Abstract
We demonstrate co-trapping and sideband cooling of a H - Be ion pair in a cryogenic Paul trap. We study the chemical lifetime of H and its dependence on the apparatus temperature, achieving lifetimes of up to h at 10 K. We demonstrate cooling of two of the modes of translational motion to an average phonon number of 0.07(1) and 0.05(1), corresponding to a temperature of 22(1) K and 55(3) K respectively. Our results provide a basis for quantum logic spectroscopy experiments of H, as well as other light ions such as HD, H, and He.
