The third edition of the QSNS Workshop is jointly organised by the SPQR cluster projects: QUBIP, PQ-REACT, PQ-NEXT, POSEIDON, QARC, and Q-FENCE. The projects are co-funded by the European Union under the Horizon Europe framework programme and focus on advancing the transition of protocols, networks, and systems toward Post-Quantum Cryptography (PQC).

The QSNS 2026 workshop will address the most pressing cybersecurity challenges of the quantum era from an engineering perspective, with the aim of contributing to global efforts toward an agile, post-quantum or post-quantum/traditional hybrid, standards-based transition to PQC for the digital infrastructures we all use today.
