Autonomous, AI-enabled systems will be crucial in operating enterprise networks and critical infrastructure, but their reliability and effectiveness depend on communications security. The emergence of quantum computers threatens the data integrity of corporate, military, and intelligence networks, potentially making them vulnerable to sophisticated adversaries. Advanced nation-states may attempt to compromise sensitive AI-training data exported to cloud-based GPU clusters, which could then be deployed into targeted networks and cyber-physical systems. As AI and quantum technologies rapidly advance, cybersecurity will increasingly rely on these near-future capabilities. Mitigating the risks of transferring data to AI platforms before they are obsolete is a critical first step. Quantum-secure architecture must integrate with new technologies like Nvidia DPUs to achieve higher security guarantees than typical business systems.
