    "abstract": "We report adiabatic passage experiments with a single trapped $^{40}$Ca$^+$\nion. By applying a frequency chirped laser pulse with a Gaussian amplitude\nenvelope we reach a transfer efficiency of 0.990(10) on an optical transition\nfrom the electronic ground state S$_{1/2}$ to the metastable state D$_{5/2}$.\nThis transfer method is shown to be insensitive to the accurate setting of\nlaser parameters, and therefore is suitable as a robust tool for ion based\nquantum computing.",
