Qubit Entanglement Using Doped Carbon Nanotubes

We study theoretically, two doped Carbon nanotubes connected via a chemically active bond as the basic elementary gate for a recent proposal for qubit teleportation in the solid--state. We show that such a system provides the necessary entanglement between electron and electron--hole that is necessary for qubit teleportation. We simulate the transit of a defined qubit using time--dependent density functional theory within our structure. Finally, we critically discuss the implications of our design.
