Abstract
Multi-hop remote quantum teleportation has significant value in wireless quantum network and long distance quantum information transmission. Due to the long distance transmission of quantum information will be affected by the interference of noise, this makes quantum states nonlocal decoherence, so multi-hop teleportation through intermediate nodes has significant theory and application value to study on this subject. In this paper, we propose a multi-hop teleportation scheme based on wireless mesh network, and the scheme of transmitting arbitrary four-qubit states is optimized. With the aid of auxiliary particles, information can be transmitted with fewer quantum channels. Compared with hop-by-hop transmission, this optimized scheme can remarkably reduce the transmission delay and improve the transmission efficiency. The introduction of wireless mesh network also makes the theory of multi-hop teleportation more practical.
