Quantum Computing Solutions

Quantum Computing Solutions (QCS) is a European deep-tech company specialised in post-quantum cryptography (PQC) and resilient digital infrastructure for long-term protection of critical information.

QCS focuses on the development of sovereign, cryptographically self-contained systems designed to withstand emerging quantum threats and high-adversarial environments. Our work addresses one of the most pressing challenges in cybersecurity today: ensuring the integrity, confidentiality and verifiability of digital assets in a post-quantum era.

Our core technology enables the creation of autonomous cryptographic containers that combine hybrid post-quantum encryption (Kyber-based key encapsulation) and quantum-resistant digital signatures (Dilithium) within a deterministic and verifiable architecture. These containers are designed to operate without dependency on external PKI infrastructures, enabling offline verification and long-term resilience.

QCS technologies are particularly relevant in dual-use environments where secure preservation, transmission and verification of digital assets are mission-critical. Applications include:

• Defence and military documentation
• Secure archival of classified or sensitive material
• Critical infrastructure and energy systems
• Justice and institutional evidence preservation
• Aerospace and industrial intellectual property protection
