Namirial strengthens its European leadership in post-quantum security through a practical demonstration of quantum computing and cryptographic developments compliant with NIST standards.
Milan, Paris, Barcelona, February 9, 2026 – Namirial, a leading European provider of digital trust and digital transaction management solutions, announces the completion of the first practical demonstration of quantum computing applied to digital security. This demonstration consisted of factoring an RSA key (the foundation of systems currently protecting digital communications) on an operational quantum computer. This is the first concrete demonstration of its kind in the digital trust sector, highlighting the real impact of quantum technologies on the cryptographic mechanisms currently deployed.
This initiative is part of the company’s long-term strategy to anticipate the effects of quantum computing on cryptography and to support European businesses and institutions in their transition towards quantum-resistant digital solutions, in line with the standardisation roadmaps defined by the National Institute of Standards and Technology (NIST) and the recommendations of European authorities.
Details of the experiment
Factoring an RSA key using an operational quantum computer would ultimately allow the rapid decomposition of the numbers underpinning current cryptography, rendering many protection systems currently in use vulnerable.
Namirial’s Innovation team performed the factorisation of the number 15 (3×5), equivalent to a 4-bit RSA key, using a quantum circuit executed on AWS Braket. The computation time was approximately 4 seconds. Although this is a small-scale demonstration, the experiment is of particular significance as it was conducted on real quantum infrastructure. It confirms Namirial’s ability to leverage advanced architectures and translate scientific research into concrete industrial expertise.
A trajectory consistent with European and NIST strategies
This result is part of a structured programme for developing post-quantum security architectures and systems, in which Namirial is engaged across several complementary areas:
Contributing to the development of a hybrid network architecture integrating Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC) algorithms, in collaboration with the Federico II University of Naples and the MedITech competence centre;
Analysing the performance of Post-Quantum Cryptography (PQC) algorithms in secure environments, the results of which were presented at the sixth NIST conference on post-quantum algorithm standardisation, held in Washington (United States) in 2025.
This approach enables Namirial to align technological innovation with future regulatory frameworks and compliance requirements, while actively contributing to the construction of a resilient European digital ecosystem in the face of the emergence of quantum computing.
Why this is a strategic result
This demonstration does not constitute an attack on modern RSA systems, but anticipates future scenarios already taken into account by NIST, ENISA and European institutions. It also confirms the need to begin adopting quantum-resistant digital signatures based on NIST standards now, and reinforces Namirial’s positioning as a leading European player at the intersection of digital security, international standards and emerging technologies.
“The transition to post-quantum is not a distant prospect, but an immediate responsibility for players in digital security. This demonstration confirms Namirial’s ability to work with real quantum technologies and to align innovation with NIST standards and European cyber-resilience strategies.” Davide Coletto, CIO & CAIO
