RExQTCS - Romanian Excellence Quantum Technologies enhancing Cybersecurity

Abstract

The RExQTCS (Romanian Excellence in Quantum Technologies enhancing Cybersecurity) project aims to establish a national center of excellence that integrates leading expertise in quantum technologies and cybersecurity across major Romanian universities. By leveraging strong international research performance and existing infrastructure — most notably the Romanian National Quantum Communication Infrastructure (RoNaQCI), part of the European Quantum Communication Infrastructure (EuroQCI) — the project seeks to position Romania at the forefront of quantum-secure digital innovation. RExQTCS proposes a comprehensive research and innovation agenda structured around frontier and exploratory research in classical and post-quantum cryptography, quantum technologies, security of enterprise and critical infrastructures, and secure communication protocols for the future quantum internet. The project will address key challenges such as vulnerability to quantum attacks, scalability and security of QKD networks, and the integration of quantum technologies into real-world systems. Interdisciplinary approaches combining cryptography, quantum physics, artificial intelligence, distributed systems, and network security will enable the development of novel, high-impact solutions for critical infrastructures, public administration, and industry. Beyond research, the project emphasizes education, innovation, and societal impact. Through the RExQTCS School, it aims to train a new generation of specialists, producing at least 25 PhD graduates and fostering a sustainable talent pipeline. Strong industry collaboration and technology transfer will accelerate the adoption of quantum-secure solutions, while national awareness programs will promote cybersecurity culture among citizens, institutions, and policymakers. Ultimately, RExQTCS seeks to strengthen Romania's role in the European quantum ecosystem, contributing to secure digital transformation and advancing the development of the future quantum internet.
