Binding entanglement channels

Abstract

We define the binding entanglement channel as the quantum channel through which quantum information cannot be reliably transmitted, but which can be used to share bound entanglement. We provide a characterization of such class of channels. We also show that any bound entangled state can be used to construction of the map corresponding the binding entanglement channel.
