摘要：

The question of 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.
