All entangled states are useful for information processing
Ll. Masanes
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.
