    "abstract": "In this paper we investigate the short-time decoherence from Ohmic and 1/f\nnoise of single Josephson charge qubit (JCQ). At first, we use the short-time\napproximation to obtain the dynamics of the open JCQ. Then we calculate the\ndecoherence the measure of which is chosen as the maximum norm of the deviation\ndensity operator. It is shown that the decoherence from 1/f noise plays the\ncentral role. The total decoherence from Ohmic and 1/f noise is serious at\npresent experiential conditions according to the DiVincenzo criterion.",
