Nanotubes for future processors?

While some chip manufacturers are researching the 32nm fabrication process in the search for ever more powerful processors with ever less power consumption, an American research institute has determined that carbon nanotubes would outperform copper nanowires at the 45nm process node.  They have arrived at this conclusion by performing quantum mechanical computer modelling simulations rather than empirical laws.  The performance increase comes from bundles of nanotubes having far smaller electrical resistance than copper.  Anything that improves the performance of interconnects on future multi-core processors bodes well for the optimum speed/power consumption quest.
