    "abstract": "We develop a distillation protocol for multilevel qubits (qudits) using\ngeneralized beam splitters like in the proposal of Pan et al. for ordinary\nqubits. We find an acceleration with respect to the scheme of Bennet et al.\nwhen extended to qudits. It is also possible to distill entangled pairs of\nphotons carrying orbital angular momenta (OAM) states that conserves the total\nangular momenta as those produced in recent experiments.",
