Infineon and ZuriQ Deepen Partnership to Advance Scalable Quantum Chips

Infineon and ZuriQ Push the Limits of Trapped‑Ion Quantum Chips

The collaboration between German semiconductor giant Infineon Technologies and Swiss quantum startup ZuriQ AG marks a significant step toward making quantum processors that can scale beyond the laboratory. By combining ZuriQ’s novel two‑dimensional Penning micro‑trap architecture with Infineon's mature semiconductor manufacturing, advanced packaging, and integrated photonics capabilities, the partners aim to build larger, more reliable trapped‑ion chips that could power real‑world quantum applications.

A New Geometry for Trapped Ions

Traditional trapped‑ion computers arrange ions in a single line, which forces complex junctions when the system grows. ZuriQ sidesteps this limitation with a Penning micro‑trap that uses electric and magnetic fields to shuttle ions across a flat chip. The result is a clean, two‑dimensional grid that can, in principle, host hundreds or thousands of qubits without the overhead of routing junctions. The recent demonstration of a 3×3 array of nine individually controlled ions was the largest 2‑D trapped‑ion system built to date and proved the viability of the architecture.

Leveraging Industrial Manufacturing

Infineon brings to the table more than 25 years of experience in high‑volume semiconductor production. Its expertise in process development, advanced packaging, and integrated photonics is essential for turning ZuriQ’s physics‑driven design into a manufacturable product. The partnership will explore how to embed the ion traps directly onto silicon wafers, integrate laser delivery systems, and develop packaging that protects fragile quantum states while allowing mass production.

Toward Commercial‑Grade Quantum Processors

The joint effort is focused on scaling the qubit count while maintaining coherence and gate fidelity—key metrics for fault‑tolerant quantum computing. By combining ZuriQ’s design with Infineon’s industrial tools, the team hopes to reduce the cost and complexity of building large‑scale quantum chips. The goal is not only to push the boundaries of physics but also to create a production line that can deliver quantum processors for sectors such as drug discovery, materials science, and AI.

Strengthening Europe’s Quantum Ecosystem

This partnership underscores Europe’s commitment to staying competitive in the quantum race. With Infineon’s global supply chain and ZuriQ’s cutting‑edge research, the collaboration could accelerate the deployment of quantum technology across the continent. It also signals to other European players that scalable, manufacturable quantum hardware is within reach.

What Comes Next?

The next milestones include fabricating larger 2‑D arrays, integrating photonic interconnects, and validating the system’s performance under realistic workloads. Success will pave the way for commercial quantum processors that can be produced at scale, bringing quantum advantage closer to everyday applications.
