  "abstract": "Recently, there have been many attempts to implement quantum computation experimentally. For this purpose, quantum coherence should be maintained during gate operations. Therefore, the control of decoherence is a very important problem. In present study, we examine the decoherence of one-dimensional electron system, which coupled with acoustic phonon. The time-dependent Hatree-Fock approximation is applied for electron system, the Schroinger equation is applied for phonon.The metal-insulator transition found for coherence time. The results are the election interaction reduces the coherence time. We also exmined the Bang-Bang control, the results shows recovery of coherence.",
