Keywords:
Quantum Cryptography, Secure Communication, Quantum Key Distribution (QKD), BB84 Protocol, E91 Protocol, Quantum Properties, Superposition, Entanglement, Unauthorized Interception, Cyber Threats, Research Advancements, Challenges, Future DirectionsAbstract
Quantum cryptography is a cutting-edge technology that offers unparalleled levels of security in communication protocols by using the principles of quantum mechanics. This article delves into the fundamental concepts that underlie quantum cryptography, such as quantum key distribution (QKD) protocols like BB84 and E91, and their application in achieving secure communication channels. By leveraging quantum properties like superposition and entanglement, quantum cryptography ensures the detection of any unauthorized interception of information, providing a theoretically unbreakable method for secure communication. The article also discusses the current state of quantum cryptography research, including advancements, challenges, and potential future directions, highlighting its critical role in addressing the security concerns of modern communication systems in a time of escalating cyber threats.
