Securing the systems of the post-quantum era.
Quantum AI Systems Security is a deep-tech venture founded and led by Professor Kai London — built where quantum computing, artificial intelligence, and cybersecurity meet. Its work is to anticipate the next generation of threat and engineer the defences that outlast it: post-quantum resilience, AI-aware security, and architectures that stay trustworthy as the technology landscape shifts beneath them.
The venture
Building security for the convergence ahead.
Quantum AI Systems Security exists for a moment few organisations are ready for: the point at which quantum computing and artificial intelligence stop being adjacent disciplines and start rewriting the rules of cybersecurity together. The venture treats that convergence not as a distant scenario but as a design constraint for the systems being built today.
Its founding premise is post-quantum resilience — the discipline of making cryptography, data, and architecture robust against adversaries armed with quantum capability and AI at scale. That means mapping where today's protections will fail, charting a path to quantum-safe foundations, and embedding security that holds as the technology underneath it keeps moving.
The work draws on Professor Kai London's standing across the field: Founder & CEO of Quantum AI Systems Security LLC, a CISO and board cyber security advisor with 25+ years across Banking, Aviation, Defence, Government, and Critical National Infrastructure, and an Honorary Professor in Cybersecurity, AI & Quantum Computing and Researcher at UCL. Research depth and operational reality, applied to the same problem.
For partners, clients, investors, and collaborators in deep-tech security, the invitation is simple: build the defences of the next era before its threats arrive.
Foundations & standing
Grounded in the standards that matter.
The venture's work sits on a rigorous base of security, AI-governance, and resilience frameworks — credentials and standards held by its founder and applied across every engagement.
Areas of focus
Where the venture concentrates its work.
Six domains at the heart of post-quantum, AI-aware security — each chosen because the threat is arriving faster than most defences are evolving.
Post-Quantum Resilience
Readying cryptography, data, and architecture for a world with quantum-capable adversaries — before the migration becomes urgent.
Quantum-Safe Cryptography
Identifying quantum-vulnerable protections and charting the path to standards-aligned, quantum-safe foundations.
AI Security & Governance
Securing AI systems and governing them responsibly — aligned to the EU AI Act and ISO 42001 — so capability and trust grow together.
Zero Trust Architecture
Designing to NIST 800-207 principles, with verification and least privilege built into systems facing a more capable threat.
Operational Resilience
Engineering for continuity and recovery so critical systems hold steady as the technology landscape shifts beneath them.
Next-Generation Innovation
Research-led exploration at the quantum, AI, and cyber frontier — turning emerging science into defensible security.
The organisations that thrive through the quantum and AI transition will be the ones that started securing for it early — engineering resilience as a foundation, not retrofitting it under pressure.
Leadership
The experience behind the venture.
Quantum AI Systems Security is led by a founder whose career spans research, the boardroom, and the operational front line of cyber security.
