We demonstrate unprecedentedly long lifetimes for electron spin superposition states of a single trapped \(^{40}\)Ca\(^+\) ion. For a Ramsey measurement, we achieve a \(1{/}\sqrt{e}\) coherence time of 300(50) ms, while a spin-echo experiment yields

We experimentally demonstrate fast separation of a two-ion crystal in a microstructured segmented Paul trap. By the use of spectroscopic calibration routines for the electrostatic trap potentials, we achieve the required precise control of the ion tr
