    "abstract": "In this paper we investigate the short-time decoherence of single Josephson\ncharge qubit (JCQ). The measure of decoherence is chosen as the maximum norm of\nthe deviation density operator. It is shown that when the temperature low\nenough (for example T=30mK), within the elementary gate-operation time\ntau{g}~12.7ps, the decoherence is smaller than 0.0001 at present setup of JCQ.\nThe Josephson charge qubit is suitable to take the blocks for quantum\ncomputations according to the DiVincenzo low decoherence criterion.",
