    "abstract": "We provide generalizations of known two-qubit entanglement distillation\nprotocols for arbitrary Hilbert space dimensions. The protocols, which are\nanalogues of the hashing and breeding procedures, are adapted to bipartite\nquantum states which are diagonal in a basis of maximally entangled states. We\nshow that the obtained rates are optimal, and thus equal to the distillable\nentanglement, for a (d-1) parameter family of rank deficient states. Methods to\nimprove the rates for other states are discussed. In particular, for isotropic\nstates it is shown that the rate can be improved such that it approaches the\nrelative entropy of entanglement in the limit of large dimensions.",
