By using an order N quantum transport methodology, and treating on the same footing static and dynamical disorders, we report on the theoretical exploration of quantum interferences tuned by electron-phonon mediated decoherence mechanisms in disordered carbon nanotubes (with length up to 10 microm). This allows the extraction of inelastic scattering times together with temperature-dependent coherence lengths, which favorably compare with available experimental data at a quantitative level, and clarify the role of localization phenomena up to room temperature.
