Key features

Ultra-high fidelity qubits

Our trapped-ion qubits have record-breaking performance in all key quantum computing metrics, including 99.99% two-qubit fidelity, drastically reducing error correction overheads and unlocking value sooner.

Field-upgradable systems

Oxford Ionics’ quantum computers can be upgraded to the highest performing systems by swapping out the credit-card-sized Quantum Processor Unit (QPU) – keeping your business at the cutting edge.

Ultra-low cross-talk parallel gates

Modular, unit-cell based architecture means we can run many gates in parallel with no effect on neighbouring operations. Running operations in parallel, rather than sequentially, dramatically reduces time to solution and increases algorithm efficiency.

All-to-all connectivity

Our flexible QPU architecture enables all-to-all qubit connectivity, vastly increasing algorithm efficiency and enabling a wider array of Quantum Error Correction (QEC) protocols.

Mid-circuit measurement

Feed-forward by mid-circuit measurement supports Quantum Error Correction (QEC) protocols and unlocks multiple applications, including quantum-classical algorithms.

Highly automated

Our technology minimises physical upkeep requirements and is self-calibrating, delivering ultra-stable, highly automated turnkey quantum computers designed to maximise uptime.

Benefits

Unparalleled compute power

Our quantum computers enable you to run complex algorithms and novel error correction protocols with speed and efficiency, unlocking a breadth of possible applications.

High uptime & reliable results

Our systems are highly automated, robust, and low-maintenance. This delivers maximum stability and uptime, allowing you to run your solutions consistently and with ease.

Integration into your world

Our quantum computers are compact and require no specialised facilities or bespoke labs, fitting seamlessly into existing computing infrastructure and delivering value from day one.

Future-proof

Your business can stay at the cutting edge of innovation with simple, on-site upgrades to the most advanced QPUs – so the system you buy today continues to generate value up to thousands of qubits and beyond.

Whether conducting crucial early research or groundbreaking algorithm development, our quantum computers empower universities and national laboratories to explore complex problems beyond the reach of classical computing. By leveraging our high-performance quantum computers, researchers can experiment with cutting-edge quantum architectures, validate theoretical models, and train the next generation of scientists in quantum technologies.

Quantum computers are a crucial technology for government institutions, addressing key national priorities like digital security, climate modelling, and infrastructure optimisation. Oxford Ionics’ quantum computers can enable government agencies to simulate complex physical systems, strengthen cybersecurity defences, and accelerate breakthroughs in materials science and energy research – driving national innovation, security, and digital sovereignty.

With seamless integration into existing data centres, Oxford Ionics quantum computers help HPC customers extend their capabilities beyond classical computing to tackle problems such as advanced machine learning, material modelling, engineering simulation, and large-scale optimisation. By leveraging our quantum computers alongside traditional supercomputers, HPC facilities can accelerate time-to-solution for complex workloads, reduce energy consumption for certain tasks, and offer cutting-edge computational services for their clients.

Quantum computing will pave the way for enterprises to develop fundamental, cutting-edge innovations across a range of industries, including financial services, pharmaceuticals, engineering, and manufacturing. By deploying Oxford Ionics quantum computers today, enterprises can become quantum-ready, gaining a competitive advantage through faster insights, earlier exploration of new product and service offerings, and a head start on integrating this transformative and inevitable technology.

Case studies

UK National Quantum Computing Centre

In 2025, we deployed a quantum computer called QUARTET to the UK’s National Quantum Computing Centre (NQCC). The NQCC is the UK’s National centre for quantum computing, focused on enabling the adoption of quantum computing technology across industry, academia, and government.

QUARTET is a full-stack, trapped-ion quantum computer that leverages Oxford Ionics’ proprietary Electronic Qubit Control technology. Quartet will be used for applications and use case research, as part of the NQCC’s flagship SparQ program, aimed at accelerating the adoption of quantum technology across UK enterprises.

DARPA Quantum Benchmarking Initiative

With a long history of backing transformational advances, DARPA is the United States’ primary research and development agency focused on identifying cutting-edge technologies with the potential for national security applications. Through its Quantum Benchmarking Initiative, the agency has solicited innovative approaches to constructing utility-scale fault-tolerant quantum computers.

Oxford Ionics was selected by DARPA to advance to the first round of its QBI program after showing DARPA its existing technology capabilities and its clear roadmap towards fault-tolerant quantum computers. Its proposed approach rests on three crucial pillars: unmatched operation fidelities, unparalleled scalability, and built using technologies that exist today.
