This chapter presents a review of quantum dots in two-dimensional electron gases. The spin qubits realized in these systems are strongly affected by the surrounding nuclear spins. An elegant demonstration is given that the nuclear spin bath is not as irreversible as one might think. Echo sequences can efficiently undo the dephasing of the qubitbrought about by the motion of nuclear spins.
Keywords: quantum dots, two-dimensional electron gas, spin qubit, dephasing, nuclear spin
