Summary: We present a scheme for teleporting multi-qudit quantum state, from the sender Alice to the receiver Charlie via many controllers Bobs, whose control parameters are obtained using entanglement swapping of maximally \(d\)-dimensional EPR pair. In our scheme, Yang’s qutrit controlled teleportation protocol [Commun. Theor. Phys. 49, 338 (2008)] based on Bell-state entanglement swapping is generalized to the qudit case. The scheme of multi-qudit owns the advantage of having higher code capacity and better security than that of multi-qutrit.
