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 …

Integration of fiber optics may play a critical role in the development of quantum information
processors based on trapped ions and atoms by enabling scalable collection and delivery of …

We describe the advantages of two-dimensional (2D), addressable arrays of spherical Paul
traps. They would provide the ability to address and tailor the interaction strengths of trapped …

We report one-dimensional pinning of a single ion by an optical lattice. A standing-wave
cavity produces the lattice potential along the rf-field-free axis of a linear Paul trap. The ion's …

Laser cooling typically requires one or more repump lasers to clear dark states, which
complicates experimental setups, especially for systems with multiple repumping …

One path to realizing systems of trapped atomic ions suitable for large-scale quantum
computing and simulation is to create a two-dimensional (2D) array of ion traps. Interactions …

An atomic ion is trapped at the tip of a single-mode optical fiber in a cryogenic (8 K) surface-
electrode ion trap. The fiber serves as an integrated source of laser light, which drives the …

We model electric field noise from fluctuating patch potentials on conducting surfaces by
taking into account the finite geometry of the ion trap electrodes to gain insight into the origin …

We report on the alteration of photon-emission properties of a single trapped ion coupled to
a high-finesse optical fiber cavity. We show that the vacuum field of the cavity can …

Key requirements for efficient large-scale quantum computing (QC) include reliable transport
of information throughout the processor and the ability to perform gates between arbitrarily …
