Terra Quantum AG has successfully deployed a live post-quantum secure optical network link in Malta, utilizing its proprietary Quantum Key Distribution (QKD) hardware platform. This deployment, executed in collaboration with Merqury Cybersecurity and Melita Business, establishes a secure data link between two primary commercial data centers. The implementation demonstrates the feasibility of post-quantum secure communication over production-grade telecommunications networks. By integrating QKD technology, the network link ensures the secure exchange of sensitive information, mitigating the risk of quantum computer-based attacks. This development underscores the growing urgency for organizations to migrate to post-quantum cryptography (PQC)1, as the timeline for cryptographic migration narrows. The successful deployment in Malta serves as a significant milestone in the advancement of quantum-secure communication, emphasizing the need for practitioners to prioritize PQC planning to ensure the long-term security of their data.
