Quantinuum

Our partner NVIDIA’s new video highlights the UK’s place leading global revolutions — from steam and electricity to AI and quantum computing. With roots in the US and UK, Quantinuum is at the heart of the collaborative movement to drive the next era of quantum and AI.

We're closing gaps others miss with our world-class team and industry-leading hardware. In particular, we’ve been asking: how well do quantum error correction (#QEC) gadgets actually perform on real hardware? Are the assumptions behind scalable fault tolerance holding up in practice? In a new paper, we develop a protocol to directly characterize the distribution of logical errors arising from QEC measurements. Our new protocol is robust, syndrome-aware, and applies to complex noise sources such as space-time correlated noise. We benchmarked our approach using Quantinuum’s System Model H1, with excellent results showing improved logical fidelities. Most existing methods have critical gaps, like averaging over distinct measurements or ignoring critical mid-circuit effects. Our protocol closes these theoretical gap, enabling fine-grained diagnostics of QEC primitives and testing key assumptions behind scalable fault tolerance. We are focused on de-risking the path to large-scale fault-tolerant quantum computing, and we are doing the work to get there. This work is platform-agnostic — relevant to anyone working on quantum hardware, QEC theory, or benchmarking tools, because we believe in contributing to our community.

This week, Quantinuum President & CEO, Dr. Rajeeb Hazra, delivered a landmark keynote at the Quantum World Congress—on the same stage where, just one year ago, he announced our bold vision: to build the world’s first universal, fully fault-tolerant quantum computer, Apollo, before the end of this decade. This year, against the backdrop of the International Year of Quantum Science and Technology, Raj highlighted the concrete advances Quantinuum has made toward that vision 🔸 Becoming the first—and only—company to overcome the hurdle of executing a fully fault-tolerant universal gate set with repeatable error correction  🔸 Setting 8 world records, including a quantum volume of 33.5 million and “four 9s” logical magic state fidelity 🔸 Deploying a new software stack that enables developers to code with greater flexibility and efficiency than ever before 🔸 Introducing GenQAI, a framework that leverages data from our systems to advance AI capabilities 🔸 Delivering on-schedule with our roadmap, beginning with the upcoming launch of Helios—the industry’s first 50 logical qubit commercial system We are firmly on track for Apollo, and the road ahead is brighter than ever. See you at QWC 2026! In the comments: Barron’s published a feature article on Raj’s keynote, detailing Quantinuum’s “turning point” year.

The focus: AI factories, accelerated model research, and the emerging crossover between AI and quantum. Our founder and vice chairman, Ilyas Khan, KSG, joined industry leaders at events led by US President Donald Trump, UK Prime Minister Sir Keir Starmer, US Commerce Secretary Howard W. Lutnick, and UK Business Secretary Peter Kyle.   The mood mixed celebration with conviction. NVIDIA’s Jensen Huang recently said quantum computing is “reaching an inflection point.” Yesterday showed it plainly and in historic terms: the industry is no longer edging forward — it’s accelerating and we are driving progress.

Moving on up: We’ve just hit 33.5 million in Quantum Volume! This is a 4x improvement since we met our five-year challenge of reaching 8 million back in May. Not only is this the highest ever recorded but it’s 16,000x greater than the next runner up. Originally developed by IBM in 2020 as a holistic measure of computational power, Quantinuum has led in this key performance benchmark since 2021. Quantum Volume (QV) is an excellent benchmark for system performance because it demands that all parts of the system work well, and work together, to generate these results. Our lead in QV means that our customers enjoy the best quantum computers available. This is all thanks to our world-leading hardware—and the team behind it. A quantum volume of 33 million marks another high water mark for us – but we won’t stop here. Our Helios system, coming online later this year, is going to take performance to a level never seen before.
