The Husimi phase-space distribution is an efficient tool for studying quantum coherent states
as it provides information on quantum-state features. The paper investigates the non …

We present a study of the coherence properties of a variety of motional states of a single ion
confined in a Penning ion trap. We demonstrate that the motion of the ion has a coherence …

Cooling down a trapped ion into its motional ground state is a central step for trapped-ion-
based quantum information processing. State-of-the-art cooling schemes often work under a …
