Singapore’s Cyber Security Agency (CSA) released a Quantum-Safe Handbook and Quantum Readiness Index (QRI) on October 22, 2025, announced by Minister for Digital Development and Information Josephine Teo at the Singapore International Cyber Week, according to the CSA press release.
The Quantum-Safe Handbook provides guidance for organizations, particularly Critical Information Infrastructure (CII) owners and government agencies, in preparing for the quantum-safe transition. It was jointly developed by CSA, the Government Technology Agency of Singapore (GovTech), and IMDA, in collaboration with leading technology companies, cybersecurity consultancies, and professional associations.
Both documents were released for public consultation from October 23 to December 31, 2025. CSA noted that while the timeline for the quantum threat remains uncertain, organizations should start preparing and planning for quantum-safe migration as soon as practically possible, given that the transition is likely to be a complex and multi-year effort.
