Using a scattering technique based on the Landauer-Buttiker formalism, we calculate the quantum conductance of multi-wall carbon nanotubes. We find that inter-wall interactions not only block some of the quantum conductance channels, but also redistribute the current non-uniformly over the individual tubes. Our results provide a natural explanation for the unexpected integer and non-integer conductance values observed for multi-wall nanotubes.
