    "abstract": "We report preparation in the ground state of collective modes of motion of\ntwo trapped 9Be+ ions. This is a crucial step towards realizing quantum logic\ngates which can entangle the ions\u0027 internal electronic states. We find that\nheating of the modes of relative ion motion is substantially suppressed\nrelative to that of the center-of-mass modes, suggesting the importance of\nthese modes in future experiments.",
