Singapore’s Cyber Security Agency has introduced two significant resources aimed at helping organizations prepare for risks linked to future quantum computing capabilities. The initiative includes a Quantum Safe Handbook and a Quantum Readiness Index, both designed to support critical infrastructure operators, government agencies and technology reliant sectors in evaluating their exposure to quantum related threats. The documents were released in collaboration with GovTech Singapore, Infocomm Media Development Authority and several technology partners, marking an expanded effort to equip institutions with guidance for managing the complex shift toward quantum safe cryptography.
The handbook outlines what is widely described as the quantum threat, referring to the potential for highly advanced quantum computers to weaken or break current cryptographic systems that protect global digital environments. These systems form the basis of secure communication, online financial transactions, identity verification and various layers of authentication across public and private platforms. While no precise forecast exists for when an operational quantum system capable of undermining present encryption standards might emerge, the agency highlights that the transition to quantum safe methods is expected to span multiple years. This timeframe requires organizations to begin planning early, evaluate their dependence on existing cryptographic tools and coordinate efforts across internal teams as well as external partners. The agency noted that the exact arrival of what is often described as Q day cannot be predicted with accuracy, emphasizing the need for methodical preparation rather than reactive change.
Alongside the handbook, the Quantum Readiness Index functions as a structured self assessment tool that allows organizations to measure their preparedness levels and understand where they stand in relation to quantum safe adoption. The index is intended to help decision makers identify processes, systems and communication channels that rely on vulnerable cryptographic standards. It also encourages institutions to prioritize actions based on risk exposure, operational impact and resource availability. Through this approach, organizations can build a clearer roadmap for upgrading cryptographic components, managing legacy environments and strengthening long term data security. The index is designed to be flexible so a wide range of sectors can adapt it to their specific operational needs.
Both resources incorporate principles previously outlined in the World Economic Forum publication titled Quantum Readiness Toolkit: Building a Quantum Secure Economy from 2023. That document called for international cooperation, cross border collaboration and synchronized policy development to address quantum risks collectively. It also proposed a structured model that organizations can use to gauge their quantum preparedness, assess current vulnerabilities and implement improvements gradually. Singapore’s new resources mirror this direction by presenting a unified structure that encourages coordinated progress rather than isolated adoption.
The Quantum Safe Handbook and Quantum Readiness Index are currently open for public consultation until 31 December 2025. Stakeholders from industry, government and academia are invited to provide feedback that may support the refinement of these resources as Singapore continues to strengthen its long term cybersecurity posture.
