Optical communication channels have redefined the scope and applications of classical
computing; similarly, photonic transfer of quantum information promises to open new …

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 …

We implement all single-qubit operations with fidelities significantly above the minimum
threshold required for fault-tolerant quantum computing, using a trapped-ion qubit stored in …

Quantum emitters such as the diamond nitrogen-vacancy (NV) center are the basis for a
wide range of quantum technologies. However, refraction and reflections at material …

Qubits used in quantum computing suffer from errors, either from the qubit interacting with
the environment, or from imperfect quantum logic gates. Effective quantum error correcting …

We present and characterize fiber mirrors and a miniaturized ion-trap design developed to
integrate a fiber-based Fabry-Perot cavity (FFPC) with a linear Paul trap for use in cavity …

Recent advances in quantum information processing with trapped ions have demonstrated
the need for new ion trap architectures capable of holding and manipulating chains of many …

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 …

We measure ion heating following transport throughout a Y-junction surface-electrode ion
trap. By carefully selecting the trap voltage update rate during adiabatic transport along a …

State-of-the-art microfabricated ion traps for quantum information research are approaching
nearly one hundred control electrodes. We report here on the development and testing of a …
