Introducing Quantinuum: The World's Largest Integrated Quantum Computing Company

• Quantinuum and The University of Western Australia (UWA) sign MOU to help prepare Australia’s workforce and innovation ecosystem for the hybrid quantum-AI-HPC computing era
• Quantinuum will provide UWA-affiliated researchers, students and entrepreneurs with access to its full-stack quantum computing ecosystem, including Helios, the world's most accurate commercial quantum computer¹
• Collaboration will focus on developing quantum applications for sectors critical to Australia's economy, including critical minerals, energy, agriculture, and healthcare

BROOMFIELD, Colo., and PERTH, Australia—October 5, 2026—Quantinuum (NASDAQ: QNT), a leading quantum computing company, today announced the signing of a Memorandum of Understanding (MOU) with The University of Western Australia (UWA) to advance Australia’s quantum capability by expanding access to advanced quantum computing, developing quantum talent, and accelerating the development of practical applications that integrate quantum computing, AI, and high-performance computing (HPC).

Through the collaboration, UWA-affiliated researchers, students, and entrepreneurs will gain cloud-based access to Quantinuum's full-stack quantum computing platform, including Helios, the company's latest-generation quantum computer. The partnership is designed to provide hands-on experience with advanced quantum technologies while creating new opportunities to explore how quantum computing, artificial intelligence, and high-performance computing can work together to address complex real-world challenges.

The organisations will also explore opportunities to expand UWA's Quantum and AI research ecosystem through a university-wide quantum computing applications centre that would bring together academic, industry, and government stakeholders to identify and develop high-value use cases in critical sectors for Australia’s economy, including critical minerals, energy, agriculture, and healthcare.

"Australia has set an ambitious vision for quantum, and it is making meaningful progress toward turning that vision into reality thanks to leadership from institutions like UWA," said Marvin Lee, Quantinuum’s Singapore-based Country Leader. "Together, we're bringing our full suite of capabilities, from world-leading hardware and software to application expertise and ecosystem programs, to develop practical quantum applications and hybrid workflows that will prepare Australia for the quantum era and support the nation's future prosperity."

Beyond providing access to advanced quantum systems, the partnership aims to help build the technical capabilities and innovation networks needed to support Australia's long-term quantum ambitions. Through engagement with Quantinuum programs such as Q-Net and the Startup Partner Program, researchers, developers, and entrepreneurs will have opportunities to access training, collaborate with peers across the global quantum ecosystem, and accelerate the development of quantum-enabled solutions.

Working alongside UWA researchers and industry stakeholders, Quantinuum experts will help evaluate candidate use cases, establish technical benchmarks and assess hybrid workflows that integrate quantum computing, artificial intelligence, and high-performance computing.

Professor Jingbo Wang, founder and Director of UWA’s Research Centre for Quantum Information, Simulation and Algorithm (QUISA), said the partnership built on UWA’s strengths in quantum computing research.

“Through co-design with potential end users and quantum computing hardware providers, this initiative will create new opportunities for UWA researchers, students and industry partners, while strengthening interdisciplinary collaboration across the University. We look forward to exploring all the opportunities this will bring for our researchers as well as student pathways, internships and workforce training initiatives,” Professor Wang said.

“Access to leading quantum technologies helps Australian researchers, students and companies build capability and understand where quantum can deliver real value,” said Petra Andrén, CEO of Quantum Australia. “Collaborations like this create opportunities to develop skills, test applications and connect research with industry challenges. Australia has strengths across the quantum technology stack. Access to the best capabilities, both here and internationally, will help translate those strengths into economic and community benefit.”

The partnership reflects a shared commitment to ensuring Australia remains not only a source of quantum discovery, but a place where quantum technologies are put to work solving real-world challenges and creating economic value.

• The federal funding supports critical R&D and U.S. quantum semiconductor manufacturing capabilities needed to scale fault-tolerant trapped-ion quantum computing.
• Company partnering with GlobalFoundries to fabricate next-gen ion traps and control electronics, and Monarch Quantum to develop and manufacture reliable lasers and optical components.

Washington, D.C. – September 8, 2026 – Quantinuum (Nasdaq: QNT), a leading quantum computing company, today announced it has finalized an agreement with the U.S. Department of Commerce’s CHIPS Research and Development Office for $100 million in federal funding deployed through the CHIPS and Science Act. The award, which follows a letter of intent announced in May, supports R&D and U.S. quantum semiconductor manufacturing capabilities needed to deploy large-scale, fault-tolerant trapped-ion quantum computers.

Quantinuum, which was the only company with a trapped-ion based architecture to be awarded CHIPS R&D funding, develops the world’s most accurate commercial¹ computers with industry-leading error correction fidelity.²  The company leverages established semiconductor manufacturing processes to help ensure reliability, repeatability, and scalability of the company’s current and future quantum computers.

“This award is a validation of Quantinuum’s leadership in trapped-ion quantum computing," said Dr. Rajeeb Hazra, President and CEO of Quantinuum. “Together with our domestic partners, we are building the technology and supply-chain foundation needed to scale fault-tolerant systems and strengthen America's leadership in this strategically important field.”        

The award will support R&D that the company expects to help strengthen and diversify its supply chain, adding onshore partners GlobalFoundries and Monarch Quantum. GlobalFoundries will be one of several of Quantinuum’s foundries enlisted to fabricate its next-generation ion traps and other electronics, specifically focused on using 300mm wafer technology; Monarch Quantum plans to develop and manufacture scalable, reliable lasers and optical components required for Quantinuum’s trapped-ion systems.

“As quantum computing moves closer to commercial scale, manufacturing will be critical to unlocking its full potential,” said Tim Breen, CEO of GlobalFoundries. “GlobalFoundries is proud to partner with Quantinuum to help scale their trapped-ion technology. By bringing our expertise in high-volume, differentiated semiconductor manufacturing, we're helping create a path to more scalable, reliable quantum hardware and advancing the next generation of American innovation.”

“The road to large-scale, trapped-ion quantum computers relies on moving away from complex, sprawling optical setups to scalable, reliable integrated photonics engines," said Dr. Timothy Day, CEO of Monarch Quantum. "We are honored to expand our partnership with Quantinuum to advance their hardware roadmap and to help strengthen U.S. leadership in quantum computing manufacturing and supply chain resilience.”

Together, these efforts are intended to reduce system complexity and improve component robustness, reliability, and reproducibility, ultimately supporting the continued scaling of trapped-ion quantum computers, while strengthening domestic capability across critical photonics and semiconductor manufacturing.
