    "abstract": "We present a tripartite three-level state that allows a secret sharing\nprotocol among the three parties, or a quantum key distribution protocol\nbetween any two parties. The state used in this scheme contains entanglement\neven after one system is traced out. We show how to utilize this residual\nentanglement for quantum key distribution purposes, and propose a realization\nof the scheme using entanglement of orbital angular momentum states of photons.",
