| Abstract: | We obtain the energy, of the ground state and the first excited state of the confined system of electron-phonon interacting in cylindrical quantum dot by solving precisely the energy eigen-equation and a quantum bit （qubit） is formed by both the ground state and the first excited state of the electron. The numerical results for GaAs quantum dot indicate that the energy of the system decrease with increasing radius or cylindrical height, and the period of oscillation of quantum bit increase with increasing radius or cylindrical height. |
