Insider Brief
Commonwealth Scientific and Industrial Research Organisation (CSIRO) has developed portable quantum light sources designed to support secure time transfer by detecting interference with satellite-based navigation signals.
The devices generate entangled photon pairs that could help provide alternative timing capabilities in environments where GNSS signals are disrupted by jamming or spoofing.
The project, developed with Australia’s Defence Science and Technology Group, aims to support secure communications and timing applications across defence and civilian infrastructure.
