Singapore today launched the National Quantum-Safe Network Plus (NQSN+), as part of its Digital Connectivity Blueprint.
Quantum computers use principles of quantum physics to solve problems too complex for classical computers. They will also unlock unprecedented advancements in raw computing power, simulation and optimisation with the potential to revolutionise industries and spur innovation.
Yet, quantum computers can introduce new security risks as they can break many encryption algorithms that we rely on today.
As such, the NQSN+ will support network operators to deploy quantum-safe networks that can help businesses safeguard their critical data.
The NQSN+ will start with at least two network operators, with each building a nationwide, interoperable quantum-safe network that can serve all businesses. Businesses can work with the NQSN+ operators to integrate quantum-safe solutions to safeguard their critical data and information in the quantum age.
The Infocomm Media Development Authority (IMDA) is currently evaluating proposals from Singtel, and from a joint partnership between SPTel and SpeQtral.

Domestic and international collaboration
Singapore aims to integrate NQSN+ with quantum-safe networks of other cities to enable local enterprises to build and deploy quantum-safe solutions across global markets.
To kickstart that, IMDA has signed a memorandum of understanding with the Republic of Korea’s National Information Society Agency to collaborate on quantum technologies and standardisation efforts. This collaboration will also facilitate the exchange of learnings and experiences between the network operators in their implementation of quantum-safe networks.

Besides that, IMDA and the NQSN team are also driving international and local standardisation of quantum-safe technologies. This includes quantum key distribution (QKD), which is a secure communication method for exchanging encryption keys only known between shared parties.
Together with Japan, Singapore will co-lead the first standardisation of the QKD protocol framework at the ITU Telecommunication Standardisation Sector (ITU-T).
Domestically, the city-state has published the first Reference Specification (RS) on QKD Networks to guide technology vendors and organisations keen to deploy QKD networks.
These efforts would serve to promote the deployment of QKD networks, thereby fostering the adoption of quantum security both nationally and globally.
