This marks Quantinuum's second breakthrough in two months,\ndemonstrating how its highly accurate trapped-ion hardware and flexible\narchitecture work together to deliver rapid improvements in accuracy.\n\n\n\nThe achievement reinforces Quantinuum's error-correction leadership and\nvalidates that its accuracy performance is now within the target range for\nApollo, the company's planned universal fault-tolerant quantum computer\nexpected to be available by 2029.\n\nQuantinuum's architecture is an end-to-end framework programmable through the\ncompany's developer platform. It integrates tailored AI decoders, all-to-all\nqubit connectivity, high-fidelity physical operations, and hardware-level\nerror correction. This architecture also allows the company to test, refine,\nand combine different error-correction codes and optimize between accuracy and\nefficiency.\n\nIn the latest study, Quantinuum used a well-known 'color code' within this\narchitecture to achieve the world-record logical fidelity result, which is\nequivalent to just five errors per million operations. The error rate is 10\ntimes lower than Quantinuum's own world record achieved last month and 100\ntimes lower than the best published result\n(https://www.nature.com/articles/s41586-024-08449-y) across all other\nhardware modalities, which was reported by Google Quantum AI on a\nsuperconducting system.\n\n\"With this result, we've proven that we have the error-correction architecture\nand trapped-ion technology required to achieve universal fault-tolerance,\"\nsaid Dr. Rajeeb Hazra, CEO of Quantinuum. \"We have reduced error rates tenfold\nin rapid succession using a different code on the same commercial hardware,\ndemonstrating the flexibility of our error-correction architecture. We've\ncrossed the threshold necessary for exponential improvements in accuracy,\nreinforcing our path to Apollo and how we can help users unlock commercial\nvalue from quantum at scale.\"\n\nThe study also showed that logical errors fell exponentially as Quantinuum\nincreased the 'code distance,' a technique used to understand how many\nphysical qubits are needed to protect quantum information as the error\ncorrection scales. Each tested increase reduced the remaining logical errors\nby a record factor of 12, demonstrating increasingly effective error\nsuppression as the code grows—a critical capability for scaling\nfault-tolerant quantum computing. Quantinuum believes this result suggests it\ncan deliver fault-tolerance with significantly fewer qubits than are required\nfor other modalities.\n\n\"This is a significant milestone that quantum computing researchers have been\nworking toward for many years,\" said Robin Blume-Kohout, Co-director of Sandia\nNational Laboratories' Quantum Performance Lab, who was not involved in the\nstudy. \"The paper demonstrates real, serious performance gains from quantum\nerror correction—a logical qubit nearly 100x better than its component\nphysical qubits. A scaled-up version of this system could reach the\nreliability required for useful fault-tolerant computation at a feasible\nsize—less than a million physical qubits—which improves the outlook for\npractical quantum computing. These findings go a long way to retire one of the\nfield's central technical risks.\"\n\nIn September 2026, Quantinuum used the same error-correction architecture with\nits Helix code to demonstrate record-setting logical memory and computation.\nBoth studies ran on the same Helios hardware.\n\nThe two demonstrations illustrate how Quantinuum can rapidly prototype\ndifferent error-correction codes within the same architecture to optimize for\nrelative strengths in accuracy, efficiency, and speed. On Helios, Helix used\n10 physical qubits per logical qubit, compared with up to 37 for the color\ncode, while the color code delivered lower logical error rates. This provides\ninsight into which applications pair best with each code as systems advance\ntoward fault-tolerance.\n\nQuantinuum's error-correction architecture is flexible, allowing for adaptive\nsyndrome extraction, which adjusts error-checking measurements during\ncomputation, and chain-mapping, which connects codes suited to different\ncomputational tasks. Together with efficient code structures and real-time\ndecoding, these techniques provide multiple ways to reduce errors and resource\nrequirements.\n\nQuantinuum is combining its hardware, error-correction architecture, and\nfull-stack software platform into an integrated system for fault-tolerant\nquantum computing. As customers prepare for this next era of computing,\nQuantinuum is providing the tools needed to develop and scale quantum\napplications capable of addressing challenges across materials science,\nchemistry, finance, logistics, and other critical sectors.\n\nRead the full research here: quantinuum.com/fault-tolerance-by-2029 \n\nAbout Quantinuum\n\nQuantinuum is a leading quantum computing company offering a full-stack\nplatform designed to make quantum computing deployable in real-world\nenvironments.
