AppQInfo addressed the critical challenge of developing Europe's quantum technology capabilities and workforce to compete in the global "second quantum revolution." Europe faced a shortage of highly skilled researchers capable of bridging fundamental quantum science with real-world implementations, while technical barriers hindered practical deployment of quantum information processing systems, including limited long-distance quantum communication protocols, inefficient multiphoton sources and detectors, and lack of integrated quantum photonic platforms.
Quantum technologies promise revolutionary advances in information processing, offering unprecedented computational power, unbreakable communication security, and novel simulation capabilities for drug discovery and materials science. For European society, mastering these technologies is essential for digital sovereignty, cybersecurity, economic competitiveness, and technological leadership. The project directly supported the EU's Quantum Flagship initiative and Digital Decade goals, positioning Europe to compete with major quantum programs globally.
AppQInfo successfully trained 15 Early Stage Researchers across a consortium of 9 beneficiaries and 6 partner organizations in photonic quantum information processing. Research objectives focused on: (1) distributed multiphoton quantum protocols for secure communication, (2) quantum-enhanced processing units using integrated photonics, and (3) next-generation quantum applications and hardware.
Project Achievements: The project exceeded its goals, producing 54+ high-impact publications and breakthrough demonstrations in quantum communication, simulation, and computing. Key achievements included daylight quantum key distribution over tens of kilometers, advanced photon-number-resolving detectors, integrated quantum photonic circuits for machine learning, and polariton-based quantum simulators.
The innovative training program combined world-class research with intersectoral secondments and entrepreneurship workshops, creating a new generation of quantum technology leaders. All 15 ESRs completed doctoral training and now hold leading positions across European academia and industry.
