 The Quantum Key Distribution Market (QKD) focuses on technologies that allow ultra-secure communication using quantum mechanics to encrypt and share cryptographic keys. Unlike traditional encryption, which is based on complex algorithms, QKD ensures that any attempt at interception instantly alters the quantum state, making violation detectable. This has positioned QKD as a critical component in next-generation cybersecurity, especially in sectors such as defence, finance and critical infrastructure. As global concerns about cyber threats and the impact of quantum computing on current encryption systems grow, organizations and governments are increasingly exploiting QKD solutions to prove their data security frameworks.
