Scalable quantum logic spectroscopy
Kaifeng Cui, Jose Valencia, Kevin T. Boyce +2
In quantum logic spectroscopy (QLS), one species of trapped ion is used as a sensor to detect the state of an otherwise inaccessible ion species. This extends precision measurement…
Rotational spectroscopy of a single molecular ion at sub part-per-trillion resolution
Alejandra L. Collopy, Julian Schmidt, Dietrich Leibfried +2
We use quantum-logic spectroscopy (QLS) and interrogate rotational transitions of a single CaH+ ion with a highly coherent frequency comb, achieving a fractional statistical uncert…
Prospects of a thousand-ion Sn Coulomb-crystal clock with sub- inaccuracy
David R. Leibrandt, Sergey G. Porsev, Charles Cheung +1
We propose a many-ion optical atomic clock based on three-dimensional Coulomb crystals of order one thousand Sn ions confined in a linear RF Paul trap. Sn has a uniqu…
