IonQ has entered into a definitive agreement to acquire Oxford Ionics in a deal valued at $1.075 billion, signaling a major consolidation in the quantum computing space. The transaction—comprised of approximately $1.065 billion in IonQ common stock and $10 million in cash—combines IonQ’s quantum compute and networking stack with Oxford Ionics’ record-setting ion-trap technology manufactured on standard semiconductor chips. The merger is expected to significantly advance the roadmap toward building the world’s most powerful and commercially viable quantum computers.
IonQ, based in College Park, Maryland, is a leader in trapped-ion quantum computing, with a growing enterprise customer base and recent acquisitions of Lightsynq and Capella. Oxford Ionics, headquartered in Oxford, UK, has developed quantum processors with industry-leading fidelity levels and novel architecture that integrates with conventional chip manufacturing processes. Together, the companies plan to deliver systems with 256 physical qubits and 99.99% fidelity by 2026, scaling to over 10,000 qubits with ultra-high logical accuracy by 2027, and eventually reaching 2 million physical qubits by 2030.
The combined entity will maintain and expand its presence in the UK, building on Oxford Ionics’ R&D capabilities and strategic partnerships with the UK National Quantum Computing Centre and government-led Quantum Missions program. Co-founders Dr. Chris Ballance and Dr. Tom Harty will continue leading Oxford Ionics as part of IonQ, advancing the next generation of quantum platforms aimed at drug discovery, financial modeling, logistics, materials science, cybersecurity, and aerospace. The company also reaffirms its commitment to UK and US government partnerships as it scales quantum computing applications for public and private sector customers.
