Quantum computing promises extraordinary progress — much faster data processing and the ability to solve complex problems that are impossible today. But this power comes with a price.
The same technology that could transform the way we process and use data also threatens to undermine the systems that keep this data secure. Once quantum computers become powerful enough, many of today’s encryption methods will no longer be effective. This creates a new risk: data stolen today could be decrypted in the future — exposing sensitive information, financial systems, and even national infrastructures.
These risks extend far beyond data alone — they also threaten the foundations of European digital identity and the systems that manage it. Strengthening our ability to secure digital identity securely is therefore crucial to safeguarding citizens, services, and institutions in the post-quantum era.
To address these challenges, the POSEIDON project has been launched as a European initiative dedicated to strengthening digital security in the post-quantum era. POSEIDON focuses on the development and deployment of post-quantum cryptographic solutions designed to safeguard digital identity and sensitive data against emerging quantum threats.
