Singtel treats quantum-safe networking as a long-term migration effort
Singtel is approaching quantum security as a network transformation effort that requires coordination among operators, vendors, regulators, and customers. Executive Kenneth Hwang said telecom infrastructure and cryptographic systems have long lifecycles, so planning cannot wait for commercial quantum computers. The operator is pursuing a hybrid approach that combines quantum key distribution and post-quantum cryptography across different parts of its network.
Kenneth Hwang, a Singtel platforms and client solutions executive, frames quantum readiness as a multiyear network migration. Because mobile generations and passive optical networks often operate for a decade or longer, cryptographic upgrades must be planned before commercial quantum machines arrive. Singtel's early work spans many domains, from optical transport and mobile core to cloud, APIs, billing, and IoT.
The company favors combining quantum key distribution with post-quantum cryptography in different network areas. It has collaborated with Singapore's IMDA, the Center for Quantum Technologies, vendors, researchers, and industry partners. Singapore's national quantum-safe network initiative showed QKD across telecom infrastructure; its next phase emphasizes interoperability, commercial deployment, and business adoption.
Quantum-safe migration may affect banks, hospitals, government agencies, cloud users, and IoT operators that rely on telecom networks. If carriers plan early, sensitive data could remain protected through long infrastructure cycles; delays may create uneven readiness across providers and regions. Enterprises and consumers might see costs or service changes as operators upgrade cryptography, while coordinated standards could improve trust in digital services.
