摘要: We report on ground-state laser cooling of single {sup 111}Cd{sup +} ions confined in radio-frequency (Paul) traps. Heating rates trapped ion motion are measured for two different trapping geometries and electrode materials, where no effort was made to shield the electrodes from atomic Cd source. The low heating suggest that may be well suited experiments involving quantum control motion, including applications information science.
