About QuantX Labs
QuantX Labs is an Adelaide-based deep-tech company building optical atomic clocks and quantum sensors for precision timing, navigation and positioning. Its clocks use optical rather than microwave frequencies, which the company says makes them 10 to 100 times more stable than existing systems while remaining smaller, portable and more robust. QuantX supplies defence, space and critical-infrastructure customers, having bootstrapped to revenue by selling timing systems to the Australian Department of Defence and deploying its technology on a SpaceX mission.
