Constructs non-linear entanglement witnesses from any given linear witness that detect additional entangled states, including PPT entangled states, in d1 ⊗ d2 systems and are experimentally realizable via local observables.
In order to perform these quantum communication tasks, it is necessary to gener- ate entanglement between two or more subsystems
