Quantum cryptography significantly contributes to enhancing information security systems through several practical applications. These contributions are grounded in the principles of quantum mechanics, providing unique advantages over classical cryptographic methods. 1. Unconditional Security: Quantum Key Distribution (QKD) offers unconditional security based on the laws of quantum mechanics. Unlike traditional cryptographic systems, which are vulnerable to advances in computational power, QKD's security is not compromised by future technological developments, including quantum computing advancements[2][3]. 2. Key Distribution: QKD systems facilitate secure key exchange between communication parties. Any eavesdropping attempts introduce detectable disturbances in the quantum states, thereby alerting the users of potential security breaches[1][10]. 3. Forward Secrecy: Quantum cryptographic protocols inherently support forward secrecy. This ensures that even if a private key is compromis
