Applied Quantum is the first professional services firm dedicated to quantum technologies across computing, communications, sensing, and simulation. We deliver quantum-focused end-to-end advisory, R&D, and systems integration.

On the security front we execute cryptographic inventories and cryptographic bills of materials (CBOMs), build enterprise crypto agility, plan and deliver PQC migrations and hybrid patterns, and design quantum safe networks (including QKD where warranted), with governance and compliance built in.

The result is a de-risked path from exploration to business outcomes – without hype or lock in.
