Abstract

We demonstrate confinement of individual atomic ions in an RF Paul trap with novel geometry where the electrodes are located in a single plane and the ions confined above this plane. This device is realized with a simple fabrication procedure and has important implications for quantum state manipulation and quantum information processing on large numbers of ions. We confine laser-cooled ²⁴Mg⁺ ions approximately 40 υm above planar gold electrodes. We measure the ions' motional frequencies and compare them to simulations. From measurements of the escape time of ions from the trap, we also determine a heating rate of approximately 4 motional quanta per ms for a trap frequency of 5.3 MHz.
