IonQ IONQ has launched Superion 256, its sixth-generation quantum computing platform and the foundation for future compute products. The platform has moved from early design to trapping ions in under a year, with IonQ fabricating its first fully integrated 256-qubit quantum processing units (QPUs) at its SkyWater subsidiary. The company has also trapped the first ions in prototype Superion 256 systems, which are being built simultaneously at multiple U.S. facilities.
IonQ and SkyWater jointly designed and fabricated the chip, completing six tapeouts in the first half of 2026. Working with SkyWater’s quantum foundry, IonQ cut its design cycle to two months from nine months. The teams also delivered 12 times more wafer lots over six months than they did at a previous foundry.
At the core of Superion 256 is IonQ’s Electronic Qubit Control (“EQC”), which controls trapped-ion qubits with electronics integrated directly into the chip rather than with laser systems. The underlying qubit control is manufactured using standard semiconductor processes. The chip uses the same EQC technology that IonQ used to achieve a 99.99% two-qubit gate fidelity world record in October 2025.
Designed for data center deployment, the system fits a standard server rack without requiring a bespoke buildout. It also uses less power than a rack of GPUs, while its cooling system is suited to typical data center environments.
The Superion platform scales from 256 qubits to millions of qubits. Every generation that follows Superion 256 expands use of the same ions, the same qubits, the same electronic control and the same chip fabric. Superion 10K is already underway and integrates CMOS into the chip, a scaling technique SkyWater already manufactures at volume.
IonQ is taking orders for Superion 256 now, with customer deliveries set for 2027. The company pre-sold its first system in the first quarter of 2026, while production-grade systems will also run on its cloud.
IONQ’s Peer Updates
IBM IBM and Lockheed Martin, through an offset agreement with armasuisse, Switzerland’s Federal Office for Defence Procurement, have established a hub for quantum innovation at ETH Zurich, a public research university. The new hub plans to host the country’s first IBM Quantum System Two at the Swiss National Supercomputing Center in Lugano. The project also advances the strategic collaboration between the companies, combining Lockheed Martin innovations in quantum sensing and additive manufacturing with IBM’s expertise in quantum computing and AI.
Meanwhile, Arm Holdings plc ARM has introduced CSS for Mobile 2, combining agentic AI and AI-native graphics in a single compute platform. CSS for Mobile 2 includes the new Arm Mali G2-Ultra NX GPU, the Arm C2 CPU cluster with SME2, enhanced system IP, physical implementations and a developer-ready software ecosystem in a platform optimized for next-generation mobile devices.
