Abstract
An overview is given of how to generalize the breeding and hashing protocols to higher dimensions. The rates obtained are optimal only for special cases; however, they provide an improved lower bound to the distillable entanglement in general. Both protocols consist of two steps: first the quantum task is translated to a classical problem and then the latter is solved. The classical part of the protocol is already essentially optimal; however, some information and hence entanglement is lost during the translation process.
