Oxford Ionics

Oxford Ionics is a UK company building trapped-ion quantum computers in which the qubits are manipulated with microwave signals delivered from integrated silicon chips instead of the laser systems used by most other ion-trap developers. Its ion traps are fabricated using semiconductor-style processes, and the company has published high-fidelity single- and two-qubit gate results obtained with this electronic control scheme, arguing that chip-based control is the more manufacturable route to large qubit counts. It is one of the more prominent European trapped-ion efforts, competing with laser-driven systems from Quantinuum, IonQ and others.

IonQ Debuts Sixth-Generation Superion QPU Architecture Featuring On-Chip Electronic Control and CMOS Integration

IonQ announced Superion 256, its sixth-generation trapped-ion quantum processor, describing it as the company's first chip platform designed for high-volume semiconductor manufacturing. The architecture uses on-chip electronic control and CMOS integration, and IonQ has completed initial fabrication tapeouts at SkyWater after acquiring Oxford Ionics and SkyWater Technology.

OutlookPlausible

If the tapeouts yield working devices, IonQ could move from hand-built ion trap assemblies to wafer-scale production, allowing it to place multiple identical Superion-class processors in cloud data centers within two years.
