Explore Singapore's National Quantum-Safe Network (NQSN) through this 24-minute conference presentation that details the strategic vision and technical foundations of a resilient, fully interoperable quantum-safe testbed. Learn about the network's production-grade fiber infrastructure built in a star-topology layout that supports multi-protocol quantum key distribution (QKD) from multiple vendors. Discover how a centralized key and network management system ensures interoperability and enables seamless integration across heterogeneous quantum and classical technologies. Examine diverse reference applications including data center interconnects, edge computing, hybrid QKD–post-quantum cryptography (PQC) encryption, and multi-layer security across the OSI stack. Understand how these implementations demonstrate the feasibility, adaptability, and real-world relevance of deploying quantum-safe technologies in complex network environments, providing valuable insights for organizations preparing for the quantum computing era.
