Trapped-Ion Quantum Computing: Progress and Challenges
, 2019 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 quantum algorithms using few-ion-qubit systems have been implemented.

Quantum interference from remotely trapped ions [PDF]
, 2008 We observe quantum interference of photons emitted by two continuously laser-excited single ions, independently trapped in distinct vacuum vessels. High contrast two-photon interference is observed in two experiments with different ion species, calcium ...

Quantum repeaters based on two species trapped ions
New Journal of Physics, 2019 We examine the viability of quantum repeaters based on two-species trapped ion modules for long-distance quantum key distribution. Repeater nodes comprised of ion-trap modules of co-trapped ions of distinct species are considered.

Relativistic quantum mechanics with trapped ions [PDF]
, 2011 We consider the quantum simulation of relativistic quantum mechanics, as described by the Dirac equation and classical potentials, in trapped-ion systems. We concentrate on three problems of growing complexity.

Coherent control for qubit state readout
New Journal of Physics, 2020 Short pulses from mode-locked lasers can produce background-free atomic fluorescence by allowing temporal separation of the prompt incidental scatter from the subsequent atomic emission.

Control of Transverse Motion for Quantum Gates on Individually Addressed Atomic Qubits
PRX Quantum, 2022 Individual trapped atomic qubits represent one of the most promising technologies to scale quantum computers, owing to their low idle errors and the ability to implement a full set of reconfigurable gate operations via focused optical fields.

Quantum Algorithmic Readout in Multi-Ion Clocks [PDF]
, 2016 Optical clocks based on ensembles of trapped ions offer the perspective of record frequency uncertainty with good short-term stability. Most suitable atomic species lack closed transitions for fast detection such that the clock signal has to be read out ...
