Deteqt, an Australian deep tech company building one of the world's most compact quantum magnetic sensors, has closed a A$5 million ($3.6 million) seed round led by Main Sequence, with participation from ATP Fund, BOKA Capital, Beaten Zone Venture Partners, Uniseed, and the University of Sydney.
Deteqt's breakthrough is a chip-scale quantum magnetometer: an exquisitely sensitive sensor that combines a diamond crystal with a custom semiconductor chip, compact enough to be embedded in drones, autonomous vehicles and robots.
“Our technology uses engineered diamond to measure magnetic fields with extremely high sensitivity,” said Dr Jim Rabeau, CEO and co-founder of Deteqt. “The diamond contains atomic-scale quantum defects that respond to magnetic fields. When illuminated with laser light, they emit an optical signal that changes depending on the surrounding magnetic environment, allowing the system to measure magnetic fields precisely. Deteqt’s focus is on integrating this capability into a compact semiconductor platform suitable for scalable manufacturing.”
Rabeau says magnetic fields permeate every object, every geological formation, every living body. "When we have been able to access these signals at all, the results have been profound - MRI, mineral exploration, brain imaging. But these are isolated breakthroughs, built on systems too large and expensive
