Key Takeaways:
PsiQuantum is partnering with Linde Engineering to build one of the world’s largest cryogenic plants to support the development of their utility-scale quantum computer.
The facility will cool silicon photonic chips to 4 Kelvin—significantly warmer than traditional qubit systems—enabling more scalable and practical quantum computing infrastructure.
PsiQuantum has announced a partnership with Linde Engineering to construct one of the largest cryogenic plants ever built for quantum computing. This facility will be installed at PsiQuantum’s Brisbane site and will support the development of the world’s first utility-scale quantum computer.
The cryogenic plant is essential for operating PsiQuantum’s silicon photonic chips at ultra-low temperatures, specifically at 4 Kelvin. This temperature is approximately 100 times warmer than that required by traditional matter-based qubits, which need millikelvin temperatures. Operating at this higher temperature allows the use of established cryogenic technologies, facilitating scalability and reducing complexity.
PsiQuantum’s approach leverages photonic qubits, which are less sensitive to heat compared to matter-based qubits. This characteristic enables the construction of scalable quantum systems capable of solving complex problems in fields such as climate modeling, drug discovery, clean energy, and advanced materials.
Linde Engineering, with experience in delivering over 500 cryogenic plants worldwide, will engineer and deliver the cryogenic infrastructure. The collaboration aims to accelerate the realization of practical quantum computing solutions addressing some of society’s most pressing challenges.
