New primitives and protocols for functionalities of future hybrid classical-hybrid and quantum networks

investigación innovación I+D+i desarrollo tecnológico europeo. HORIZON Research and Innovation Actions Expected Outcome: Proposals are expected to contribute to one or more of the following: New primitives beyond Quantum Key Distribution (QKD) for future hybrid classical-quantum and quantum networks either as quantum equivalents of classical primitives or as new primitives for new practical applications, also in the relativistic setting when relevant, or as new primitives and protocols with modular, realistic integration of solutions from different cryptographic approaches, with focus on beyond-QKD applications and with gradual release on trust in hardware; Analysis of the applicability and strength of the results compared to their best classical-only counterpart, critical analysis of the formal assumptions and of performance, security proofs; Investigation of fundamental aspects of quantum information processing tasks, their eventual limits; and/or the connection between quantum computing and cryptography for insights for stronger cryptographic foundations; Roadmap for quantum cryptography and networks functionalities. Scope: The action supports research on new primitives and protocols beyond QKD for security and trust-based applications, by combining different cryptographic approa
