Quantum Shield closes 2025 with major advances for post-quantum security in Industry 4.0
The Quantum Shield project developed by the AIR Institute has consolidated its development throughout 2025. Thanks to the support of the Institute for Business Competitiveness of the Regional Government of Castile and Leon (ICECYL) and the European Regional Development Fund (ERDF), we are setting a precedent in post-quantum security and cybersecurity in Industry 4.0.
Over the past year, the team has contributed to knowledge transfer, scientific research, and technological validation by participating in leading national and international forums. Noteworthy actions include training on the quantum threat and Shor's algorithm during CyberChain Chair Cybersecurity Week, as well as the publication of the scientific article “Quantum Technologies and Cybersecurity in Economy and Industry: A Review and Key Challenges,” presented at ISAmI and published by Springer.
We have also boosted the visibility of the project, with appearances in media outlets such as El Mundo – Premios Innovadores 2025, showcasing how we are working in Salamanca on post-quantum cryptography, quantum key distribution, and quantum machine learning applied to strategic sectors such as industry, banking, and healthcare.

One of the major milestones of the year has been access to real quantum infrastructures of the Spanish Supercomputing Network (RES), allowing us to advance in the implementation of the Regev algorithm and validate solutions in quantum hardware from CESGA and BSC.
In addition, Quantum Shield has been present at events such as the QUINCY Special Session at DCAI25 (Lille), the RES User Conference, the CSDT project Summer School, and various academic presentations, reinforcing its position as a benchmark project in quantum computing applied to cybersecurity and industry.
It has been a year of progress, new partnerships, and the coming together of all the pieces to continue advancing toward the project's goals.
