This study investigates how the entanglement dynamics of separable and Werner states differ in a finite Markovian N-qubit environment under two environmental conditions: homogeneous and white noise. We demonstrate that in a homogeneous environment, the entanglement dynamics of the separable state is influenced by interactions between subsystems $\omega_{S_1 S_2}$ and the environment $\Gamma$, while for Werner states it depends solely on $\Gamma$. Both states exhibit unique properties that enable us to distinguish the initial state through their entanglement dynamics and maximum concurrence. In contrast, in a white noise environment, the decay time of entanglement is determined only by the size of the environment and the randomness of interaction strengths, underscoring the significant role of environmental factors in quantum dynamics. |
