    "abstract": "Secret sharing is a multiparty cryptographic task in which some secret\ninformation is splitted into several pieces which are distributed among the\nparticipants such that only an authorized set of participants can reconstruct\nthe original secret. Similar to quantum key distribution, in quantum secret\nsharing, the secrecy of the shared information relies not on computational\nassumptions, but on laws of quantum physics. Here, we present an experimental\ndemonstration of four-party quantum secret sharing via the resource of\nfour-photon entanglement.",
