Abstract

Combining the method of the multihop and the idea of the remote implementation of quantum operations, the multihop quantum operation teleportation is proposed in this paper, that is, the remote implementation of quantum operations in quantum multihop networks. Here the source and destination node do not directly share entangled states at first, which can be established through the entanglement swapping of the intermediate nodes. In addition, taking the phase-damping and the bit-flipping noise as typical noisy channels, we use the fidelity to quantify the effect of our protocol in these two types of noise environments. Furthermore, compared with the protocol employing classical sequential entanglement swapping, our protocol can reduce the communication delay using simultaneous measurements.
