  Cryptography plays a pivotal role in safeguarding sensitive information and
facilitating secure communication. Classical cryptography relies on
mathematical computations, whereas quantum cryptography operates on the
principles of quantum mechanics, offering a new frontier in secure
communication. Quantum cryptographic systems introduce novel dimensions to
security, capable of detecting and thwarting eavesdropping attempts. By
contrasting quantum cryptography with its classical counterpart, it becomes
evident how quantum mechanics revolutionizes the landscape of secure
communication.
