In our proposed CQT scheme, Trent provides an entanglement channel to Alice and Bob using the interactions between two photons and the single-sided QD-cavity system (QD1). Then, Alice can teleport the unknown state of an electron in the double-sided QD-cavity system (QD2) to Bob through the entanglement channel. Subsequently, for reconstruction of a teleported unknown state in the single-sided QD-cavity system (QD3) on Bob’s side, the classical information of Trent and Alice are required. Here, the resulting measurement of the electron spin of QD1 (Trent) guarantees authentication of the entanglement channel for secure communication.
