ZuriQ's 2D trapped-ion bet: $25.5M to make quantum scaling a geometry problem

A Zürich quantum-computing startup, spun out of ETH Zürich, building trapped-ion processors whose Penning micro-traps arrange ions in two-dimensional arrays fabricated with manufacturing partner Infineon.

That a natively two-dimensional ion trap grows qubits with chip area, not line length, making geometry rather than junctions the route to thousands of qubits.

A $4.2M pre-seed in 2025 plus a $25.5M seed announced 2026-07-28 led by Quantonation, with Forward.one, Extantia and Firgun Ventures — about $29.7M total.

ZuriQ was founded in 2024 as a spin-out of Professor Jonathan Home's ETH Zürich laboratory by Dr Pavel Hrmo, Dr Tobias Sägesser and Dr Shreyans Jain. The founders spent longer in the lab to develop Penning micro-traps in which a static magnetic field replaces the oscillating fields of conventional designs, letting ions move without junctions — the property they bet would make scaling inherently easier.

ZuriQ raised a $4.2M pre-seed in 2025, then built a working demonstrator in collaboration with ETH Zürich within about 18 months: a 3×3 array of nine individually controlled ions, which the company calls the largest two-dimensional array of its kind demonstrated to date. The chips were fabricated with Infineon to show the design works with established semiconductor processes, and the team grew from four to eighteen people, hiring from IonQ, Xanadu and Hamamatsu.

On 28 July 2026 ZuriQ announced a $25.5M seed led by Quantonation, bringing total funding to about $29.7M. The capital is earmarked for hiring, research and scaling chip fabrication toward hundreds of qubits on a single chip, with thousands required for industrially useful quantum computing still the long-term target.

The one-dimensional chain was a legacy blueprint: industry leaders IonQ and Quantinuum built on it, and ZuriQ saw junction complexity becoming the scaling bottleneck.

Penning micro-traps with a static magnetic field let ions move in any direction, removing the junction constraint entirely and making the array native to the chip's area.

Infineon fabrication proved manufacturability early, addressing the most common objection to lab-born quantum architectures.

Quantonation's conviction that the quantum race is not decided gave a small Swiss spin-out patient capital to compete on physics rather than on early revenue.

Against far-ahead leaders, a startup can still compete on architecture: ZuriQ chose a different geometry and a manufacturing partner, betting scalability will beat incumbents' head start.

As of 28 July 2026, ZuriQ is an early-stage, building-phase quantum company: it announced a $25.5M seed led by Quantonation that day, taking total funding to about $29.7M after a $4.2M pre-seed in 2025. It has demonstrated a 3×3 array of nine individually controlled ions built with ETH Zürich, fabricates chips with Infineon, and has grown from four to eighteen employees with hires from IonQ, Xanadu and Hamamatsu. Its next milestone is hundreds of qubits on one chip; thousands needed for industrially useful computing remain the long-term goal, with IonQ and Quantinuum far ahead commercially.
