    "abstract": "We present new algorithms for mixed-state multi-copy entanglement\ndistillation for pairs of qubits. Our algorithms perform significantly better\nthan the best known algorithms. Better algorithms can be derived that are tuned\nfor specific initial states. The new algorithms are based on a characterization\nof the group of all locally realizable permutations of the 4^n possible tensor\nproducts of n Bell states.",
