Trapped ions are among the most promising systems for practical quantum computing (QC).
The basic requirements for universal QC have all been demonstrated with ions, and …

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 …

The superconducting transmon qubit is a leading platform for quantum computing and
quantum science. Building large, useful quantum systems based on transmon qubits will …

The nitrogen-vacancy (NV) center in diamond exhibits spin-dependent fluorescence and
long spin coherence times under ambient conditions, enabling applications in quantum …

Here we review the field of atom chips in the context of Bose–Einstein Condensates (BEC)
as well as cold matter in general. Twenty years after the first realization of the BEC and 15 …

We probe the relaxation dynamics of the full three-level spin system of near-surface nitrogen-
vacancy (NV) centers in diamond to define a T 1 relaxation time that sets the T 2≤ 2 T 1 …

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 …

Abstract The Baryon Antibaryon Symmetry Experiment (BASE) aims at performing a
stringent test of the combined charge parity and time reversal (CPT) symmetry by comparing …

The energy resolution per bandwidth ER is a figure of merit that combines the field
resolution, bandwidth or duration of the measurement, and size of the sensed region …

We present measurements of trapped-ion motional-state heating rates in niobium and gold
surface-electrode ion traps over a range of trap-electrode temperatures from approximately …
