Infineon and ZuriQ Expand Partnership to Scale Quantum Chips
Infineon Technologies and Swiss quantum computing company ZuriQ have expanded their collaboration to advance scalable trapped-ion quantum processors, bringing together quantum architecture development and industrial semiconductor manufacturing.
Announced on October 7, the partnership builds on earlier technical progress by the two companies. Their previous work demonstrated a 3×3 array of nine individually controlled ions, which Infineon describes as the largest two-dimensional array of its kind achieved to date. The next phase will focus on scaling the technology to significantly larger qubit counts.
ZuriQ’s 2D Penning Micro-Trap Architecture
ZuriQ's approach uses a two-dimensional Penning micro-trap architecture that confines and moves ions using electric and magnetic fields. Unlike conventional trapped-ion systems that generally arrange ions in one-dimensional chains, the architecture allows ions to be positioned across a two-dimensional chip.
The design is intended to reduce some of the complexity associated with junction structures used to move ions in conventional architectures. ZuriQ says its micro-fabricated chips can support reconfigurable ion arrays, providing a potential route toward systems containing thousands of qubits.
Infineon Brings Semiconductor Manufacturing Expertise
Infineon will contribute its expertise in semiconductor manufacturing, advanced packaging and integrated photonics. The combination is intended to help move ZuriQ’s technology beyond laboratory demonstrations toward more manufacturable quantum processing units.
The companies will also explore how Infineon’s semiconductor and photonic processes can be integrated with ZuriQ’s architecture. The goal is to develop quantum hardware that can eventually support larger processors and commercially relevant applications.
Infineon is already involved in several European quantum pilot-line initiatives focused on industrialising different quantum technologies, including ion traps, superconducting systems and semiconductor-based quantum chips.
Scaling Toward Commercial Quantum Systems
The expanded collaboration reflects a broader challenge in quantum computing: demonstrating individual qubits or small arrays is not enough to build commercially useful machines. Hardware must also be manufactured with precision, integrated reliably and scaled to much larger numbers of qubits.
For ZuriQ and Infineon, the immediate objective is to increase the size of the trapped-ion arrays while developing manufacturing processes that can support future generations of quantum processors. The companies say the technology could eventually contribute to applications in areas including medicine, logistics, materials science and artificial intelligence.
The partnership does not mean large-scale commercial quantum computers are already in production. Instead, it represents another step toward industrialising a trapped-ion architecture that is still under development.
