An entanglement protocol study within and without spy

Abstract

As quantum computing advances, traditional encryption methods face growing security threats. This study focuses on developing and testing a quantum key distribution protocol that leverages entanglement to secure data transmission. We simulate the protocol over optical fibers to analyze how distance, bit rate, and wavelength affect communication quality. Additionally, we assess the protocol’s ability to detect and resist eavesdropping by comparing scenarios with and without a spy. The goal is to enhance data security in quantum networks while ensuring efficient transmission, paving the way for more robust quantum communication systems.
