QphoX: A Dutch Quantum Startup Driving Europe’s Secure Communications Autonomy
Europe’s emerging quantum communications specialist QphoX is a Dutch deep-tech startup founded in 2021 as a spin-off from TU Delft. The company is developing a novel “quantum modem” based on microwave-to-optical transduction to network superconducting quantum processors over fiber optic links[1][2]. Its core innovation allows room-temperature optical channels to carry quantum signals from cryogenic qubits, potentially enabling scalable quantum computing clusters and a secure quantum internet. QphoX has already demonstrated single-qubit optical readout in collaboration with partners and secured significant EU and national funding. Its technology addresses a key European priority – enabling indigenous quantum networks and reducing dependence on external (e.g. Chinese) cryptographic infrastructure[3][4]. This report examines QphoX’s organizational profile and technology portfolio in detail, evaluating its contribution to EU strategic autonomy, NATO interoperability, collective deterrence, transatlantic cooperation, and supply-chain resilience.
