IceCirc GmbH is building the cryogenic electronics layer for scalable quantum computing. As a spin-off from Forschungszentrum Jülich, we combine deep expertise in cryogenic IC design, semiconductor technologies, and quantum system integration to solve one of the field’s biggest scalability challenges: control electronics.

Our roots lie in the Institute for Integrated Computing Architectures (ICA / PGI-4), where more than a decade of research has shaped a system-level understanding of scalable quantum hardware — from cryogenic readout and control to multiplexing, automated qubit tuning, and the co-design of electronics across the millikelvin, 4 K, and room-temperature domains.

At IceCirc, we turn this research foundation into ultra-low-power cryogenic ASICs that operate inside the cryostat, close to the qubits. By rethinking control and readout electronics from first principles, we reduce thermal load, cut cable complexity, and enable architectures designed to scale from laboratory systems to economically viable million-qubit quantum computers.
