Post-Quantum Transition Advisory and Secure Architecture Design for Defence and Critical Infrastructure

Quantum Computing Solutions (QCS) provides specialised advisory and technical services supporting organisations in the transition to post-quantum cryptography (PQC) and the design of resilient digital infrastructures for high-security environments.

Our services focus on helping defence actors, public institutions and critical infrastructure operators assess quantum-related risks and implement structured, standards-aligned migration strategies.

We support organisations in:

• Post-quantum risk assessment and cryptographic inventory mapping
• Design of hybrid and quantum-resistant cryptographic architectures
• Secure document and digital asset protection frameworks
• Integration of PQC primitives (Kyber, Dilithium) in existing systems
• Definition of long-term digital preservation strategies resilient to “harvest now, decrypt later” threats
• Evaluation of PKI dependencies and offline-verifiable alternatives
• Secure integration with HSMs, TPMs and hardware security environments

Our approach combines applied cryptographic expertise with practical system integration knowledge, enabling structured migration pathways that balance operational continuity with long-term resilience.

We are open to participating in consortium-based R&D projects, technical work packages focused on post-quantum transition, and strategic advisory roles within defence-oriented digital infrastructure programmes.
