Abstract: A novel scheme for multi-quantum-state sharing is proposed based on the relay system with teleportation in the non-maximally-entangled channel in order to improve the efficiency of secure distribution of quantum states for communications. Multi quantum states are encoded as quantum packets and teleported from the source to the destination with assistance of the relay. It demonstrates that secure multi quantum states sharing can be achieved and meanwhile the range of quantum communication can be increased and approximately doubled. It provides a valuable application prospect in long distance reliable communications and a wide application to quantum networks.

Keywords: quantum communications; quantum state sharing protocol; non-maximally entanglement channels; quantum relay systems; teleportation; quantum packets; quantum networks.
