Quantum Key Distribution (QKD) and Secure Communication

This specialized training delves into the principles and implementation of Quantum Key Distribution (QKD)—a foundational technology for future-proof secure communication systems. As classical cryptography faces potential threats from quantum computing, QKD offers a quantum-safe solution by leveraging the laws of quantum mechanics to ensure provable security in key exchange. Participants will explore the theoretical underpinnings of QKD protocols (such as BB84 and decoy-state methods), the architecture of QKD systems, and practical considerations in both fiber-based and free-space quantum communication. The course also covers integration of QKD with classical networks, system performance metrics like QBER and SKR, and recent advances including satellite-based QKD, measurement-device-independent QKD, and continuous-variable QKD.This specialized training delves into the principles and implementation of Quantum Key Distribution (QKD)—a foundational technology for future-proof secure communication systems.
