Rare isotope Ca(0.187%) has been selectively loaded in a linear Paul trap by means of photo-ionization using ultraviolet LEDs in the second excitation. Sympathetic cooling of Ca and Ca has also been demonstrated. Trapped ions have been considered to be preferable physical system for realizing quantum information processor (QIP). Novel scheme to construct a large scale QIP based on trapped ions has recently been proposed. One of the key technologies for the proposal is sympathetic cooling where… CONTINUE READING
