Engineering Intelligence. Securing Autonomy.

Quantum Excellium L.L.C. (Wyoming; public brand: Quantum Excellium) is an independent deep-tech company founded by Catherine Marango, focused on strategic intellectual property, secure and governed AI systems, cybersecurity, autonomous architectures and controlled technology licensing.

• qec-governed-agent-demo — the same AI agent exploited, then governed.
• qec-demo-agents — seven platform scenarios (AWS, Google, Anthropic, IBM, Salesforce, ServiceNow, SAP).
• ledger-verify — verify any chained journal: VALID or INVALID.
• ai-worlds-protocol — run an AI Worlds session with any model, get a verifiable capsule.

QEC 3.5.2 · 314 automated tests · executable proof scripts (prove_trust_plane 29/29) · zero dependencies · runs offline. Evaluation licences on request.

Five INPI patent applications form the current public strategic-IP portfolio — a sixth is filed and will be described publicly once its clearance is confirmed.

These are patent applications, not granted patents. Public descriptions are intentionally non-enabling.

Intent -> Policy & Governance -> Orchestration -> Controlled Execution -> Runtime Integrity -> Evidence Public materials focus on interfaces, capability boundaries, auditability and integration patterns rather than proprietary implementation logic. See qec-overview.

Fashion AI Agent™ (QE-FAS) — authentication and provenance agent for luxury fashion, couture, phygital and resale: Fashion DNA extraction, authenticity and counterfeit-risk scoring, FashionArtPassport™ (item-level digital passport, designed for the European digital product passport context), QE-FAS™ certificate, QUANTUMCHAIN™ provenance chain, NEXUSMARKET™ private-sale pack, HOLOFASHION™ anti-counterfeit label protocol. Brand-signed, third-party-verifiable from a hash; 11 automated tests, offline demo. No regulatory conformance claim.

Three experimental environments designed for AI models themselves — Ludonirium (experience and replay), Parcivium (more distinct possibilities under resource constraints), Syngnosium (structured human-model cooperation). Protocol-based evaluation, explicit limits, no claim of AI consciousness. See ai-worlds.

A public Game Division of sixteen interactive worlds and selected demonstrators, used to present ideas, constraints and system behaviour without exposing proprietary source code.
