摘要

Based on quantum multi-hop networks, a general scheme is designed for remote implementation of quantum operations. Firstly, different types of GHZ states are shared in advance along the quantum path. Subsequently, by employing bidirectional quantum teleportation, finite state machines are constructed to determine the recovery operations at both the source and destination nodes. Furthermore, in comparison with existing similar schemes, the proposed approach achieves a reduction in classical communication cost by approximately 25% as the number of hops increases.
