PsiQuantum and Linde Engineering Collaborate to Deliver Cryogenic Plant for World’s First Utility-Scale Quantum Computer in Brisbane
BRISBANE, Queensland, Australia. – PsiQuantum today announced a major milestone in its Brisbane project: a partnership with Linde Engineering to build and deliver one of the largest cryogenic plants ever planned for quantum computing. The plant will be constructed and tested by Linde, then installed at PsiQuantum’s site in Brisbane, where it will provide the cryogenic foundation for the world’s first utility-scale quantum computer.
The cryoplant will support PsiQuantum’s silicon photonic chips, enabling the low temperatures required for fault-tolerant operation at the million-qubit scale—the threshold for solving commercially relevant problems in areas such as climate modeling, drug discovery, clean energy, and advanced materials.
PsiQuantum’s quantum computing system is built around the Omega quantum chip, a manufacturable, silicon photonic platform. Operating these chips at scale requires ultra-low temperatures to suppress decoherence and maintain high-fidelity quantum operations.
“Photons don’t feel to heat the way matter-based qubits do. Our systems can run 100 times warmer – and we appreciate collaborating with a world-class firm like Linde Engineering to deliver industrial-scale systems with proven technology. This is a fundamental scaling advantage and a key reason we are able to move rapidly toward utility-scale quantum computing.”
“We are proud to help PsiQuantum realize their ambitious vision for quantum computing. This collaboration demonstrates how combined expertise can drive advancements in technology and innovation. This technology will help design solutions to address some of the most pressing challenges faced by society today.”
While all large-scale quantum systems must operate in cryogenic environments, most matter-based qubits require millikelvin temperatures—just fractions of a degree above absolute zero. These extreme cooling demands create major obstacles to scaling. PsiQuantum’s photonic qubits, by contrast, will operate at 4 Kelvin, roughly 100 times warmer, enabling the use of established cryogenic technology.
The cryogenic plant will be engineered and delivered by Linde Engineering, with a deep expertise in designing and building ultra-low temperature systems for high-tech industries and scientific research. It has installed over 500 cryogenic plants worldwide, supporting critical applications across semiconductors, fusion research, and and particle physics.
