An entanglement protocol study within and without spy

Abstract

As quantum computing advances, traditional encryption methods face growing security threats.This studyfocusesondevelopingandtestingaquantumkeydistributionprotocolthatleveragesentanglement 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 de- tect and resist eavesdropping by comparing scenarios with and without a spy.The goal is to enhance datasecurityinquantumnetworkswhileensuringefficienttransmission,pavingthewayformorerobust quantum communication systems.
