Oxford Ionics

Oxford Ionics describes itself as a quantum computing company building compact, data-centre-ready quantum computers. Its website says its systems are field upgradeable, with a credit-card-sized QPU that can be swapped while the surrounding infrastructure remains in place. The company also says its infrastructure fits within a standard double server rack and integrates with computing stacks including AWS and NVIDIA.

The company’s technology is based on trapping and controlling qubits with electronics integrated onto a classical chip made in standard semiconductor fabs. Oxford Ionics refers to this as Electronic Qubit Control, positioning it as the basis for scaling its systems. Its published roadmap lists 16–64 qubit systems in 2025, 256+ qubit devices in 2026, and 10,000+ qubit systems in 2027.

The homepage also states that IonQ completed the acquisition of Oxford Ionics, indicating current ownership by IonQ. Oxford Ionics further states that it delivered a quantum computer to the UK’s National Quantum Computing Centre.
