↓ -10%Infleqtion has achieved 30 entangled logical qubits using 80 physical qubits on its Sqale quantum computing platform, reaching a key milestone on its 2026 roadmap. The company is the first neutral-atom quantum computing firm to reach this level on a commercial system. The breakthrough combined hardware and software co-design with an AI-assisted discovery that halved the physical gates needed for a key logical operation. Infleqtion aims to deliver 100 logical qubits by 2028. The company has three customers for logical qubit circuits on the Sqale platform, including the Wellcome Leap Quantum for Bio programme. The achievement was experimentally confirmed by a signal approximately 1,000 times stronger than underlying noise. The experiment executed roughly 1,000 physical operations, marking a transition from academic experiments to commercially viable systems.
Why Oxford is one of the world's most important quantum hubs. The UK is investing in quantum. In Oxford, Infleqtion is turning that investment into an innovation engine for autonomous systems in Britain, mainland Europe, and beyond. Oxford is one of the most consequential places in the world to build quantum technology, and it is leading, not following. Its Hub for Quantum Computing via Integrated and Interconnected Implementations (QCi3) alone brings together more than 18 research institutes and 27 industrial and government partners, and the city's research base has produced one of the densest concentrations of quantum spinouts anywhere in the world. Add a government now committing serious money to quantum at a national level, and Oxford looks less like one research city among many, and more like the centre of gravity for UK quantum. Researchers, engineers, suppliers, and the customers who will eventually use the finished systems are often within a short drive of each other. Why Infleqtion is expanding in Oxford. Infleqtion has had a presence in Oxford since 2014, and Infleqtion, Inc. is now further expanding its footprint here to help turn the region's momentum into something Britain can rely on operationally, not just research it can be proud of. Britain's next generation of autonomous systems will depend on more than platforms alone. They will require trusted navigation, precision timing, advanced sensing, and the domestic capability to integrate and sustain those technologies. Infleqtion's new Quantum Innovation Centre at Oxford Technology Park will expand its UK research, production, and systems-integration capacity, providing the space and infrastructure required to move quantum technologies from development into operational use. In an increasingly volatile, uncertain, contested, and ambiguous world, trust and assured execution are no longer nice-to-haves for autonomous systems - they are the baseline requirement. The UK is investing in autonomous and uncrewed capability across defence and industry, and successful deployment will rely on resilient positioning, navigation and timing (PNT) technologies and advanced sensing: systems that can determine position and motion accurately, make sense of complex environments, and perform reliably even when signals from global navigation satellite systems (GNSS) are jammed, spoofed or denied altogether. Infleqtion's team in Oxford is developing that enabling layer across quantum computing, precision timing, sensing, and navigation. The team combines quantum science with the engineering, software and systems-integration expertise required to turn advanced technologies into useful capability. Autonomous systems are one important application of that broader expertise. How quantum sensing can support navigation without satellite signals. Q-NAV, Infleqtion's Quantum-Enhanced Inertial Navigation Systems programme, is an important example of technology developed and led from right here in Oxford. Supported by Innovate UK and developed in collaboration with the Royal Navy, Q-NAV is advancing atom-interferometry-based navigation technology for future platforms. Atom interferometry uses the behaviour of atoms to measure motion with exceptional precision, independent of any external signal. That matters because it means navigation that stays accurate and assured even when an adversary is actively trying to jam or spoof it - a critical capability as autonomous systems take on more demanding and contested missions. Integrated with established inertial-navigation technology, quantum sensing can improve the long-term accuracy and assurance of navigation systems. The programme is focused on the challenges that matter in operational settings, including performance, robustness, and integration. Infleqtion has invested to develop these highly technical solutions, and there is still real R&D and prototyping ahead. Infleqtion, Inc. is doing that work side by side with UK entities helping Infleqtion, Inc. bring these systems towards the field, building the capability to productise them here in the UK. The Royal Navy's participation brings an essential end-user perspective to the work. Engagement from the outset helps align technology development with the practical needs of the platforms and missions it may ultimately support. Connecting scientific expertise with that operational experience is part of what makes Oxford valuable as a place to develop quantum technology. Building UK quantum capability for european markets. Sovereign capability requires sustained investment in people, facilities, engineering, and supply chains. Infleqtion is growing its UK team across physics, engineering, software, manufacturing, and systems integration, whilst expanding the capacity to build, test, and deploy technology here in the UK. That UK base also positions Infleqtion, Inc. to pursue opportunities with customers and partners across mainland Europe. Oxford's rise as a quantum hub was, in many ways, inevitable, built on UKRI's early vision, decades of university research, a run of ambitious spinouts, the density of talent in the region, and now a government prepared to back the sector at scale. Infleqtion's expanded footprint in the region builds on more than a decade of that commitment, and it is aimed at ensuring the quantum technologies developed here create operational and economic value at home and around the world.

Insider Brief * Infleqtion CTO and co-founder Pranav Gokhale has received the 2026 IEEE Quantum Technical Community Distinguished Early Career Award. * The award recognizes early-career scientists and engineers for technical and scientific contributions, leadership, research impact and advancement of quantum computing. * Gokhale's work spans quantum hardware, control, software, compilation, algorithms, benchmarking and error mitigation, including his previous work at Super.tech. PRESS RELEASE - Infleqtion, a global leader in quantum computing and quantum sensing powered by neutral-atom technology, today announced that Pranav Gokhale, Ph.D., Chief Technology Officer and co-founder, has been named a recipient of the 2026 IEEE Quantum Technical Community (QTC) Distinguished Early Career Award. Presented annually by the IEEE Quantum Technical Community, the Distinguished Early Career Award recognizes scientists and engineers in the early stages of their careers whose contributions to quantum computing and engineering go above and beyond expectations for their career stage. The award recognizes excellence in technical and scientific contributions, leadership, research impact and the advancement of quantum computing. "Quantum computing will reach its full potential when we stop treating hardware and software as separate disciplines and instead design them together," said Pranav Gokhale, CTO and co-founder of Infleqtion. "I'm honored to receive this recognition from the IEEE Quantum Technical Community. I've been fortunate to work alongside an extraordinary community of researchers, engineers and collaborators who are turning fundamental advances in quantum science into systems that can solve increasingly meaningful problems." Gokhale has built a career focused on connecting the layers of quantum computing, from hardware and control to software, compilation and algorithms, to accelerate the development of practical quantum systems. His research has produced more than a dozen publications and multiple patents, along with three best paper awards. His work has addressed challenges ranging from quantum circuit optimization and benchmarking to error mitigation, quantum algorithms, and hardware-aware compilation. This dedication to bridging quantum layers was evident in Gokhale's work with Super.tech, the company he co-founded and led as CEO, which pioneered advanced quantum compilation, optimization and benchmarking software. When Infleqtion acquired Super.tech in 2022, Gokhale joined the company and brought that software expertise into Infleqtion's growing quantum computing platform. Today, Gokhale leads Infleqtion's technology strategy as CTO, spanning the company's quantum computing platform, software and applications. Infleqtion's Superstaq software uses cross-layer optimization techniques to improve quantum program performance on real devices and supports multiple quantum programming frameworks and hardware backends. "Pranav represents exactly the kind of technical leadership that is moving quantum computing from research to real-world impact," said Matt Kinsella, CEO of Infleqtion. "His ability to bridge quantum hardware, software and applications is a defining strength of Infleqtion, and this recognition from IEEE is a tremendous acknowledgement of both his contributions and his leadership in the field." Gokhale earned his Ph.D. in computer science from the University of Chicago, where his research focused on quantum computing, and holds a bachelor's degree in computer science and physics from Princeton University. Prior to co-founding Super.tech, he conducted research at the National Institute of Standards and Technology, the University of Chicago and Argonne National Laboratory. The 2026 IEEE QTC Distinguished Early Career Award will be presented during IEEE Quantum Week 2026, taking place September 13-18 in Toronto, Canada. Supporting quotes: "What stands out about Pranav is his ability to understand the full quantum computing stack and identify where advances in one layer can unlock progress in another," remarked Dr. Mark Saffman, Chief Scientist for Quantum Information at Infleqtion and Johannes Rydberg Professor of Physics at University of Wisconsin-Madison. "He brings a level of technical curiosity and ambition that is remarkable even among outstanding researchers in the field." "Pranav's combination of technical innovation and leadership can be seen throughout Infleqtion - especially the Superstaq compiler; the co-design of hardware, quantum error correction, and applications; and the development of quantum-inspired contextual machine learning," said Fred Chong, Chief Scientist for Quantum Software at Infleqtion and the Seymour Goodman Distinguished Service Professor of Computer Science at the University of Chicago. "These, in turn, have allowed Pranav to personally drive much of Infleqtion's accelerated progress in quantum computing with results that have had a high impact through traditional scientific publications, as well as actual hardware and software products."

Infleqtion has integrated NVIDIA CUDA-Q Logical with its qLDPC open-source library for quantum error correction research. The integration enables quantum error correction using approximately six physical data qubits per logical qubit — roughly five times fewer than surface-code approaches. Working with an early-access version of CUDA-Q Logical, Infleqtion researchers constructed and validated a high-rate quantum error correction code. This physical-to-logical qubit ratio below 10:1 represents progress toward the company's architectural target for near-term systems. The high physical-qubit overhead of error correction remains a central obstacle between current quantum computers and commercially useful ones. High-rate codes pack more logical information into the same machine, though the advantage requires the entire system to be built accordingly. Infleqtion open-sourced qLDPC last year alongside researchers from JPMorgan Chase.
