Quantum cryptography extends the capabilities of traditional cryptographic systems to provide secure communication based on core quantum physics notions. This paper provides a brief review of quantum cryptography approaches, focusing on quantum key distribution (QKD) protocols such as BB84 and E91. Superposition, entanglement, and the no-cloning theorem all explain quantum systems' natural ability to detect eavesdropping. The paper also examines quantum cryptography's practical applications, including scalability, limited transmission distance, channel noise, and device challenges. To emphasize their distinct advantages and disadvantages in the face of quantum computing threats, conventional, post-quantum, and quantum cryptography are contrasted. Finally, future perspectives for securely scalable quantum communication systems are discussed, including existing applications and unresolved research obstacles.
