Rhonexum

Rhonexum is a Swiss quantum technology startup that develops specialized electronics designed to operate reliably at cryogenic temperatures, close to absolute zero. These conditions are essential for quantum computing, where conventional electronics fail. By integrating proprietary models and software tools, Rhonexum designs components using standard semiconductor processes that can function directly within cryogenic environments. This approach addresses a significant scalability challenge in quantum computing by bringing control electronics closer to quantum processors, leading to reduced system complexity and more compact, efficient architectures. The company was founded by Vicente Carbon and Dr. Hung-Chi Han, leveraging their expertise in cryogenic semiconductor physics, systems engineering, and deeptech industrialization. Rhonexum aims to be a key provider of cryogenic electronics for scalable quantum systems, facilitating the transition from laboratory setups to large-scale quantum machines.
