Singtel plans multi-year network transformation to counter quantum threats

Singtel is taking steps to safeguard its telecom infrastructure against potential quantum threats. Kenneth Hwang, vice president of platforms and client solutions at Singtel, stated that preparing for quantum threats requires years of coordinated work across infrastructure, software, vendors, regulators, and customers. Singtel is pursuing a hybrid approach, utilizing quantum key distribution and post-quantum cryptography across different parts of the network.

The need for quantum-safe networking is being treated as an immediate network transformation challenge rather than a technology upgrade that can be postponed. This shift suggests that operators will face significant, multi-year capital expenditure to overhaul core infrastructure. Governments are also preparing for post-quantum cryptography, which may lead to new regulatory requirements.
