Quantum Cyber: The Next Frontier in Enterprise AI Infrastructure Security

## Executive Summary The article warns that adversaries are harvesting AI training data and model weights now to decrypt later once quantum capabilities mature (HNDL), identifies the Model Context Protocol (MCP) as a high-risk attack surface (stdio-based command/command-injection risk), and recommends moving to data-level zero trust with hybrid post-quantum cryptography, continuous MCP auditing, and AI-driven real-time defenses to protect long-lived AI assets and comply with emerging procurement standards.
