“…By restricting ourselves to the case of heavier alkali-earth (i.e. species with D metastable states), these techniques have been recently applied to obtain precision measurements of spectroscopical quantities on laser-cooled 40 Ca + ions [9][10][11][12], 138 Ba + ions [13][14][15], and 88 Sr + ions [16][17][18][19]. In this paper we present the precision measurement of the branching fractions for the decay of the 5p 2 P 1/2 state of 88 Sr + .…”

“…1 shows the relevant atomic levels of the isotope 40 Ca + . The actual clock transition considered here is the electric quadrupole transition from the 4s 2 S 1/2 to the 3d 2 D 5/2 level, which has a natural lifetime of 1.17 s [12]. A non-zero magnetic field lifts the Zeeman degeneracy and splits the transition into ten lines.…”

Solution to the satisfiability problem using a complete Grover search with trapped ions

“…In contrast, the lifetime of the metastable level D 5/2 of 40 Ca + is much long, i.e., for about 1.16 sec [43]. So our operational time should be restricted within tens of millisec.…”
