PsiQuantum Breaks Ground in Queensland

PsiQuantum has begun construction of its quantum computing facility at Moreton Bay Central in Queensland, Australia, marking a significant milestone in the company’s effort to build what it describes as the world’s first utility-scale, fault-tolerant quantum computer. Government officials from Australia and Queensland joined PsiQuantum CEO Victor Peng and co-founder Jeremy O’Brien at the groundbreaking ceremony. The site will eventually house tens of thousands of photonic quantum chips interconnected through optical fiber and supported by one of the largest cryogenic systems ever deployed for quantum computing.

The project represents a major step in PsiQuantum’s photonics-based approach to quantum computing. Unlike companies pursuing superconducting or trapped-ion architectures, PsiQuantum uses silicon photonic chips manufactured with semiconductor industry processes. The Moreton Bay facility will be built in phases, beginning with infrastructure preparation for a large cryoplant being supplied by Linde Engineering. The cryogenic system, ordered in late 2024, is scheduled for delivery in the second half of 2027 and will support the cooling requirements of the quantum computing system. Following installation and commissioning, PsiQuantum plans to deploy cryogenic cabinets filled with photonic quantum chips networked together using conventional optical fiber.

The facility follows the opening of PsiQuantum’s Test and Validation Lab at Griffith University in May 2026 and is expected to create highly skilled jobs across engineering, manufacturing, technical operations, research, and professional services. Located within the Moreton Bay Central Innovation Precinct, the site sits alongside the University of the Sunshine Coast and a TAFE Centre of Excellence, creating a regional ecosystem focused on quantum technologies and advanced manufacturing.

• PsiQuantum broke ground on its utility-scale quantum computing facility in Moreton Bay, Queensland.

• The system will use photonic quantum computing technology based on silicon photonic chips.

• The facility will ultimately house tens of thousands of photonic quantum chips connected via optical fiber.

• A large-scale cryoplant supplied by Linde Engineering is scheduled for delivery in 2027.

• The project follows the opening of PsiQuantum’s Brisbane Test and Validation Lab in May 2026.

• The site is expected to support workforce development and advanced manufacturing initiatives in Queensland.

“Building a quantum computer that solves real world problems is one of the great engineering challenges of our time. For decades, quantum computing has held the promise of transforming what humanity can achieve through computation, and today in Australia we are beginning to turn that promise into reality,” said Victor Peng, CEO of PsiQuantum.

🌐 Analysis: PsiQuantum’s strategy differs from many competitors because it leverages semiconductor manufacturing techniques and optical networking technologies already deployed at scale. The company’s emphasis on utility-scale systems reflects a growing industry shift away from small quantum processor milestones toward fault-tolerant architectures capable of supporting practical applications.

🌐 Analysis: PsiQuantum has attracted substantial backing from governments in both Australia and the United States as it advances its photonic approach. The company competes with organizations including IBM, Google, IonQ, Quantinuum, and Rigetti Computing, each pursuing different hardware architectures. By combining photonic chips, optical networking, and large-scale cryogenic infrastructure, PsiQuantum is positioning itself to build a quantum system more akin to a data center than a traditional laboratory instrument.
