    "abstract": "We demonstrate experimentally how the process of Stimulated Raman Adiabatic\nPassage (STIRAP) can be utilized for efficient coherent internal state transfer\nin single trapped and laser-cooled $^{40}$Ca$^+$ ions. The transfer from the\nD$_{3/2}$ to the D$_{5/2}$ state, is detected by a fluorescence measurement\nrevealing the population not transfered to the D$_{5/2}$ state. A coherent\npopulation transfer efficiency at the level of 95 % in a setup allowing for the\ninternal state detection of individual ions in a string has been obtained.",
