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

Opens 2 Mar 2027

The EU's Horizon Europe programme expects to make 1 award of €4 million, from a total budget of €4 million. Applications close on 15 Sep 2027 (EU calls usually close at 17:00 Brussels time). Organisations in EU member states and Horizon Europe associated countries such as Türkiye can usually take part; the topic conditions control.

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;

Scope

The action supports research on new primitives and protocols beyond QKD for security and trust-based applications, by combining different cryptographic approaches and by exploiting insights from quantum information science, to demonstrate compelling quases of quantum cryptographic advantage and obtain foundational results on the unique features of quantum protocols. The goal is to build on the basis of insights from the field of real-world, applied cryptography and the vision from the quantum domain on future entanglement-based networks, the foundations of a new cryptography, that will support mid-term hybrid classical-quantum and further in the future almost fully quantum networks. The design of such new foundations may need entirely new paradigms whose design requires different expertise.

The proposal should target some of the following areas and lead to a roadmap:

• Development of quantum primitives which have classical equivalent, of new quantum primitives not possible classically (or without trusted hardware), and of alternative solutions improving quantum cryptography protocols using classical cryptography solutions (in particular PQC), by flexibly incorporating various cryptographic components, with some beneficial aspects such as performance improvements (run time, energy usage, less requirements on HW etc.)

Who can apply
