Quantum Cryptography for Secure Wireless Communication

Abstract

Through the application of principles from quantum physics, quantum cryptography is a cutting-edge technology that offers unparalleled protection for communication protocols. The fundamental concepts of quantum cryptography are discussed in this article. These principles include quantum key distribution (QKD) protocols like BB84 and E91, as well as their use in the process of constructing secure communication channels to ensure confidentiality. For the purpose of detecting any unlawful interception of information, quantum cryptography makes use of quantum properties such as superposition and entanglement. This provides a technique of secure communication that has the potential to be unbreakable. The research investigates the current state of quantum cryptography research, which includes recent advancements, challenges, and potential future directions. The study highlights the critical significance of quantum cryptography in addressing security concerns within modern communication networks in the face of increasing cyber threats.
