Abstract We offer a comprehensive assessment of non-Markovianity (DNM) within an XX chain of interacting qubits linked to a reservoir. Our investigation incorporates di- verse quantum state distance (QSD) measures and considers various non-Markovian spectral densities, including the Lorentzian squared. This approach aims to pro- vide a robust evaluation of DNM. By constructing the density matrix of the open chain without relying on a master equation, we analyze the dynamics of QSD mea- sures between Markovian and non-Markovian damping scenarios. Recognizing that conventional QSD measures often presume trace-preserving density matrices, we adapt them to accommodate damped traces in open systems. Our findings not only demonstrate consistent outcomes across different QSD measures but also reveal in- tricate interactions between qubit-qubit coupling, non-Markovian damping, and en- tanglement dynamics, particularly notable when exploring the implications of the Lorentzian squared spectral density.
