| Abstract | We discuss the effect of a charged impurity on the qubit encoded in the two low-energy states of an electrostatically defined triple quantum dot with one-electron spin in each dot. The two qubit levels are identified with the two opposite directions of the motion of a minority spin. The effect of the charged impurity on the coded qubit is mapped onto the problem of an effective spin in a random magnetic field. The effective magnetic field is related to exchange rather than Coulomb interaction which ensures stability of the coded qubit with respect to charge fluctuations. |
