    "abstract": "We combine elements of the 1998 quantum computing proposals by Privman,\nVagner and Kventsel, and by Kane, with the new idea of nuclear-spin qubit\ninteractions mediated indirectly via the bound outer electrons of impurity\natoms whose nuclear spins 1/2 are the qubits. These electrons, in turn,\ninteract via the two-dimensional electron gas in the quantum Hall effect\nregime. The resulting quantum computing scheme retains all the gate-control and\nmeasurement aspects of the proposal by Kane, but allows qubit spacing at\ndistances of order 100 nm, attainable with the present-day\nsemiconductor-heterostructure device technologies.",
