Singapore is taking a bold step toward future-proofing its digital landscape with the rollout of its Singapore Quantum-Safe Infrastructure. Backed by more than S$250 million (about US$170 million) in quantum research over the past 15 years, the country is cementing its position as a regional leader in quantum technology and cybersecurity.
A Decade of Research Lays the Foundation of Singapore Quantum‑Safe Infrastructure
Much of this foundational research has been conducted through the Centre for Quantum Technologies (CQT) at the National University of Singapore. By focusing on quantum physics and translating research into practical devices, Singapore has developed a strong technical base to support this next-level infrastructure.
Singapore’s efforts are part of the broader S$300 million National Quantum Strategy (NQS), which supports four major quantum initiatives. This large-scale investment highlights the country’s commitment to developing Singapore Quantum-Safe Infrastructure and becoming a quantum technology hub in Southeast Asia.
NQSN+: Southeast Asia’s First Quantum-Safe Network
Launched in 2023, the National Quantum-Safe Network Plus (NQSN+) is Singapore’s flagship quantum-safe project. This is the first quantum-safe network infrastructure in Southeast Asia, officially announced at Asia Tech x Singapore 2023 by Deputy Prime Minister Heng Swee Keat. The NQSN+ integrates advanced technologies such as Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC), providing a powerful layer of protection for sensitive data.
These technologies are not just futuristic concepts—they are necessary safeguards against the growing quantum threat. Experts warn that quantum computers could break current encryption standards as early as the 2030s, which could expose critical data and national infrastructure to new types of cyberattacks. By investing early, Singapore is ensuring that its Singapore Quantum-Safe Infrastructure stays ahead of these emerging threats.

Singtel and NCS: Securing Enterprise Communications
At the heart of the deployment are major local players like Singtel and NCS. Together, they are rolling out Quantum Key Distribution technology across Singapore’s extensive fiber network to secure enterprise communications. This practical application of quantum-safe technology means that businesses in sectors like finance, healthcare, and critical infrastructure can now protect their most sensitive data against future attacks.
The NQSN+ makes it possible for enterprises to easily integrate quantum-safe solutions without overhauling their entire IT systems. This user-friendly approach aligns with Singapore’s Digital Connectivity Blueprint, which emphasizes strengthening digital infrastructure through innovation and public-private partnerships.
Transforming Cybersecurity Through Singapore Quantum‑Safe Infrastructure Innovation
Singapore’s deployment of Singapore Quantum-Safe Infrastructure reflects its dedication to translating research into real-world solutions. By involving both government agencies and industry leaders, the country demonstrates how collaborative models can accelerate innovation while ensuring robust cybersecurity standards.
The push toward quantum-safe communications also strengthens Singapore’s reputation as a secure and trusted hub for global businesses. Companies that rely on secure data transmission, such as banks and tech firms, will find Singapore’s proactive approach a major advantage.
