    "abstract": "A circular quantum secret sharing protocol is proposed, which is useful and\nefficient when one of the parties of secret sharing is remote to the others who\nare in adjacent, especially the parties are more than three. We describe the\nprocess of this protocol and discuss its security when the quantum information\ncarrying is polarized single photons running circularly. It will be shown that\nentanglement is not necessary for quantum secret sharing. Moreover, the\ntheoretic efficiency is improved to approach 100% as almost all the instances\ncan be used for generating the private key, and each photon can carry one bit\nof information without quantum storage. It is straightforwardly to utilize this\ntopological structure to complete quantum secret sharing with multi-level\ntwo-particle entanglement in high capacity securely.",
