The purpose of this paper is to discuss the controlled teleportation of unknown single-particle states by using high-dimensional entangled states as quantum channels. A controlled teleportation protocol for two-dimensional arbitrary single-particle state is proposed by using three-dimensional entangled state as channel. A teleportation protocol of a [t]-dimensional arbitrary single-particle state is presented by using an arbitrary [d]-dimensional entangled state [(t<d)] as the quantum channel, which is a direct generalization of the previous protocol. The main strategy of these protocols is teleportation of an unknown single-particle state, which consists of asymmetric basic measurement, generalized projective measurement and corresponding local transformation.

Key words: quantum communication, controlled teleportation, high-dimensional entangled state, asymmetric basis measurement, generalized projective measurement
