IonQ Acquires Oxford Ionics in $1.1 Billion Quantum Computing Deal
On June 9, 2025, US-based quantum computing company IonQ announced the acquisition of UK startup Oxford Ionics in a transaction valued at approximately $1.1 billion.
The deal, consisting of $1.065 billion in IonQ common stock and around $10 million in cash, is expected to close later this year, pending regulatory approval136.
Oxford Ionics, spun out of the University of OxfordDealroom has a profile for this one. Try Dealroom → in 2019 by Chris BallanceDealroom has a profile for this one. Try Dealroom → and Tom HartyDealroom has a profile for this one. Try Dealroom →, specialises in trapped-ion quantum computing. Unlike traditional approaches that rely on complex laser systems, Oxford Ionics uses electronic qubit control integrated into standard silicon chips, enabling scalable manufacturing using existing semiconductor processes.
IonQ, also focused on trapped-ion technology, aims to combine its quantum computing stack with Oxford Ionics’ chip-based innovation.
The merged company targets significant technical milestones: systems with 256 physical qubits at 99.99% accuracy by 2026, more than 10,000 physical qubits by 2027, and up to 2 million by 2030. The founders of Oxford Ionics are expected to remain with IonQ after the acquisition.
Both companies anticipate that their complementary technologies and expertise will accelerate the development of scalable, high-fidelity quantum computers, strengthening their position in a rapidly evolving global market.
