摘要：
We investigate the effects of noisy quantum channels on the entanglement of cluster states and one way quantum computational gates. We take a basic model, the rotational gate about x axis based on the cluster state, in order to get the most essential effects of the paradigmatic noisy quantum channels. The entanglement of cluster states in the noisy channels and the fidelity between the rotated state without noisy channel and that with noisy channel are calculated.
