Panel at CPDP 2026: From AI and Quantum to EuroStack and Digital Commons: Which Way to Digital Sovereignty?

As Big Tech controls most of the digital infrastructure on which everyday practices depend, digital sovereignty has emerged as a countervailing strategy to (re)gain control over data, technologies, and infrastructures, thereby safeguarding autonomy and self-determination in the digital era. The EU’s digital sovereignty agenda emphasises investment in sectors it considers critical, like artificial intelligence and quantum technologies. Industry and civil society also advocate for domestic alternatives to hyperscalers. The various digital sovereignty visions share commonalities; they highlight the need for European-based infrastructures that comply with EU digital rules, but raise similar concerns about underlying dependencies and geopolitical tensions. At the same time, they differ in the futures they imagine, from becoming a global leader to developing open-source solutions. This panel will investigate what digital sovereignty entails nowadays and the different pathways, from private to public digital infrastructures, towards achieving it.
