Quantum Brilliance Pty Ltd

Quantum Brilliance Pty Ltd says it builds diamond-based quantum chips and products designed to work at room temperature. The company describes a vertically integrated stack spanning quantum-grade diamond, nitrogen-vacancy engineering, device architectures, and deployable sensing and computing products. Its technology is based on diamond NV centers and a multi-layered “smart diamond” chip that can be configured for either sensing or computing.

The company states it was founded in 2019 and focuses on compact, manufacturable quantum technology that integrates with existing infrastructure, including CPUs and GPUs. Its website lists applications across sensing and computing, including datacenter and HPC, materials R&D, healthcare, autonomy, PNT, space, and situational awareness. The site also states that a room-temperature quantum computer was deployed at Pawsey Supercomputing Research Centre in 2022 and that a cluster of three room-temperature quantum computers was deployed at Oak Ridge National Laboratory in 2025.
