QuantERA III is aimed at strengthening Europe’s leadership in Quantum Technologies (QT) through a highly coordinated transnational approach. Building on the success of its predecessors, QuantERA III will subsidise cutting-edge research by launching a Cofunded Call for Proposals in 2025, backed by over €37 M in national contributions, targeting two critical areas: Quantum Phenomena and Resources and Applied Quantum Science. Additional €15 M of the EU contribution shall be allocated to both the Cofunded Call budget and the project tasks. By supporting projects that lay the foundations for future QT advancements and translating quantum science into practical applications, the Programme will catalyse new directions in the field, ensuring the EU’s leading status in this transformative technology sector. QuantERA III’s objectives align seamlessly with the EC’s Work Programme, as it seeks to address fragmentation in QT research across the European Research Area (ERA) and develop synergy in transnational research efforts. QuantERA III is designed to meet the highest standards of excellence, capitalising on the collective expertise and resources of 40 RFOs from 30 countries (incl. 14 Widening countries) – the Programme will achieve its objectives through a well-structured approach that leverages the unique strengths of each Consortium partner. It will explore further funding opportunities, continue mapping QT policies in Europe, address gender imbalance in QT, and – liaising with the Quantum Flagship and other stakeholders – engage with non-European countries to expand its reach and amplify its impact. The Consortium aims to build a sustainable vision for QuantERA beyond Horizon Europe, benefitting the entire ERA by enhancing Europe’s innovation capacity and maintaining its competitive edge on the global stage. Through its comprehensive framework of six Work Packages, the proposal ensures the realisation of its goals, aligning perfectly with the EC’s priorities for R&I.
