Much of the attention on the European Commission’s recent proposal for a Cloud and AI Development Act (“CADA Proposal”) has focused on its proposed cloud sovereignty framework, the implications for cloud service providers and public sector cloud use, and the mechanisms intended to encourage data centre development in the EU (we discuss those aspects of the CADA Proposal in more detail in our post here).

But the CADA Proposal also contains several express references to the development of the EU quantum computing sector, which suggests that quantum computing may be embedded within the EU’s wider cloud, AI, and data centre strategy, and that the Commission may promote the development of the technology in that context (rather than treating it as a separate technology policy issue). That approach is consistent with the Commission’s July 2025 Quantum Strategy and its expected proposal for a Quantum Act later this year, both of which focus on building the industrial base for quantum computers in Europe (we describe the Quantum Strategy and the likely themes of the forthcoming Quantum Act in our prior post here).

In this post, we outline the two main mechanisms through which the CADA Proposal would support the development and deployment of quantum computing in Europe, in advance of the Quantum Act.
