摘要：

We investigate the entanglement of quasi-one-dimensional atomic polariton states formed by atoms (ions) located close to or encapsulated inside carbon nanotubes and strongly coupled to the nanotube virtual photonic modes. Small-diameter metallic nanotubes are shown to result in sizable amounts of two-qubit atomic entanglement, which persists with no damping for very long times.
