Exploring the Potential of Quantum Key Distribution (QKD) in Secure Communication

Abstract

In today's evolving communication scenery, ensuring data security is vital. A viable remedy is provided by quantum cryptography, which uses quantum mechanics to create communication channels that are intrinsically secure. This paper clarifies the theoretical underpinnings and real-world applications of quantum cryptography through an extensive review of the literature. Key concept such as Quantum Key Distribution (QKD) is analysed to assess their effectiveness. QKD ensures unbreakable encryption by utilizing quantum principles to distribute keys. With its exceptional ability to withstand eavesdropping attacks, QKD provides secure channels that can span great distances. The development of quantum-resistant encryption algorithms is being aided by the advancement of practical implementations. Furthermore, the paper also highlights issues and unanswered research questions regarding implications of QKD for secure communication.
