Quantum Bridge raises €7.4M Series A for quantum-secure cryptography

Quantum Bridge banked €7.4M ($8M) Series A funding to scale its cryptographic solutions designed to resist quantum computing attacks. This all-equity round was led by Primo Capital, providing the Italian firm with the capital necessary to expand its technical team and commercial reach across Europe.

The company develops "quantum-secure" technologies, specifically focused on Key Management Systems and Symmetric Key Distribution. Unlike traditional encryption that may be vulnerable to future quantum processors, Quantum Bridge provides a proprietary architecture that ensures end-to-end data protection for high-stakes environments. Its primary clients operate in the finance, government, and defence sectors, where long-term data confidentiality is a regulatory requirement.

Based in Italy, the startup addresses the "Harvest Now, Decrypt Later" threat, where malicious actors collect encrypted data today with the intent of unlocking it once quantum hardware matures. The funding follows initial research and development phases aimed at integrating these security layers into existing network infrastructures without requiring a total hardware overhaul.

As European sovereignty becomes a central pillar of the continent's tech policy, investment is increasingly shifting toward "deep tech" infrastructure that secures critical state and financial assets against emerging computational threats.
