Infineon Technologies and Swiss company ZuriQ, an ETH Zurich spin-off, announced on 7 October 2026 that they are expanding their collaboration on scalable quantum-computing hardware. The companies said earlier development work used a Penning micro-trap architecture to control nine ions individually in a two-dimensional 3×3 array. They described it as the largest two-dimensional array of its kind at the time. The next phase is intended to advance the design and manufacturing work needed to move toward significantly larger qubit counts; the announcement did not report a larger processor as completed.

ZuriQ’s approach differs from some conventional trapped-ion systems that arrange ions in a one-dimensional chain. Its architecture uses electric and magnetic fields to move ions directly across a chip in two dimensions. ZuriQ says the Penning micro-trap design avoids complex junction structures, which may make larger arrays easier to accommodate. The release does not say that a larger processor is finished, that a product is ready for commercial use or that scale-up performance has already been validated. It describes a development objective and a previous experimental result, with no quantified delivery schedule.

The collaboration joins the physical architecture with semiconductor manufacturing capabilities. ZuriQ contributes its trap architecture and quantum processor design, while Infineon says it will bring process development, advanced packaging and integrated-photonics expertise. Ion control on a chip requires optical, electronic and packaging components to work together, so manufacturability is an engineering challenge alongside increasing qubit counts. The announcement frames the work as research and development toward future systems. It does not disclose a project budget, a production commitment or a named customer application.

Quantum processors may offer advantages for certain specialised computational problems, but this announcement is not evidence of a commercial advantage in any particular application. The earlier nine-ion demonstration is a technical milestone on a possible scaling path; it does not establish a completed, reliable, fault-tolerant large-scale system. The companies said they intend to target larger qubit counts but gave no numerical target, timetable, investment figure or product launch date. The development should therefore be read as a partnership combining quantum-device design and industrial semiconductor expertise, rather than as the delivery of a commercial quantum computer.
