document: Quantum computing with spin qubits in semiconductor structures We survey recent work on designing and evaluating quantum computing implementations based on nuclear or bound-electron spins in semiconductor heterostructures at low temperatures and in high magnetic fields . General overview is followed by a summary of results of our theoretical calculations of decoherence time scales and spin-spin interactions . The latter were carried out for systems for which the two-dimensional electron gas provides the dominant carrier for spin dynamics via exchange of spin-excitons in the integer quantum Hall regime
