For trapped atomic ions, the quantized motional and internal degrees of freedom can be coherently manipulated with laser light. Similar control is difficult to achieve with radio frequency or microwave radiation because the essential coupling between internal degrees of freedom and motion requires significant field changes over the extent of the atoms' motion. The field gradients are negligible at these frequencies for freely pro","authors_text":"C. Ospelkaus, D. J. Wineland, D. Leibfried, J. M. Amini, K. R. Brown, U. Warring, Y.
