The United Nations has proclaimed 2025 as the International Year of Quantum Science and Technology. The goal is to recognise “the importance of quantum science and the need for wider awareness of its past and future impact”. But why quantum? Why now?
Quantum science is both complex and weird. It’s not easy to wrap your head around concepts such as entanglement, light existing as both a wave and a particle, or a cat in a box that is both alive and dead (until observed).
The weirdness of quantum mechanics is now being channelled into the construction of the first quantum computers, communication systems and sensors. Further down the road, it could power the next generation of artificial intelligence (AI).
We are in the early stages of an expensive and resource-intensive quantum race among the world’s powers. The competition for quantum leadership is likely to play a major role in shaping Australia’s economic and national security policy for decades to come.
