Following the successful [http://www.nqsn.sg National Quantum-Safe Network] Testbed trials, National Quantum-Safe Network Plus (NQSN+) was launched by IMDA in 2023 and is part of Singapore's Digital Connectivity Blueprint, which outlines the next bound of Singapore's digital connectivity to 2030. NQSN+ will support network operators to deploy quantum-safe networks nationwide, granting businesses easy access to quantum-safe solutions that safeguard their critical data. The NQSN+ will start with two network operators, Singtel and SPTel, together with SpeQtral. Each will build a nationwide, interoperable quantum-safe network that can serve all businesses. Businesses can work with NQSN+ operators to integrate quantum-safe solutions such as Quantum Key Distribution (QKD) and Post-Quantum Cryptography (PQC) and be secure in the quantum age.<ref>{{cite web | url = https://www.imda.gov.sg/about-imda/emerging-technologies-and-research/national-quantum-safe-network-plus | website = imda.gov.sg | title =  Singapore's National Quantum-Safe Network Plus (NQSN+) | first = IMDA | last = Singapore | date = 21 August 2024}}</ref>
