Trapped-Ion Quantum Computing at Infineon

Infineon Technologies, headquartered in Neubiberg, is a global leader in semiconductor innovation with over 58,000 employees worldwide. Our expertise spans automotive semiconductors, power electronics, and IoT applications. Since 2017/18, when trapped ion quantum computing began at our Villach, Austria location as part of a Master thesis, the initiative has grown steadily. Our mission is to scale trapped ion quantum computing technology to make ion traps viable and practical for quantum applications.

Infineon’s focus is on three key building blocks: advanced trap fabrication, photonic integrated circuits (PICs), and electronics integration, all of which operate in cryogenic environments. For trap fabrication, we develop custom designs with tailored layer stacks and the option to integrate photonic technologies directly into the traps. On the electronics side, we specialize in designing high-voltage transistors optimized for cryogenic conditions, as well as circuits tailored to meet the stringent requirements of ion trap operation.

Together, these components – ion traps, photonics, and electronics – form the core of our quantum processing units (QPUs), which Infineon provides to customers to enable quantum computing applications with scalable trapped ion architectures.
