Quantum Cyber Security Strategies for Enterprise AI: A Practical Roadmap

This blog-style advisory warns that adversaries are harvesting encrypted AI pipeline traffic now with the expectation that future quantum-capable computers will enable decryption (the "Harvest Now, Decrypt Later" threat). It highlights the Model Context Protocol (MCP) as an expanded attack surface, outlines a four-phase roadmap—data mapping, cryptographic agility (hybrid/PQC), Zero-Trust hardening for MCP, and AI-driven behavioral analysis—and urges CISOs to prioritize quantum-resistant defenses and policy-driven, least-privilege access for AI agents.
