Securing the Future of Communication with Quantum Cryptography

The study of quantum cryptography has become a ray of hope in the constantly changing field of cybersecurity. Quantum cryptography uses the remarkable qualities of quantum mechanics to provide a level of security that classical cryptography finds difficult to achieve in light of the growing threats to digital information. This thorough analysis explores the many facets of quantum cryptography, including emerging quantum networks, practical applications, cryptographic protocols, and basic concepts. This review explains the intricacies of cost, infrastructure, and integration, and compares them with the continuous technological developments that indicate that it is ready for broad adoption. The impending threat of quantum computers, which calls for a switch to quantum-safe cryptography, looms large amid the promise of quantum security. Quantum-safe algorithms are important because they provide strong security against quantum attacks.
