The entanglement of two atoms (ions) doped into a carbon nanotube has been
investigated theoretically. Based on the photon Green function formalism for
quantizing electromagnetic field in the presence of carbon nanotubes,
small-diameter metallic nanotubes are shown to result in a high degree of the
two-qubit atomic entanglement for long times due to the strong atom-field
coupling.Comment: 4 pages, 2 figure
