Quantum Entanglement and Its Applications in Modern Cryptography

Abstract

A lot of people have been interested in quantum entanglement recently, especially because of the possible uses it could have in contemporary encryption. It's the phenomena wherein quantum particles stay connected no matter how far apart they are. the principles and applications of quantum entanglement in creating safe protocols for data transmission. The most visible use of quantum entanglement is quantum key distribution (QKD), a quantum mechanically based approach to secure information exchange. Concepts of QKD, with an emphasis on important protocols like BB84 and E91 that use entanglement to generate cryptographically sound keys. Our investigation also delves into quantum teleportation and how it could be incorporated into forthcoming encryption protocols. We also go into the pros and cons of using quantum entanglement in practical cryptographic contexts, including topics like quantum channel security, noise mitigation, and the necessity of quantum repeaters. Through a thorough examination, this work seeks to highlight the revolutionary power of quantum entanglement in protecting digital communication from the impending danger of classical computing power and future quantum assaults. A new age of private and secure communication may be on the horizon as a result of cryptographic systems that incorporate quantum entanglement.
