# South Korean AI and quantum security development > Live situation record from CLSTR: https://clstr.news/situations/south-korean-ai-and-quantum-security-development > Updated: 2026-09-22T01:20:00.000Z. Sources: 2. Developments: 2. South Korean entities are advancing the integration of artificial intelligence and quantum security technologies across various sectors. Initially, SK Broadband, SK Telecom, and the Korea Social Security Information Service established a partnership to modernize social security services. This collaboration focuses on using AI and telecommunications data to identify households in welfare crises, while implementing Post-Quantum Cryptography (PQC) and quantum communication to protect sensitive data within cloud environments. Furthering these technological capabilities, SK Telecom and the Korea Institute of Science and Technology Information (KISTI) developed a digital twin approach to simulate quantum cryptography networks. This technology allows for the real-time verification of Quantum Key Distribution (QKD) performance and interoperability using international standards, reducing the need for physical testing on expensive hardware and supporting the broader commercialization of quantum networks. ## Timeline ### 2026-09-22: SK Telecom and KISTI develop quantum cryptography network simulation technology SK Telecom and KISTI have developed a digital twin technology to simulate and verify quantum cryptography networks in virtual environments using international standards. 2 sources. https://clstr.news/cluster/sk-telecom-and-kisti-develop-quantum-cryptography-network-simulation-technology ### 2026-09-14: SK Broadband and partners to innovate welfare services with AI and quantum security SK Broadband, SK Telecom, and the Korea Social Security Information Service are partnering to integrate AI, quantum-resistant cryptography, and cloud technology into digital welfare services. 2 sources. https://clstr.news/cluster/sk-broadband-and-partners-to-innovate-welfare-services-with-ai-and-quantum-security --- Cite as: South Korean AI and quantum security development.
