A method of generating the single-photon entangled states of a single photon state and a vacuum state through utilizing optical beam-splitter and single-photon source is described. A setup for realizing entanglement translation of the single-photon entangled state is designed. A proposal is presented for teleporting an unknown single-photon entangled state. In this proposed,the two single-photon entangled states is utilized as the quantum channel. The process of the entanglement translation and quantum teleportation are achieved by using the 50/50 symmetric beam splitters and the photon detectors with the help of classical information.
