    "abstract": "States with private correlations but little or no distillable entanglement\nwere recently reported. Here, we consider the secure distribution of such\nstates, i.e., the situation when an adversary gives two parties such states and\nthey have to verify privacy. We present a protocol which enables the parties to\nextract from such untrusted states an arbitrarily long and secure key, even\nthough the amount of distillable entanglement of the untrusted states can be\narbitrarily small.",
