| Abstract: | The properties of single-qubit logic gates was studied under the effects of non-Markov environments.It was found out that the non-Markovianity of quantum process was beneficial for the suppression of mistakes induced by environments,so that improved the quality of logic operation; when the operation time of the noisy gate was slightly smaller than the one of the corresponding ideal gate,the accuracy of the logic gate was the best. |

| Keywords: | single-qubit gate non-Markovianity average fidelity optimal operation time |
