▎ 摘 要
We investigate the entanglement teleportation via thermal Wannier edge states in a chiral graphene nanoribbon described by the effective Heisenberg model. The results show that in order to realize quantum teleportation the channel entanglement must be larger than a critical minimum value which depends on the entanglement of the initial input state. We also show that the teleportation fidelity is approximately close to the maximum at lower temperature. In particular, if Coulomb repulsion among electrons is smaller than 1.2 eV, the average fidelity will be larger than 2/3 even at room temperature.
