Robust state preparation of a single trapped ion by adiabatic passage
References: [QIS19]
We report adiabatic passage experiments with a single trapped 40Ca+ ion. By applying a frequency chirped laser pulse with a Gaussian amplitude envelope we reach a transfer efficiency of 0.990(10) on an optical transition from the electronic ground state S1/2 to the metastable state D5/2. This transfer method is shown to be insensitive to the accurate setting of laser parameters, and therefore is suitable as a robust tool for ion based quantum computing.
