Outreach angles

-Rhonexum is a spin-out from the AQUA Lab at EPFL targeting the cabling bottleneck in quantum computers - a hardware-level constraint that limits qubit counts and coherence as systems scale toward practical quantum advantage.
-The company's Cryo-CMOS approach integrates classical control electronics at cryogenic temperatures, potentially eliminating the thousands of cables running between room-temperature controllers and dilution refrigerators in today's quantum systems.
-With $1M in pre-seed funding and EPFL institutional backing, Rhonexum is positioned at an early inflection point where quantum hardware infrastructure companies are commanding attention from deep-tech investors ahead of broader quantum commercialization.
