Listen to the episodeAbout QphoX
QphoX is a deep-tech startup founded in 2021 as a TU Delft spin-off, at the heart of the Dutch quantum ecosystem. The company develops quantum transduction systems — converting quantum signals from microwaves to optical photons — functioning as a 'quantum modem'. This infrastructure is a critical component for the future of quantum networks and quantum data centres, enabling superconducting quantum computers to interconnect over existing fibre optic. QphoX has raised multiple rounds since launch and closed a €15M round to accelerate its quantum infrastructure technology.
