ABSTRACT:

Quantum Key Distribution (QKD) stands as a revolutionary paradigm in secure communication, leveraging the principles of quantum mechanics to establish cryptographic keys with unprecedented levels of security. This paper explores the foundational concepts and key protocols of QKD, emphasizing its role in addressing the vulnerabilities associated with classical key exchange methods. The discussion covers quantum entanglement, quantum superposition, and the no-cloning theorem as the cornerstones of QKD. Furthermore, the abstract delves into the practical implementations and challenges, highlighting the potential of QKD to redefine the landscape of secure communication in an increasingly interconnected world.

Key words: Quantum Key Distribution, Quantum communication, quantum entanglement, cryptographic security, no-cloning theorem, secure communication, unbreakable security, quantum technology.
