A scheme of manipulating duplex hybrid entanglement based on linear optics is presented. In the scheme, a variable beam splitter (VBS) is used to generate duplex hybrid entangled states, the hybrid entanglement manipulation is realized by adjusting the splitting ratio of VBS, and the influence of the cat state size on fidelity is analyzed. This scheme provides theoretical reference for the generation of multiplex hybrid entanglement and its application in hybrid quantum communications.
