SPTel, SpeQtral to build SG's first nationwide quantum-safe network

The network will use quantum cryptography to achieve unprecedented levels of security.

The Infocomm Media Development Authority of Singapore (IMDA) has tapped SPTel, ST Engineering and SP Group's joint venture, and SpeQtral to build the National Quantum-Safe Network Plus (NQSN+).

NQSN+ is an interoperable network fortified with quantum encryption capabilities. It will provide data protection for critical government and commercial applications.

NQSN+ will utilise quantum cryptography to ensure secure transmission of sensitive information and enhance security against cryptographic attacks.

The award of the NQSN+ project builds on SPTel and SpeQtral's successful trials in quantum-secure networks on the former's diverse fibre network in 2022.
