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

IonQ Debuts Sixth-Generation Superion QPU Architecture Featuring On-Chip Electronic Control and CMOS Integration Trapped-ion quantum hardware developer IonQ (NYSE: IONQ) has announced its sixth-generation quantum computing platform, launching the IonQ Superion 256. The system represents the company’s first chip platform engineered for high-volume semiconductor fabrication following its acquisitions of Oxford Ionics and SkyWater Technology. IonQ has completed its initial fabrication tapeouts at SkyWater and successfully trapped first ions within prototype Superion 256 hardware deployed across its U.S. facilities, targeting commercial customer deliveries in 2027. The Superion architecture replaces external laser-based qubit addressing with Electronic Qubit Control (EQC), integrating microwave and radio-frequency control circuitry directly into the semiconductor substrate. Derived from technology integrated through the acquisition of Oxford Ionics, EQC utilizes standard planar fabrication nodes to drive qubit manipulations on-chip. By eliminating bulky free-space optical systems, the transition to electronic control reduces estimated cost-per-qubit by over 300× across the roadmap and allows full processing units to fit into standard data center server racks without custom cryogenic or optical buildouts. Fabricated using SkyWater’s pure-play foundry processes, the Superion 256 QPU underwent six rapid tapeout iterations in the first half of 2026, compressing individual design cycles from nine months down to two while delivering 12× more wafer lots than previous boutique cleanroom partnerships. The chip footprint serves as the baseline for IonQ’s concurrent development of the Superion 10K platform, which integrates cryo-CMOS logic directly onto the QPU substrate to manage multi-qubit routing, classical-quantum instruction execution, and error-correction control schedules. The Superion 10K platform represents the primary hardware execution target for IonQ’s fault-tolerant Walking Cat architecture. By pairing on-chip cryo-CMOS control with quantum low-density parity-check (qLDPC) code blocks, the platform is designed to achieve laboratory-level fault tolerance in 2027, scaling toward volume commercial manufacturing in 2028. Commercial pre-orders for Superion 256 systems opened in Q1 2026, with production-grade QPUs slated to enter remote access deployment through IonQ’s cloud infrastructure alongside on-premises server-rack deliveries.
