A scheme was proposed based on two levels of polarizing beam splitter (PBS) to purify relaying problem in the remote transmission process of quantum signaling. Three polarizing beam splitters were divided into two stages, the first stage including one splitter and the second stage including another two splitters. The three splitters make a new pair of entangled states after mixed-state quantum signaling going through two stages PBS. Using the new entangled states to replace the original mixed state would achieve the purpose of purification. The result shows that the entanglement purification method can purify quantum signaling effectively and it is applied well in many fields and easy to be operated. The scheme has certain technical reference for the future of transmission in quantum communication of signaling.
