We’re excited to announce that we have raised £30 million in Series A funding from some of the world’s leading quantum and tech investors. Newsroom 9 January 2023 Announcing our £30m Series A funding We’re excited to announce that we have raised £30 million in Series A funding from some of the world’s leading quantum and tech investors. The round was led by Oxford Science Enterprises and Braavos Investment Advisers. Lansdowne Partners, Prosus Ventures, 2xN, Torch Partners and Hermann Hauser (founder of chip giant ARM) also participated. Founded in 2019, Oxford Ionics takes a unique approach to designing and scaling one of the most promising quantum computing technologies – trapped ions. As multiple technologies vie for position in our race for a quantum future, trapped ions have long proved superior. The highest-performing quantum systems are powered by trapped ions; Oxford Ionics’ technology has been shown to consistently outperform the others. In tests*, our trapped-ion technology holds world records for the highest performance quantum operations, longest quantum coherence time, and highest performance quantum network. Importantly, we have shown that we can maintain this performance using chips manufactured on a semiconductor production line. Record-breaking performance Oxford Ionics’ record-breaking performance stems from our pioneering approach. Until now, trapped-ion systems have largely relied on lasers to control qubits. This approach performs well for small processors, but becomes untenable and error-prone as the size of the processor scales, and the number of qubits increases. Instead of lasers, Oxford Ionics’ trapped-ion processors use a proprietary, patented Electronic Qubit Control (EQC) system to control the qubits. This allows us to combine the unrivalled quantum performance of individual atoms with the scalability and reliability of electronics integrated into silicon chips. Not only does this approach deliver the highest level of performance possible, it does so in a way that makes the Oxford Ionics processors integrable and scalable as standard. We have proven the potential of this approach in a real-world environment, producing our quantum processors in a standard semiconductor foundry through our partnership with Infineon Technologies AG . World-class team Today, the Oxford Ionics team is made up of the brightest minds across the quantum sector who between them have over 100 years of expertise in this space; 10 PhDs and more than 130 peer-reviewed scientific publications. This team has grown tenfold over the past three years and it’s our combination of pioneering vision and deep expertise that has seen us attract some of the leading quantum and tech investors of the past three decades. Before co-founding the quantum-inspired venture capital firm 2xN, investor Niels Nielsen was an early backer, and former chairman of Cambridge Quantum. Cambridge Quantum recently merged with Honeywell Quantum Solutions to form Quantinuum, one of the world’s largest integrated quantum computing companies. Fellow Oxford Ionics investor Hermann Hauser founded chip giant ARM and was an early backer of quantum technologies. We’re hiring! This latest funding round will be used to further our expansion with the hiring of people in roles across the company’s functions – from software developers and engineers to designers, scientists and a growing back-office team. Oxford Ionics’ current vacancies can be found here . Quotes: Dr Chris Ballance, co-founder of Oxford Ionics said: “If we’re to identify and unlock the true power and potential of quantum computing we need to crack the critical issues that are holding it back – scalability, integration and performance. Our unique trapped-ion approach has been developed to address all three. At Oxford Ionics, we’re focused on building technologies that will help quantum computing finish the race, not just take small, incremental steps. Our latest round of funding, and the knowledge, insight and expertise of our new investors bring us even closer to this goal.” Will Goodlad from Oxford Science Enterprises said: “Through its unique approach, developed by some of the world’s best minds in the quantum space, Oxford Ionics is laying the foundations to finally make quantum computing a scalable, integrable and viable option. Building on more than a decade at the forefront of this sector, Chris, Tom and the team have been able to demonstrate, time and again, that their work in the lab can, and will, extend to the real world and we’re thrilled to be joining them on this journey.” Niels Nielsen, co-founder of 2xN said : “Quantum computing opens up the next frontier in computing power for many industries yet getting there requires the development of qubit technologies that can be built at a massive scale. All without sacrificing power, and while keeping error levels to a minimum. Oxford Ionics’ EQC technology offers a path to bringing the power and potential of trapped ion qubits and integrating it into classical semiconductor processes.” Oxford Ionics’ latest funding round takes the total raised by the startup to £37 million.

Newsroom 6 December 2024 Oxford Ionics and Quanscient partner with Airbus to develop quantum computing applications for fluid dynamics modelling Oxford Ionics, a world leader in trapped-ion quantum computing, today announced it is working together with Quanscient, a leading provider of multiphysics simulation software, and aerospace manufacturer Airbus to develop quantum simulations for computational fluid dynamics. Partnership aims to deliver a roadmap to powerful CFD simulations on quantum hardware Airbus will participate in the consortium to provide end user feedback OXFORD, Friday 6th December, 2024: Oxford Ionics, a world leader in trapped-ion quantum computing, today announced it is working together with Quanscient , a leading provider of multiphysics simulation software, and aerospace manufacturer Airbus to develop quantum simulations for computational fluid dynamics. Used across a wide range of sectors, computational fluid dynamics (CFD) is a branch of fluid mechanics where computers simulate, analyse, and predict how fluids move. For the aerospace industry, CFD is used to predict the performance of aircraft including its lift, drag, noise, structural load capacity, and fuel efficiency. CFD relies on high-performance computers to perform large-scale and intensive computations, and quantum computing has the potential to significantly improve the effectiveness of this process. Sophisticated quantum algorithms running on powerful quantum computers could improve overall accuracy for CFD and dramatically reduce the computation time and cost – empowering the aerodynamics sector to achieve unprecedented innovations. As part of the UK’s National Quantum Computing Centre (NQCC)’s SparQ programme aimed at discovering new quantum applications, Oxford Ionics will combine its powerful quantum computers with Quanscient’s algorithms for CFD to provide a roadmap towards useful CFD simulations on quantum hardware. Specifically, the two companies will assess quantum simulations for airfoil designs and vehicle aerodynamics, with Airbus participating in the consortium to provide critical end-user feedback. While there are several organisations assessing quantum algorithms for CFD, current quantum computing hardware lacks the power and scale to reach commercially-valuable use cases. Oxford Ionics has uniquely demonstrated a path towards delivering the first machines with the performance and scalability required to tackle these real-world use cases. The company has pioneered a patented technology called ‘Electronic Qubit Control’ which uses electronics, not lasers, to control its qubits. With this approach, Oxford Ionics can integrate this powerful technology onto a thumbnail-sized electronic chip manufactured in standard semiconductor fabs – unlocking unparalleled scalability. This approach has yielded the highest performing quantum platform in the world. Earlier this year, Oxford Ionics set the world records in single-qubit gate fidelity, two-qubit gate fidelity, and quantum state preparation and measurement (SPAM). Dr Chris Ballance, Oxford Ionics co-founder and CEO commented : “Powerful quantum computers are poised to radically transform how we approach complex computational challenges like CFD – the question is no longer if, but when , we’ll see this value unlocked. We are thrilled to be working with Quanscient and Airbus to take fundamental steps towards making this future a reality. Through our partnership together, we look forward to identifying truly groundbreaking solutions to some of the hardest challenges facing the aerospace industry today.” About Oxford Ionics Oxford Ionics was co-founded in 2019 by Dr Tom Harty and Dr Chris Ballance who both hold world records in quantum breakthroughs.

In partnership with the University of Oxford’s Department of Physics, Oxford Ionics has shattered the previous world record - demonstrating a 13x reduction in SPAM errors compared to the next best approach on the market. The team achieved this groundbreaking result through developing a novel protocol that can detect and discard qubits in the wrong state. This protocol was validated through experiments performed at the University of Oxford. Figure: Data obtained by preparing, and then measuring, each of the two qubit states, |0> (red) and |1> (blue). Quantum computing promises to solve complex computational problems far beyond the capacity of any classical supercomputer. However, errors – whether caused during the preparation of the qubit into the desired state, during single- or two-qubit gates, or when reading out the qubit state at the end of the computation – are among the most significant obstacles to realising this power. Low errors in SPAM, along with two-qubit and single-qubit gates, are therefore among the three most important metrics when evaluating the precision and accuracy of a quantum computer. With these latest results, Oxford Ionics has now achieved record performance in all three. Combined with Oxford Ionics’ recent record-breaking single- and two-qubit gate fidelity results , this latest record indicates the company now has the highest performing and most reliable quantum platform in the industry. The new SPAM protocol developed will be applied to the next generation of Oxford Ionics’ quantum computers. Oxford Ionics’ quantum computers are unique owing to its patented ‘Electronic Qubit Control’ which relies on electronics, not lasers, to perform quantum gates. This approach gives the company a fundamental engineering advantage – by using electronics, Oxford Ionics can rapidly scale its quantum chips by replicating identical unit cells using the existing semiconductor manufacturing supply chain. The world records set by Oxford Ionics, in tandem with this unique approach, bring it one step closer to delivering quantum computers capable of delivering widespread commercial impact. Dr Chris Ballance, Oxford Ionics co-founder and CEO, commented: “Reliable and high-performing quantum computers hold the key to unlocking extraordinary solutions to critical problems. But to deliver a quantum computer capable of realising this future, the error rates across SPAM, single- and two-qubit gates are critical. Our team’s latest result means that Oxford Ionics has now demonstrated world-leading performance on all three of these fundamental metrics. This is an exciting leap forward for the quantum computing industry at large, and we’re excited to accelerate our efforts to put this technology in the hands of end-users.” Press Contacts GENERAL PRESS ENQUIRIES media@oxionics.com ON SOCIAL MEDIA

The mobile quantum system, called Mini-Q, is designed to be compact and robust Cyberagentur will leverage Mini-Q for applications in national security and defence Mini-Q is the first mobile variant of Oxford Ionics’ line of quantum computers OXFORD, 18th September, 2024: Oxford Ionics, a world leader in trapped-ion quantum computing, today announced that it has won a contract, alongside Infineon Technologies AG, to build a state-of-the-art portable quantum computer for Agentur für Innovation in der Cybersicherheit GmbH, or 'Cyberagentur'. Oxford Ionics and Infineon are one of three independent contractors selected by Cyberagentur, who is investing a total of €35M into the project. Founded by the German Federal Government, Cyberagentur aims to progress research and innovation in the field of cybersecurity to promote the country’s internal and external security. Cyberagentur will use Oxford Ionics’ portable quantum computer, called Mini-Q, for application development in national security and defence. Quantum computers are of particular interest for governments, as they can prove integral to national security and digital sovereignty. Government bodies around the world are already exploring different applications of quantum computing, from enhanced computing power to cryptography. Cyberagentur is specifically focused on applying quantum computing to ‘mobile defence’, meaning it can leverage a compact, lightweight, and energy-efficient mobile quantum computer for security and defence scenarios. These smaller systems are easily deployed, transported, and upgraded in the field – giving nation-states a crucial advantage. Oxford Ionics is uniquely positioned in the industry to deliver a mobile quantum computer. The company has developed a proprietary technology called ‘Electronic Qubit Control’ - meaning it uses electronics, not lasers, to control its qubits. This inherently robust technology can then be integrated onto a standard, thumbnail-sized chip produced in today’s semiconductor fabrication facilities. Through this unique approach, Oxford Ionics’ quantum computers can deliver powerful computational capabilities within an industry-leading small physical footprint where that is important for the particular needs of an organisation. Mini-Q will be the sixth quantum computer delivered by Oxford Ionics, following a contract won earlier this year with the UK’s National Quantum Computing Centre (NQCC). As an R&D partner of Oxford Ionics, Infineon AG will contribute its expertise in microfabrication of highly reliable, large-scale ion trap chips. The two companies will work together to develop increasingly powerful quantum processor units (QPUs) that leverage Oxford Ionics’ scalable manufacturing and world-leading position in qubit quality. This quality was recently demonstrated with Oxford Ionics’ world-record performance in single- and two-qubit gate fidelity and quantum state preparation and measurement (SPAM). Dr Roman Bansen, Head of Quantum Technologies at Cyberagentur , commented: "Mobile systems are particularly important for security and defence scenarios, as they can operate independently of a data connection to stationary data centres. Especially in crises or defence situations, this is essential. At the same time, mobile quantum computers also potentially offer considerable advantages for civilian applications." Dr Chris Ballance, Oxford Ionics co-founder and CEO , commented: “We are thrilled to be delivering the first mobile variant of our product line to Cyberagentur. Since our inception, we have viewed the challenge of building powerful quantum computers as an engineering project – not a science project. This approach has yielded both the highest performing chips in the world and a robust technology that can deliver industry-leading performance within a small physical footprint based on customer needs. Mini-Q represents the first of these small systems, which is uniquely engineered to suit the dynamic, fast-paced nature of national security and defence.” Oxford Ionics is rapidly accelerating the commercialisation of its technology.
