Quantum Brilliance (QB), a developer of diamond-based quantum technology, has announced the official opening of the Quantum Diamond Foundry in Melbourne, Australia. The facility is positioned as the world’s first commercial facility dedicated to producing quantum-grade synthetic diamond at scale.
The foundry’s mission is to accelerate the design and fabrication of diamond quantum devices by supplying high-performance quantum diamonds at scale. The project received significant government investment, including $18 million in total support from the Allan Labor Government through Breakthrough Victoria and an initial $13 million investment from the Albanese Labor Government‘s National Reconstruction Fund. The combined public investment is intended to boost sovereign manufacturing capability to produce these diamonds locally and ethically.
QB’s technology utilizes stable qubits inside synthetic diamonds that operate at room temperature, which supports reliable performance in everyday or harsh environments, and enables seamless integration into existing infrastructure across computing and sensing applications. Dr. Marcus Doherty, Co-Founder and CTO of Quantum Brilliance, noted that the foundry is moving quantum out of the lab and into products that can be built, shipped, and used in everyday settings.
Applications for the diamond quantum technologies span various high-value sectors, including assured navigation without GPS, acceleration of neuromedicine development, mineral exploration, and integration into renewable-energy infrastructure. The new foundry is intended to strengthen local expertise, support highly skilled jobs, and reinforce Victoria’s position as a world leader in diamond quantum technologies.
