A layered quantum communication path protocol cross multiple participants based on entanglement swapping

Quantum entanglement provides a contemporary secure channel for information communication, and the entanglement swapping builds newly entanglement on the previous isolate particles without direct interaction. In the paper, a novel-layered quantum communication path protocol cross multiple participants based on entanglement swapping is proposed, in which the communication path from sender to receiver across multiple intermediate nodes is constructed, and the constructed quantum channel is served for the information exchange. The present protocol can transmit message from sender to receiver via entanglement swapping. The presented protocol is useful for long-distance quantum information communication, significant to quantum network design and plan.
