Quantum computers hold the promise of solving certain computational tasks much more
efficiently than classical computers. We review recent experimental advances towards a …

Atomic ions trapped in electromagnetic potentials have long been used for fundamental
studies in quantum physics. Over the past two decades, trapped ions have been …

Direct experimental access to some of the most intriguing quantum phenomena is not
granted due to the lack of precise control of the relevant parameters in their naturally …

By isolating from the environment and precisely controlling mesoscopic objects, levitation in
vacuum has evolved into a versatile technique that has already benefited diverse scientific …

Individual laser-cooled Mg+ 24 ions are confined in a linear Paul trap with a novel geometry
where gold electrodes are located in a single plane and the ions are trapped 40 μ m above …

Resource efficient schemes for the quantum simulation of lattice gauge theories can benefit
from hybrid encodings of gauge and matter fields that use the native degrees of freedom …

In this paper, we report the design, fabrication and preliminary testing of a 150 zone ion trap
array built in a 'surface-electrode'geometry microfabricated on a single substrate. We …

Small, controllable, highly accessible quantum systems can serve as probes at the single-
quantum level to study a number of physical effects, for example in quantum optics or for …

Multipole radiofrequency ion traps are a highly versatile tool to study molecular ions and
their interactions in a well-controllable environment. In particular the cryogenic 22-pole ion …

The design of surface-electrode ion traps is studied analytically. The classical motion of a
single ion in such a trap is described by coupled Mathieu equations. An analytic boundary …
