Company profile
Oxford Ionics
Oxford company designing trapped-ion quantum processor chips using electronic qubit control implemented in standard semiconductor fabrication processes; acquired by IonQ in 2025 with Oxford operations retained.
Company overview
Developing trapped-ion quantum computers, Oxford Ionics uses Electronic Qubit Control to trap and manipulate ions through electronics integrated onto silicon chips. Its quantum processor units combine electrodes, integrated antennas, electronics and photonic technology, with barium ions held above the chip surface. The chips are produced on CMOS-compatible production lines using the existing semiconductor supply chain, and can use conventional microelectronic packaging and printed circuit boards. Modular unit cells support parallel operations and qubit connectivity. The company supplies complete quantum computers with replaceable quantum processor units, allowing on-site upgrades while retaining the surrounding infrastructure. Its systems are designed for integration into data centres and existing computing environments. UK activity includes the deployment of its QUARTET quantum computer at the National Quantum Computing Centre in 2025. Customers and intended users include research institutions, government bodies, high-performance computing facilities and enterprises. The website also reports that IonQ has completed its acquisition of Oxford Ionics.
