Quantinuum (NASDAQ: QNT) expanded its partnership with RIKEN to advance quantum-AI hybrid supercomputing in Japan following an upgrade to Reimei.
The quantum computer at RIKEN has completed its upgrade to System Model H2. The partners plan to use the upgraded platform for applications in electronics, energy and life sciences, and develop a fault-tolerant “Made with Japan” quantum computer with Japanese universities and domestic suppliers. A newly signed memorandum of understanding covers expanded quantum-computing research for AI for Science.
Under a separate agreement, Quantinuum, RIKEN and SoftBank will explore direct connections between quantum computers and Japanese AI data centers, assessing infrastructure readiness and potential commercial services. Two research projects are already operating on Reimei, studying magnetism and a light-responsive biomolecule; the magnetism results remain preliminary.
Quantinuum (Nasdaq: QNT) will participate in the Cantor Convergence 4th Annual Crypto, FinTech, AI & Energy Infrastructure Conference. The conference takes place November 10–12, 2026, in Miami, Florida. Management will participate in a fireside chat and host one-on-one meetings with investors.
Quantinuum (Nasdaq: QNT) reported third-quarter revenue growth of 233% year over year and raised its full-year 2026 revenue outlook. Revenue reached $9.1 million, versus $2.7 million a year earlier. GAAP net loss widened to $117.851 million from $52.036 million, while adjusted EBITDA loss widened to $80 million from $45 million. GAAP gross margin improved to 33.3% from negative 43.5%.
The company now expects 2026 revenue of $31–$34 million, previously $28–$32 million. Cash and cash equivalents totaled $1.94 billion at September 30. Quantinuum signed its largest cloud agreement, a multi-year extension with a global financial institution providing committed access through Apollo and Nexus. Nexus adoption reached 215 organizations, nearly 20% higher quarter over quarter. The company says Sol remains on track for the second half of 2027 and Apollo for 2029.
Quantinuum (NASDAQ: QNT) unveiled a Nexus development roadmap extending through Apollo, its universal, fully fault-tolerant quantum computer planned for 2029. The company aims to progressively automate application development and deployment as its hardware advances; fault-tolerant computing uses error correction to support reliable calculations.
Nexus supports more than 200 organizations, up 45% in 2026. Job submissions increased tenfold in the 12 months through August 2026 versus the preceding 12-month period. A December release is expected to expand hybrid quantum-classical workflows and add error-correction codes and execution analytics. Quantinuum is also integrating Nexus into Oracle Cloud Infrastructure's environment to support Helios deployment and integration.
Quantinuum (QNT) will release its third-quarter financial results on November 5, 2026, after market close and host a conference call that day. The results cover the quarter ended September 30, 2026. The call begins at 5:00 PM Eastern time and will be webcast live. A replay will remain available on the Quantinuum Investor Relations website for one year.
Quantinuum (NASDAQ: QNT) achieved 99.9995% logical fidelity, a measure of error-corrected accuracy, in a study on its Helios quantum computer. The result equals five errors per million operations. The error rate was 10 times lower than its September 2026 result and 100 times lower than the best published result across other hardware modalities, reported by Google Quantum AI.
The study used a color code, an error-correction method, on the same hardware as the earlier demonstration. Each tested increase in code distance, which determines protection against errors, reduced remaining logical errors by a factor of 12. Quantinuum says accuracy is now within the target range for Apollo, its planned fault-tolerant quantum computer expected by 2029.
Quantinuum (QNT) signed a memorandum of understanding with The University of Western Australia to expand quantum computing access and research collaboration. UWA-affiliated researchers, students and entrepreneurs will receive cloud-based access to Quantinuum's platform, including its Helios quantum computer.
The collaboration aims to develop applications combining quantum computing, artificial intelligence and high-performance computing for critical minerals, energy, agriculture and healthcare. The organisations will explore a university-wide quantum applications centre. Quantinuum experts will help evaluate candidate uses, establish technical benchmarks and assess combined computing workflows. Its Q-Net and Startup Partner Program will offer training and collaboration opportunities.
Quantinuum (QNT)/b) will participate in the Piper Sandler 5th Annual Growth Frontiers Conference, held September 14–16, 2026, in Nashville, Tennessee.Members of the management team will take part in a fireside chat and host one-on-one meetings with investors during the conference.
Quantinuum (QNT) finalized a $100 million CHIPS R&D award with the U.S. Department of Commerce to advance trapped-ion quantum computer manufacturing in the United States.
The federal funding, provided under the CHIPS and Science Act, will support R&D and U.S. quantum semiconductor manufacturing capabilities needed to deploy large-scale, fault-tolerant trapped-ion quantum computers. Quantinuum is described as the only trapped-ion architecture recipient of CHIPS R&D funding and uses established semiconductor processes to enhance reliability and scalability. The company is partnering with GlobalFoundries to fabricate next-generation ion traps and control electronics on 300mm wafers and with Monarch Quantum to develop and manufacture scalable lasers and optical components. These efforts aim to reduce system complexity, improve robustness and reproducibility, and strengthen the domestic quantum hardware supply chain.
Quantinuum (QNT) announced that its management team will participate in the Bernstein 23rd Annual Pan-European Strategic Decisions Conference, held September 9–10, 2026, in London, United Kingdom.
The company will take part in a fireside chat and hold one-on-one meetings with investors during the event.
