What Quantum Brilliance does

Quantum Brilliance is an Australian-German quantum technology company founded in 2019 that designs, fabricates, and manufactures diamond-based quantum processors, sensing systems, and supporting software. Its core technology exploits nitrogen-vacancy (NV) centers in synthetic diamond to create qubits that maintain coherence exceeding 1ms and gate fidelity above 99% at ambient room temperature, eliminating the cryogenic cooling infrastructure required by competing superconducting and trapped-ion platforms. The vertically integrated stack spans quantum-grade diamond growth, atomic-scale fabrication via hydrogen depassivation lithography, the proprietary multi-layer 'Smart Diamond' chip architecture, and a Quantum System in Package (QSiP) that integrates microelectronics and photonics for chip-level quantum control. The 'Quoll' room-temperature microprocessor (named one of TIME's Best Inventions of 2025) and the Quantum Development Kit (QDK) product line are deployed at reference customers including Oak Ridge National Laboratory, Pawsey Supercomputing Centre, and Fraunhofer IAF; quantum magnetometers and vector navigation products address defense, autonomous systems, and PNT applications.

The company monetizes through direct enterprise sales of high-value QDK hardware systems, quantum sensing products, and commercial licensing around its open-source Qristal SDK, supplemented by professional services for HPC integration. It pursues a vertical go-to-market spanning HPC and data centers, materials science and drug discovery, defense and intelligence, autonomous systems, position/navigation/timing, power and energy, healthcare, and space/aerospace, with dedicated regional leadership in Australia, Germany, and Japan. Manufacturing is anchored by the newly opened Melbourne Quantum Diamond Foundry (November 2025), supported by more than A$31M in Victoria and federal government investment and A$23M from the National Reconstruction Fund Corporation and Breakthrough Victoria.

Quantum Brilliance has raised approximately A$50M+ to date across seed (2021), Series A (2023), and 2024–2025 strategic rounds involving Main Sequence, NRFC, Breakthrough Victoria, IQT, Altium Capital, and others. The senior leadership team combines deep diamond-NV research expertise (CTO Marcus Doherty; founders from Stuttgart and ANU) with commercial semiconductor and quantum-industry experience (Independent Board Chair Brian Wong; Co-CEO Mark Mattingley-Scott ex-IBM Quantum). The strategic positioning — sovereign-aligned, room-temperature, mass-manufacturable quantum — differentiates the company from capital-intensive dilution-refrigerator peers and supports a long-term thesis of distributed quantum compute at chip scale.
