Efficiently recycling these states to extract resources such as genuine multipartite entanglement and Einstein-Podolsky-Rosen pairs is essential for optimizing network performance. Our work demonstrates a tripartite entanglement distillation scheme using an eight-photon quantum platform, showcasing entanglement activation phenomena unique to multipartite systems. We successfully generate a three-photon genuinely entangled state from two bi-separable states through local operations and classical communication, illustrating multipartite entanglement activation. Furthermore, we extend our scheme to generate a three-photon state capable of extracting Einstein-Podolsky-Rosen pairs from two initial states lacking this capability, revealing a new entanglement activation phenomenon. Our findings offer not only practical applications for quantum networks but also a deeper theoretical understanding of multipartite entanglement structures.
