Infineon Technologies has teamed up with eleQtron in Germany to jointly develop RF trapped ion Quantum Processor Units (QPUs) and a 3D ion quantum memory for scalable quantum computers.

This is the first commercial activity in the German QC ecosystem and the second for Infineon in trapped ion technology following a deal with Oxford Ionics last year.

eleQtron, based in Siegen outside Cologne, claims to be the first German quantum computer manufacturer and started in 2020 form a research group of the Department of Quantum Optics at the University of Siegen. Infineon develops and builds its trapped ion processors in Villach, Austria (above).

The key is that ion trap QPUs can be manufactured predictably, repeatably, and reliably. eleQtron’s “MAgnetic Gradient-Induced Coupling” (MAGIC) concept allows the control of qubits using radio frequency technology instead of lasers achieving record-low crosstalk between adjacent qubits. This simplifies the required scaling of quantum hardware towards higher numbers of Qubits. The partners will also investigate a novel, microstructured three dimensional ion memory to build a modular quantum processor unit.

During the development phase, Infineon will provide eleQtron with three progressively improved generations of ion traps as well as the necessary expertise to adapt them to the MAGIC concept. By employing a co-design strategy, Infineon will enable eleQtron to build ion trap-based quantum computers with successively increasing functionality. These potent quantum computers will later also be made available to industrial and scientific users via cloud access.

“As a leading company in developing quantum computing hardware, Infineon’s goal is to provide the core components and, together with our partners, enable the first meaningful quantum computing systems based on trapped-ion technology. We contribute unique technology and world-class fabrication capabilities towards achieving quantum usefulness,” said Richard Kuncic, Senior Vice President and General Manager Power Systems at Infineon Technologies.

“Being chosen by eleQtron as a QPU supplier will enable us to accelerate our quantum computing hardware roadmap and expand our business in this emerging segment.”

“Our partnership with Infineon represents a significant milestone in our strong mission to develop and competitively offer largely scalable quantum computing systems with high computing power, available for the huge business applications market,” said Jan Leisse, CEO eleQtron. “We are confident that our pioneering technology based on ion traps and radio frequency waves, combined with Infineon’s capacity and expertise in innovative QPU production, will provide the foundation for building quantum computing systems ready for first applications until mid-2027.” and
