Web16 jun. 2004 · The Nist team in Boulder, Colorado, used ions of the element beryllium. Despite this and some differences in the experimental methods used by the two groups, both teams reached similar values of fidelity - around 0.75. Fidelity is a measure of how well the quantum state of the second ion after teleportation resembles the original quantum … Web7 apr. 2024 · In one experiment we make use of a segmented three-dimensional Paul trap (Fig. 1) in which we confine magnesium and beryllium ions in linear arrays. The trap features two trapping zones to split and recombine ion crystals and an X-shaped junction, which can be used to reorder ions in a linear array [1].
