  "abstract": "The question whether all entangled states can be used as a nonclassical resource has remained open so far. Here we provide a conclusive answer to this problem for the case of systems shared by two parties. We show that any entangled state $\\sigma$ can enhance the teleportation power of some other state. This holds even if the state $\\sigma$ is bound entangled.",
