Document Introduction

The U.S. Department of Homeland Security (DHS), as the third-largest cabinet department in the federal government, integrates multiple agencies such as the Federal Emergency Management Agency (FEMA), the Office for Countering Weapons of Mass Destruction, and the United States Coast Guard (USCG). It undertakes diverse core missions including counterterrorism, border security, cyberspace protection, economic security assurance, and disaster preparedness. Faced with an increasingly complex security environment and massive data processing demands, traditional technologies can no longer adequately meet the urgent needs for efficient performance of duties. Artificial Intelligence (AI) and Quantum Computing (QC), as two major emerging disruptive technologies, offer new possibilities for enhancing homeland security mission capabilities.

This report systematically reviews the technical characteristics, development status, and integration potential of quantum computing and artificial intelligence. Artificial Intelligence, particularly its machine learning branch, has been maturely applied in various fields due to its ability to process massive data and rapidly optimize decisions. Quantum computing, leveraging quantum mechanical principles such as superposition and entanglement, possesses potential advantages over classical computing in handling complex optimization problems, code-breaking, and encryption. The report specifically points out that Quantum Machine Learning (QML), as an interdisciplinary field, although currently facing technical challenges such as data loading and hardware noise, has demonstrated unique value like quadratic speedup in specific task scenarios.

Using the six core missions of the U.S. Department of Homeland Security as a framework, the report analyzes the application scenarios of AI and quantum computing one by one. In the field of counterterrorism, quantum optimization algorithms can enhance intelligence screening efficiency and threat identification accuracy. In border security, they can empower autonomous drone patrols, resource deployment optimization, and immigration fraud detection. In the cybersecurity domain, Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC) provide solutions to address the encryption threats posed by quantum computing, while quantum algorithms may also be used to launch new types of cyberattacks. In disaster preparedness and resilience building, quantum computing can optimize weather prediction models and disaster response resource scheduling.

Based on solid literature review, technical analysis, and professional expertise, the report clarifies the key constraints of current technology applications, including quantum hardware noise issues, technical bottlenecks in data loading, and the adaptability of algorithms to practical tasks. Simultaneously, regarding how DHS can seize technological opportunities, it proposes three major strategic recommendations: establishing an internal quantum technology team, outsourcing quantum needs, and monitoring technological progress while cultivating talent. These provide a core reference for the department in formulating a technology development roadmap.

The research findings of this report extend beyond the level of technology application. They emphasize that within the context of public-private sector collaboration in advancing quantum technology R&D, the Department of Homeland Security does not need to become a core developer but should, through strategic positioning, adopt a pragmatic path to become an early beneficiary. This provides a rigorous analytical framework for balancing technological potential with real-world constraints.
