| 英文摘要 | In this paper we investigate the short-time decoherence from Ohmic and 1/f noise of single Josephson charge qubit (JCQ). At first, we use the short-time approximation to obtain the dynamics of the open JCQ. Then we calculate tile decoherence the measure of which is chosen as the maximum norm of the deviation density operator. It is shown that tile decoherence from 1/f noise plays the central role. The total decoherence from Ohmic and 1/f noise is serious at present experiential conditions according to tile DiVincenzo criterion. (c) 2005 Elsevier B.V. All rights reserved. |
