Harnessing Quantum Cryptography for Future-Proofing Secure Communication Protocols in High-Sensitivity Applications

Abstract

The advent of quantum computing threatens conventional cryptographic techniques, creating an urgent demand for quantum-resistant solutions. Quantum cryptography, particularly Quantum Key Distribution (QKD), emerges as a promising technology to secure high-sensitivity communication protocols. This paper explores the theoretical foundations, existing implementations, and potential advancements in quantum cryptography. Through a detailed literature review and analysis, this study highlights the viability of quantum cryptography for safeguarding sensitive data in critical sectors, such as finance and defense.
