- Abstract: In this article, we investigate the entanglement evolution of three-qubit states in the presence of a spin chain environment. Utilizing negativity as a metric for entanglement assessment, we focus on the GHZ, W, and W_zeta quantum states as the initial system states. We explore and analyze the entanglement dynamics of these states based on various parameters.
