Qubit Entanglement from a Bipartite Atomic System in a Carbon Nanotube

摘要

We study a scheme for the entanglement of two two-level atoms based on the previously developed photon Green function formalism for quantizing an electromagnetic field in the presence of a carbon nanotube. We show that the (resonator-like) cylindrical nanotube environment can result in a significant degree of quantum-bit entanglement of the bipartite atomic subsystem.
