    "abstract": "We propose a setup for a heralded, i.e. announced generation of a pure\nsingle-photon state given two imperfect sources whose outputs are represented\nby mixtures of the single-photon Fock state $\\ket{1}$ with the vacuum\n$\\ket{0}$. Our purification scheme uses beam splitters, photodetection and a\ntwo-photon-absorbing medium. The admixture of the vacuum is fully eliminated.\nWe discuss two potential realizations of the scheme.",
