    • In the present study, dissipation means the relaxation of the population of bonding-antibonding states. On large time scales, the qubit state becomes mixed with equal populations of bonding and antibonding states; this relaxation is not an energy relaxation.

    • note
    • In the present study, we assume the interaction between the coupled-dot system and charge state to be dipole-monopole coupling. When the electron reservoir screens the charge state effectively, the charge state and reservoir act on the system as a dipole. The interaction type is dipole-dipole, and the interaction strength decreases more rapidly as the distance between the charge state and system increases. A longer dephasing time is thus expected compared with that of a dipole-monopole interaction.
