    "abstract": "It has been widely assumed that one-qubit gates in spin-based quantum\ncomputers suffer from severe technical difficulties. We show that one-qubit\ngates can in fact be generated using only modest and presently feasible\ntechnological requirements. Our solution uses only global magnetic fields and\ncontrollable Heisenberg exchange interactions, thus circumventing the need for\nsingle-spin addressing.",
