Lausanne-based Rhonexum raises €867.5k to advance cryogenic electronics for scalable quantum computing

Lausanne-based Rhonexum has secured €867.5k in pre-Seed funding, signaling a significant advancement in the field of cryogenic electronics crucial for the development of scalable quantum computers. This investment, led by QDNL Participations and supported by Venture Kick and various Swiss innovation programs, underscores the growing importance of enabling technologies for the next generation of computing. The company aims to transition quantum systems from laboratory-scale experiments to practical, large-scale machines. Rhonexum's core innovation lies in developing electronics capable of operating at cryogenic temperatures, near absolute zero, a prerequisite for quantum computing. Unlike conventional electronics, their proprietary models and software tools allow for the creation of components using standard semiconductor processes that function reliably within these extreme environments. This breakthrough promises to mitigate thermal-load losses and reduce cabling complexity, addressing a major scalability bottleneck in quantum computing by enabling electronics to operate in close proximity to qubits. The funding will accelerate Rhonexum's product development, expand its design team, and facilitate the delivery of an initial industrial-grade cryogenic electronics product to early customers. This move is pivotal for enabling the wider adoption and commercialization of quantum computing, with potential future applications extending to space technology and advanced sensing, thereby contributing to Europe's growing prowess in cutting-edge digital infrastructure.
