Abstract

Quantum cryptography has emerged as one of the most promising fields in modern information security, offering innovative solutions that have the potential to transform the future of global cyber-defense. Unlike classical cryptographic systems, which depend primarily on the computational difficulty of solving complex mathematical problems, quantum cryptography is grounded in the fundamental and unbreakable laws of quantum mechanics. Core principles such as superposition, entanglement, and the uncertainty principle form the foundation of this science, providing unprecedented levels of security that cannot be replicated by conventional approaches. This study presents a detailed overview of essential methods within quantum cryptography, with particular emphasis on Quantum Key Distribution (QKD), post-quantum or quantum-resistant algorithms, and their importance in securing communication networks against increasingly sophisticated threats. Furthermore, real-world applications and current experimental advancements are examined, demonstrating the growing practicality of these technologies. The study also discusses the significant challenges that must be addressed before widespread implementation, including technical, economic, and infrastructural barriers. By combining theoretical insights with experimental progress, this study highlights the critical role quantum cryptography is expected to play in ensuring the resilience of modern communication systems.

Keywords: Quantum cryptography, quantum key distribution, post-quantum algorithms, secure networks, quantum communication systems
