    "abstract": "In this paper we investigate decoherence times of a double quantum dot (DQD)\ncharge qubit due to it coupling with acoustic phonon baths. We individually\nconsider the acoustic piezoelectric as well as deformation coupling phonon\nbaths in the qubit environment. The decoherence times are calculated with two\nkinds of methods. One of them is based on the qusiadiabatic propagator path\nintegral (QUAPI) and the other is based on Bloch equations, and two kinds of\nresults are compared. It is shown that the theoretical decoherence times of the\nDQD charge qubit are shorter than the experimental reported results. It implies\nthat the phonon couplings to the qubit play a subordinate role, resulting in\nthe decoherence of the qubit.",
