We provide generalizations of known two-qubit entanglement distillation protocols for arbitrary Hilbert space dimensions. The protocols, which are analogs of the hashing and breeding procedures, are adapted to bipartite quantum states that are diagonal in a basis of maximally entangled states. We show that the obtained rates are optimal, and thus equal to the distillable entanglement, for a (d-1)-parameter family of rank deficient states. Methods to improve the rates for other states are… Expand

The efficiency of the proposed scheme to distill entanglement from bipartite Fermionic systems in an arbitrary quasifree state is in general very good and in some cases even optimal and is applied to Fermions hopping on an infinite lattice. Expand
