Today, Singapore is building the future of secure communication. With the launch of the National Quantum-Safe Network Plus (NQSN+) in 2023, the country is taking major steps to protect businesses and critical sectors from the coming risks of quantum computing. This nationwide initiative marks a major milestone in the development of the Singapore Quantum-Safe Network, integrating over a decade of research with cutting-edge infrastructure and real-world enterprise solutions. Let's talk more about this!
Singapore Quantum-Safe Network: A Decade of Research, A National Rollout
The NQSN+ initiative is not just a tech upgrade—it’s part of Singapore’s Digital Connectivity Blueprint. It leverages over 10 years of quantum research by the Centre for Quantum Technologies and involves multiple network providers including Singtel, SPTel, and SpeQtral. Together, they’re rolling out a nationwide, interoperable quantum-safe network. Technologies like Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC) are at the core, enabling businesses to adopt future-proof security protocols now.

Singapore Quantum-Safe Network: Award-Winning Innovation by SPTel
SPTel’s deployment of its quantum-safe network has not gone unnoticed. In 2025, it won two awards at the Asian Telecom Awards for Network and Security Integration and Technology Innovation. The network features physically separate fibre lines and ultra-low latency (<1ms), making it ideal for quantum key transmission. This makes SPTel’s infrastructure both resilient and scalable for high-security applications like banking and government services.
Banks Step In: MAS and the Financial Sector Join the Push
Security isn’t just a telecom concern—it’s a financial one too. In 2024, the Monetary Authority of Singapore (MAS) and top banks including DBS, HSBC, OCBC, and UOB signed an MoU with SPTel and SpeQtral. The goal? To explore and deploy QKD within financial services, ensuring that cryptographic communications stay secure even as quantum computers advance.
This sector-wide collaboration is proof of the growing urgency. As quantum capabilities mature, traditional encryption methods may be at risk. The financial industry, which depends heavily on secure data, is preparing now—not later.
Singtel and NCS: Leading Southeast Asia’s Quantum-Safe Effort
Singtel is pioneering Southeast Asia’s first nationwide quantum-safe network, playing a central role in the NQSN+. Appointed by Singapore’s Infocomm Media Development Authority (IMDA), Singtel is offering enterprise trial programs that let businesses test-drive quantum-safe technologies before committing to adoption.
Its infrastructure supports a broad range of network and security devices, extending protection to identity, mobility, and authentication services. With NCS as its tech partner, Singtel is not just deploying hardware—it’s enabling a full-stack security transformation for businesses in finance, healthcare, and beyond.
Building Trust Before the Threat Arrives with Singapore Quantum-Safe Network
The Singapore Quantum-Safe Network isn’t a reaction, but a proactive defense. From enterprise trials to national-scale fiber upgrades, Singapore is preparing its digital economy for the quantum era. With collaboration from government, telecoms, banks, and research institutions, the country is laying the groundwork for a future where data stays secure, even in the face of quantum computing’s immense power. For the rest of the world, Singapore offers a clear message: the time to act on quantum security is now.
