NQSN Singapore: Quantum-Safe Network Testbed with Versatile Reference Applications
summary
Nationwide star-topology testbed runs on production fiber with 1,500 km fiber and more than 75 dark fibers connecting about 12 nodes, supporting multi-vendor QKD (ID Quantique, Toshiba, Quintessence Labs, S‑Fifteen, plus an in‑house entangled system) and hybrid PQC integration. A centralized key and network management layer uses TLS 1.3 and S25519 hybrid ML‑KEM‑768 with ETSI 014 compliance, delivers kilohundreds kbps key rates over 0.5–45 km links, and exposes a public randomness beacon for reference applications.
