As quantum computing advances, it presents unique cybersecurity challenges that existing digital security systems are inadequately equipped to handle. This talk explores the realm of quantum cybersecurity, focusing on quantum key distribution (QKD) and post-quantum cryptography (PQC) as essential tools to secure communications against the formidable computational power of quantum computers. We will explore the advantages of these technologies, their necessity in the modern cybersecurity landscape, current interoperability issues between different quantum cryptographic systems, and propose potential solutions to these challenges. The session aims to highlight the future directions of quantum cybersecurity and the ongoing efforts to standardise and enhance the security protocols to address these emerging threats effectively.
