    "abstract": "In the viewpoint of quasi normal modes, we describe a novel decoherence\nmechanism of charge qubit of Josephson Junctions (JJ) in a lossy micro-cavity,\nwhich can appear in the realistic experiment for quantum computation based on\nJJ qubit. We show that the nonlinear coupling of a charge qubit to quantum\ncavity field can result in an additional dissipation of resonant mode due to\nits effective interaction between those non-resonant modes and a resonant mode,\nwhich is induced by the charge qubit itself. We calculate the characterized\ntime of the novel decoherence by making use of the system plus bath method.",
