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 …

Trapped-ion quantum information processors store information in atomic ions maintained in
position in free space by electric fields. Quantum logic is enacted through manipulation of …

Cold ions trapped in the vicinity of conductive surfaces experience heating of their oscillatory
motion. Typically, the rate of this heating is orders of magnitude larger than expected from …

Laser cleaning of the electrodes in a planar micro-fabricated ion trap has been attempted
using ns pulses from a tripled Nd: YAG laser at 355 nm. The effect of the laser pulses at …

Electric-field noise due to surfaces disturbs the motion of nearby trapped ions, compromising
the fidelity of gate operations that are the basis for quantum computing algorithms. We …

Our experience of the world around us is governed almost entirely by light–matter
interactions. At the most fundamental level, such interactions are described by quantum …

Metal whiskers often grow across leads of electric equipment and electronic package
causing current leakage or short circuits and raising significant reliability issues. The nature …

Decoherence and relaxation of solid-state defect qutrits near a crystal surface, where they
are commonly used as quantum sensors, originate from charge and magnetic field noise. A …

We probe electric-field noise near the metal surface of an ion-trap chip in the temperature
range from 295 to 530 K. We observe a nontrivial temperature dependence with the noise …

The electric fields near the heterogeneous metal-dielectric surface of an atom chip were
measured using cold atoms. The atomic sensitivity to electric fields was enhanced by …
