Electric-field noise near surfaces is a common problem in diverse areas of physics and a
limiting factor for many precision measurements. There are multiple mechanisms by which …

Moving trapped-ion qubits in a microstructured array of radiofrequency traps offers a route
toward realizing scalable quantum processing nodes. Establishing such nodes, providing …

The availability of a universal quantum computer may have a fundamental impact on a vast
number of research fields and on society as a whole. An increasingly large scientific and …

Translationally cold, spatially localised molecular ions prepared by sympathetic cooling with
laser-cooled atomic ions in ion traps have recently found a wide range of applications in …

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 …

Ions confined using a Paul trap require a stable, high voltage and low noise radio frequency
(RF) potential. We present a guide for the design and construction of a helical coil resonator …

We report on the experimental investigation of an individual pseudomolecule using trapped
ions with adjustable magnetically induced J-type coupling between spin states. Resonances …

We report the design, fabrication and characterization of a microfabricated surface-electrode
ion trap that supports controlled transport through the two-dimensional intersection of linear …

Trapped-ion quantum-information processors offer many advantages for achieving high-
fidelity operations on a large number of qubits, but current experiments require bulky …

Scaling trapped-ion quantum computing will require robust trap** of at least hundreds of
ions over long periods, while increasing the complexity and functionality of the trap itself …
