Quantinuum Reports Third Quarter 2026 Results and Raises Full-Year Revenue Outlook

• Roadmap connects application development and deployment with each generation of Quantinuum hardware through Apollo, its universal, fault-tolerant quantum computer planned for 2029.
• Nexus is designed to be the first developer platform that integrates automated error-correction encoding, execution on Quantinuum hardware, and hybrid workflow orchestration.
• Nexus will progressively handle the complexity of fault-tolerant application development and deploy programs that can scale and grow in capability as hardware advances.

BROOMFIELD, Colo. – November 5, 2026 – Quantinuum (NASDAQ: QNT), the leading full-stack quantum computing company, today unveiled a new roadmap to evolve Quantinuum Nexus, its platform as a service, with the aim of delivering the quantum industry’s first developer platform designed for the fault-tolerant era. The roadmap introduces new capabilities with each generation of hardware through Apollo—the company’s first universal, fully fault-tolerant quantum computer planned for 2029—that further simplify and automate how customers build, deploy, and operate quantum applications.

Since its launch in 2024, Nexus has expanded from managing cloud-based quantum workflows to end-to-end application development and deployment, bringing programming, validation, compilation, and execution into one environment. Nexus provides managed access to the software tools and computing resources customers need for hybrid applications and workflows. Nexus offers flexible access and integration options, both in the cloud and on-premises.

Through 2029, successive releases aim to progressively automate and simplify error correction, resource management, orchestration, and deployment, enabling developers to build and integrate increasingly capable applications at the logical level.

By developing its quantum hardware and software together, Quantinuum helps improve application performance across the entire system and turn hardware advances into capabilities customers can use. Nexus is designed to align those capabilities with each hardware generation, giving customers a simpler development path and Quantinuum a stronger platform for winning and expanding user adoption. Developers can already automatically apply supported error-correction techniques to programs and run them on Helios.

Today, Nexus already supports more than 200 organizations, up 45% in 2026, while total job submissions increased tenfold in the 12 months through August 2026 compared with the preceding 12-month period. This growing engagement establishes a customer and developer base that Quantinuum can continue to grow as its hardware matures.

“Our full-stack approach means each advance in hardware can become a capability customers can build on through Nexus,” said Dr. Rajeeb Hazra, Quantinuum CEO. “Our aim is to build the first developer platform specifically for the fault-tolerant era so customers can start developing applications today and carry that investment forward. Nexus is designed to help them deploy applications and hybrid workflows and integrate the platform into their computing environments. As our systems become more capable, our aim is for the applications, workflows, and expertise customers develop in Nexus to become more valuable, giving them a compelling reason to build with Quantinuum and making Nexus an enduring part of their computing environment.”

Building a Developer Platform for the Fault-Tolerant Era

The Nexus roadmap organizes its capabilities around three stages of the application lifecycle—develop, optimize, and deploy—helping customers build hybrid quantum-classical applications that can advance with successive generations of Quantinuum hardware:

• Develop: The roadmap includes pre-built primitives, fault-tolerant libraries, and domain-specific tools that help developers move from individual quantum circuits to complete applications. The platform will progressively automate error-correction encoding, compilation, and resource management, allowing developers to focus more on the application and less on the underlying hardware complexity.
• Optimize: The roadmap outlines tools to analyze runtime behavior, resource requirements, and application performance. Future releases plan to introduce more error suppression, real-time diagnostics, and increasingly automated error recovery to help customers run larger computations and make more efficient use of quantum resources.
• Deploy: Nexus is being designed to coordinate quantum and classical computing across Quantinuum processors, high-performance computing systems, cloud infrastructure, and third-party tools—helping customers integrate quantum workflows into their existing computing environments and deploy larger fault-tolerant applications.

“Quantum computers are on the brink of achieving fault tolerance at scale. It's exciting: we are entering terra incognita for what we can compute. The new challenge is putting our high-level quantum algorithms into the right form to successfully run on error-corrected hardware. Developer platforms like Nexus help us bridge that gap between quantum algorithm design and deployment,” said José Ignacio Latorre, Director of the Centre for Quantum Technologies, Singapore’s flagship national research center for quantum technology.

Optimized specifically for Quantinuum systems, these capabilities are expected to provide a continuous path from early application development on Helios to increasingly capable implementations on Sol and Apollo to help customers carry their investments forward as the hardware advances.

Building the Foundation Today

Quantinuum is already delivering key elements of this approach. Released in September 2026, Guppy FT and Guppy Algorithms expanded Nexus with supported error-correction schemes, fault-tolerant operations, and composable algorithmic building blocks.

Developers can write programs, automatically encode them for supported error-correction schemes, test them in emulation, and execute supported programs on Helios. Advanced users retain the flexibility to customize architectures for specialized applications.

These capabilities establish the foundation for future roadmap releases, including the upcoming December release which is expected to expand hybrid workflows so that applications can respond to quantum results as they become available. It is also expected to add supported error-correction codes and execution analytics to help developers optimize performance.

Connecting Quantum Applications with Enterprise Computing

Researchers and enterprises are already using Nexus to develop applications across chemistry, materials science, life sciences, and AI, while also integrating Nexus into new environments:

• Qubit Pharmaceuticals and CQT used Nexus to execute quantum Monte Carlo experiments on Quantinuum’s System Model H2 and Helios systems.
• Researchers at RIKEN and the University of Tokyo simulated atomic nuclei on Reimei, using Nexus. They also used Nexus to integrate hybrid quantum-HPC workflows to calculate excited-state energies in a model biomolecular system.
• University of Cambridge researchers used Nexus compilation tools to prepare efficient quantum chemistry circuits while Maastricht University researchers used Nexus to simulate, compile, and run a quantum particle tracking algorithm exploring new approaches to reconstructing particle trajectories.
• Unitary Foundation’s Metriq gym uses Nexus to access Quantinuum hardware for reproducible benchmarking across quantum computing platforms.
• Quantinuum is integrating Nexus into Oracle Cloud Infrastructure’s environment to help support the on-prem deployment and integration of Quantinuum’s Helios computer into OCI’s cloud services offering.

• Quantinuum’s Helios computer achieves a world-record 99.9995% logical fidelity—just five errors in a million operations—using the company’s error-correction architecture.
• Error rate is 10x lower than Quantinuum’s own September 2026 record and 100x lower than the best published result across all other hardware modalities, which was reported by Google Quantum AI using a superconducting system.
• Quantinuum’s successive breakthroughs used different codes on the same hardware, demonstrating how its error-correction architecture and trapped-ion technology drive rapid gains in accuracy, with performance now in the target range for Apollo.

BROOMFIELD, Colo.—October 19, 2026—Quantinuum (NASDAQ: QNT), a leading full-stack quantum computing company, today announced a world-record quantum error-correction result, achieving a logical fidelity of 99.9995% on its Helios commercial computer using the company’s error-correction architecture. This marks Quantinuum’s second breakthrough in two months, demonstrating how its highly accurate trapped-ion hardware and flexible architecture work together to deliver rapid improvements in accuracy.

The achievement reinforces Quantinuum’s error-correction leadership and validates that its accuracy performance is now within the target range for Apollo, the company's planned universal fault-tolerant quantum computer expected to be available by 2029.

Quantinuum’s architecture is an end-to-end framework programmable through the company’s developer platform. It integrates tailored AI decoders, all-to-all qubit connectivity, high-fidelity physical operations, and hardware-level error correction. This architecture also allows the company to test, refine, and combine different error-correction codes and optimize between accuracy and efficiency.

In the latest study, Quantinuum used a well-known “color code” within this architecture to achieve the world-record logical fidelity result, which is equivalent to just five errors per million operations. The error rate is 10 times lower than Quantinuum’s own world record achieved last month and 100 times lower than the best published result across all other hardware modalities, which was reported by Google Quantum AI on a superconducting system.

“With this result, we’ve proven that we have the error-correction architecture and trapped-ion technology required to achieve universal fault-tolerance,” said Dr. Rajeeb Hazra, CEO of Quantinuum. “We have reduced error rates tenfold in rapid succession using a different code on the same commercial hardware, demonstrating the flexibility of our error-correction architecture. We’ve crossed the threshold necessary for exponential improvements in accuracy, reinforcing our path to Apollo and how we can help users unlock commercial value from quantum at scale.”

The study also showed that logical errors fell exponentially as Quantinuum increased the “code distance,” a technique used to understand how many physical qubits are needed to protect quantum information as the error correction scales. Each tested increase reduced the remaining logical errors by a record factor of 12, demonstrating increasingly effective error suppression as the code grows—a critical capability for scaling fault-tolerant quantum computing. Quantinuum believes this result suggests it can deliver fault-tolerance with significantly fewer qubits than are required for other modalities.

“This is a significant milestone that quantum computing researchers have been working toward for many years,” said Robin Blume-Kohout, co-director of Sandia National Laboratories’ Quantum Performance Lab, who was not involved in the study. “The paper demonstrates real, serious performance gains from quantum error correction—a logical qubit nearly 100x better than its component physical qubits. A scaled-up version of this system could reach the reliability required for useful fault-tolerant computation at a feasible size—less than a million physical qubits—which improves the outlook for practical quantum computing. These findings go a long way to retire one of the field’s central technical risks.”

In September 2026, Quantinuum used the same error-correction architecture with its Helix code to demonstrate record-setting logical memory and computation. Both studies ran on the same Helios hardware.

The two demonstrations illustrate how Quantinuum can rapidly prototype different error-correction codes within the same architecture to optimize for relative strengths in accuracy, efficiency, and speed. On Helios, Helix used 10 physical qubits per logical qubit, compared with up to 37 for the color code, while the color code delivered lower logical error rates. This provides insight into which applications pair best with each code as systems advance toward fault-tolerance.

Quantinuum’s error-correction architecture is flexible, allowing for adaptive syndrome extraction, which adjusts error-checking measurements during computation, and chain-mapping, which connects codes suited to different computational tasks. Together with efficient code structures and real-time decoding, these techniques provide multiple ways to reduce errors and resource requirements.

Quantinuum is combining its hardware, error-correction architecture, and full-stack software platform into an integrated system for fault-tolerant quantum computing. As customers prepare for this next era of computing, Quantinuum is providing the tools needed to develop and scale quantum applications capable of addressing challenges across materials science, chemistry, finance, logistics, and other critical sectors.
