really punches above its weight in terms of impact for quantum science compared to the rest of the world.”
Defence is celebrating National Science Week from August 9-17. This yr’s theme is ‘Decoding the Universe – Exploring the unknown with nature’s hidden language’.
The United Nations has named 2025 because the International Year of Quantum Science and Technology, marking 100 years because the delivery of quantum mechanics and the beginning of a revolution in physics.
