Unveiling the first fully integrated and complete Quantum Monte Carlo Integration Engine

• Completed upgrade of Quantinuum’s Reimei quantum computer to its H2 system establishes RIKEN’s hybrid quantum-supercomputing platform as the most capable of its kind in the world and creates a pathway to expand research across electronics, energy and life sciences.
• Quantinuum and RIKEN will build upon this pioneering computing architecture to develop a fault-tolerant “Made with Japan” quantum computer to extend Japan’s long-term quantum leadership.
• To further accelerate commercial adoption of quantum-AI hybrid supercomputing in Japan, the partners will collaborate with SoftBank Corp. to develop a path to connect quantum computers directly with AI data centers.

TOKYO — November 10, 2026 — Quantinuum (NASDAQ: QNT), a leading full-stack quantum computing company, and RIKEN, Japan’s leading national comprehensive research institute, today announced an expanded partnership to advance quantum-AI hybrid supercomputing in Japan. Following a significant upgrade to Quantinuum’s Reimei quantum computer at RIKEN, the partners will pursue more advanced scientific and industrial applications, work with Japanese universities and suppliers toward the development of a “Made with Japan” fault-tolerant quantum computer, and collaborate with SoftBank Corp. to explore the connection of quantum computer with AI data centers in Japan.

Quantinuum’s quantum computer, Reimei, installed at RIKEN, has successfully completed its upgrade to System Model H2. Reimei is operated as part of the JHPC-quantum project, funded by NEDO. This upgrade further enhances the capabilities of the project's quantum–HPC hybrid computing platform and enables researchers to investigate more complex quantum systems that are increasingly difficult to simulate using classical computing alone, broadening the scientific problems they can explore.

Quantinuum and RIKEN will use the upgraded platform to combine quantum computing, supercomputing and AI in support of use case development across electronics, energy and life sciences. Building on their years-long collaboration, the partners will also draw on their experience integrating and operating Reimei to inform the development of a fault-tolerant “Made with Japan” quantum computer.

“Japan’s quantum ambitions require advanced capabilities today and a sustained commitment to developing what comes next,” said Dr. Rajeeb Hazra, Quantinuum CEO. “The upgrade to Reimei expands what we can explore with RIKEN across electronics, energy and life sciences. Together, we are building on this work to develop a fault-tolerant quantum computer with Japanese universities and suppliers, while exploring with SoftBank how these capabilities can become accessible to industry through Japan’s AI data centers.”

Two research projects that have begun operations on Reimei before the public launch of its services illustrate how Quantinuum and RIKEN are leveraging the hybrid platforms upgraded capabilities to push the frontiers of scientific discovery:

• Quantum-AI for materials simulation: The partners are using RIKEN’s JHPC-quantum GPU supercomputer, ROQUO, to train an AI model on Reimei-generated quantum data for magnetism simulations. Preliminary results suggest the model can make more accurate predictions than AI models trained on classical simulations alone and more precise predictions than the quantum computer itself. Understanding magnetism at the atomic level could inform the development of materials for next-generation technologies such as ultra-high-field MRI and smart power grids.
• Quantum-AI for biomolecular simulation: The partners are combining Reimei, RIKEN’s Fugaku supercomputer, and NVIDIA’s evolutionary AI agent running on ROQUO to simulate a complex photoactive biomolecule, targeting unprecedented scale and detail. Better understanding of how biomolecules respond to light could inform the design of more efficient solar cells among other industrial opportunities that could arise from advances in biomolecular engineering.

This research supports RIKEN’s AI for Science initiative and aligns with U.S.-Japan efforts to advance AI-driven discovery, including a planned $1 billion partnership under the U.S. Genesis Mission.

“With the upgraded Reimei quantum computer, we will be able to tackle more complex and larger-scale scientific problems that were difficult to address with the previous H1 system, further advancing quantum–HPC hybrid computing through our ongoing JHPC-quantum project,” said Dr. Mitsuhisa Sato, Division Director, Quantum-HPC Hybrid Platform Division, RIKEN Center for Computational Science (R-CCS). “Furthermore, the newly signed Memorandum of Understanding will pave the way for expanding our research into the use of quantum computing for AI for Science, a key initiative being promoted by RIKEN.”

The partners’ joint research and development toward a “Made with Japan” fault-tolerant quantum computer will involve Japanese universities and domestic components suppliers. This “Made with Japan” effort will combine Quantinuum’s quantum technology with domestic research and manufacturing expertise, drawing on lessons from integrating and operating Reimei at RIKEN.

Under a separate agreement, Quantinuum, RIKEN and SoftBank will explore how quantum computing can be connected directly with AI data centers in Japan. The partners will assess infrastructure readiness and examine how connected systems could support commercial quantum-AI hybrid computing services, broadening access beyond the research community.

“Japan has established a strong foundation for hybrid quantum-HPC computing through the NEDO-supported JHPC-quantum project,” said Takenori Kobayashi, Vice President, Head of Product Research & Development Division at SoftBank Corp. “Our responsibility is to turn these achievements into industrial value. Together with RIKEN and Quantinuum, we aim to advance a Quantum AI Datacenter that connects quantum computing with AI and HPC, making these capabilities accessible to businesses across Japan.”

Non-GAAP Financial Measures

To supplement Quantinuum’s condensed consolidated financial statements presented in accordance with U.S. generally accepted accounting principles (“GAAP”), the Company uses the following non-GAAP financial measures presented in this release: Adjusted Gross Profit, Adjusted Gross Margin, Adjusted Net Loss, fully distributed, Adjusted EBITDA, and Adjusted Net Loss Per Share, fully distributed.

Adjusted Gross Profit starts with GAAP gross profit and adds back equity compensation and related employer taxes attributable to cost of revenue and depreciation and amortization attributable to cost of revenue.

Adjusted Gross Margin is calculated as Adjusted Gross Profit divided by revenue, net.

Adjusted Net Loss, fully distributed starts with GAAP net loss on an as-converted basis, adjusts for equity compensation and related employer taxes, costs of the initial public offering and the transition to public company reporting, severance expense, the change in fair value of liability-classified warrants, and loss on disposal and write down of assets, and then applies an assumed statutory tax rate to the resulting adjusted pre-tax loss. No tax benefit is recognized in respect of losses subject to a full valuation allowance, and accordingly no tax benefit is reflected in the periods presented.

Adjusted EBITDA starts with Adjusted Net Loss, fully distributed, and further excludes income tax expense, interest income, net, depreciation, and amortization of acquired intangibles.

Adjusted Net Loss Per Share, fully distributed is calculated as Adjusted Net Loss, fully distributed, divided by adjusted shares, fully distributed, basic and diluted, comprising weighted-average Class A common shares outstanding and Common Units of Quantinuum Holdings.

Management believes these measures provide investors with additional information useful in evaluating the Company’s operating performance and trends across periods. Quantinuum’s results include large non-cash charges that management does not consider indicative of ongoing operating performance, principally stock-based compensation recognized on completion of the Reorganization and remeasurement of liability-classified warrants. Both are driven by accounting triggers and external inputs rather than operating activity. As an early commercial-stage business, Quantinuum’s period-to-period results also are affected by the timing of individual contracts. Measures that isolate underlying operating performance from non-cash and transition items help investors assess trends across periods.

Quantinuum’s Up-C structure means that GAAP net loss attributable to Quantinuum Inc. reflects only the Class A share of the economics. Presenting adjusted results on an as-converted, fully distributed basis describes the whole economic enterprise, which is how management assesses performance and how the business is managed. Management uses these measures for internal planning and forecasting, evaluating operating performance, and preparing budgets.

These non-GAAP financial measures are supplemental and are not prepared in accordance with GAAP. They are not intended to be considered in isolation or as a substitute for the most directly comparable financial information prepared in accordance with GAAP. Quantinuum’s non-GAAP measures may differ from similarly titled measures used by other companies and, therefore, may not be comparable. Investors should review the reconciliations and should not rely on any single financial measure to evaluate the Company’s business.

Each non-GAAP financial measure is reconciled to its most directly comparable GAAP financial measure in the tables at the end of this release.
