The Catalan government will invest nearly €10 million in a pioneering quantum technology initiative, creating the Barcelona Quantum Ring. This new infrastructure will safeguard the region’s most critical data and communications.

On Monday, March 16, the Generalitat de Catalunya announced the launch of the bidding process for the network’s deployment, allocating an initial €8.2 million for the core infrastructure. Backed by the European Regional Development Fund (FEDER), this funding supports a broader quantum strategy. It aims to future-proof Catalonia’s essential services against the emerging threat of cyberattacks from quantum computers.

An ‘Unhackable’ Network for a Digital Age

As computing power evolves, experts warn that future quantum computers could break current encryption standards, which protect online banking and government secrets. In response, scientists are developing quantum cryptography. This method uses the principles of quantum mechanics to create theoretically unhackable communication channels.

The Barcelona Quantum Ring will use Quantum Key Distribution (QKD) technology to secure data transmissions. The Centre for Telecommunications and Information Technologies (CTTI), which manages the Generalitat’s existing fibre optic network, will integrate this system.

The project has an ambitious timeline. The first four strategic nodes of the ring should be operational by 2027. This initial phase will connect key government and security hubs, such as:

  • The Palau de la Generalitat, the seat of the Catalan government in central Barcelona.
  • The main CTTI data centre in Hospitalet de Llobregat.
  • The Agència Tributària de Catalunya (Catalan Tax Agency).
  • The Egara complex, a central command for the Mossos d’Esquadra police force, in Sabadell.

By 2028-2029, the network is slated to expand to 12 nodes, with long-term plans to encompass around thirty strategic locations. These will include critical infrastructure such as health databases, major hospitals like the recently expanded Hospital del Mar, and the Ferrocarrils de la Generalitat de Catalunya (FGC) railway network.

Catalonia’s Quantum Ambitions

This major investment underscores Catalonia’s position as a leading European hub for quantum science and technology. The region is home to world-renowned research centres like ICFO – The Institute of Photonic Sciences, located in Castelldefels, which has been instrumental in developing the technology. Local companies, such as ICFO spin-off LuxQuanta, are also at the forefront of commercialising these advanced systems.

The Barcelona Quantum Ring is not an isolated project. It forms a crucial part of the European Quantum Communication Infrastructure (EuroQCI) initiative, a pan-European programme coordinated by the European Commission. The EuroQCI aims to build a secure quantum communication network that will span the entire EU, protecting sensitive data and critical infrastructure across the continent.

The project launches amid significant political maneuvering in the Catalan parliament. Led by Salvador Illa, the government is pursuing ambitious, long-term investments despite a precarious political situation; its 2026 budget currently hangs in the balance. As Barna.News has reported, the Catalan government faces a critical budget impasse. This could impact a wide range of public spending if an agreement is not reached.

By securing its communications with next-generation technology, the Generalitat aims to protect citizens and services, and solidify Barcelona’s reputation as a global centre for technological innovation.
