    "abstract": "We present a scheme utilizing position-dependent ac Stark shifts for doing\nquantum logic with trapped ions. By a proper choice of direction, position and\nsize, as well as power and frequency of a far-off-resonant Gaussian laser beam,\nspecific ac Stark shifts can be assigned to the individual ions, making them\ndistinguishable in frequency-space. In contrast to previous all-optical based\nquantum gates with trapped ions, the present scheme enables individual\naddressing of single ions and selective addressing of any pair of ions for\ntwo-ion quantum gates, without using tightly focused laser beams. Furthermore,\nthe decoherence rate due to off-resonant excitations can be made negligible as\ncompared with other sources of decoherence.",
