    "abstract": "In this paper we investigate decoherence time of superconducting Josephson\ncharge qubit (JCQ). Two kinds of methods, iterative tensor multiplication (ITM)\nmethod derived from the qusiadiabatic propagator path integral (QUAPI) and\nBloch equations method are used. Using the non-Markovian ITM method we correct\nthe decoherence time predicted by Bloch equations method. By comparing the\nexact theoretical result with the experimental data we suggest that the Ohmic\nnoise plays the central role to the decoherence of the JCQ.",
