Abstract :
We report the experimental realization of the four-partite bound-entangled state, i.e., Smolin state and demonstrate the ´superactivation´ of the bound entanglement. Bound entanglement is a class of multipartite entanglement that cannot be distilled into pure entanglement under local operations and classical communication (LOCC).
