    "abstract": "We put forward a method for optimized distillation of partly entangled pairs\nof qubits into a smaller number of more entangled pairs by recurrent local\nunitary operations and projections. Optimized distillation is achieved by\nminimization of a cost function with up to 30 real parameters, which is chosen\nto be sensitive to the fidelity and the projection probability at each step. We\nshow that in many cases this approach can significantly improve the\ndistillation efficiency in comparison to the present methods.",
