Generation of time-bin-encoded photons in an ion-cavity system
New Journal of Physics, 2022 We investigate two single-photon generation schemes and compare their suitability for use in time-bin entanglement encoding. A trapped ion coupled to an optical cavity produces single photons through a cavity-assisted Raman transition.

Determining reaction pathways at low temperatures by isotopic substitution: the case of BeD + + H2O
New Journal of Physics, 2021 Trapped Be ^+ ions are a leading platform for quantum information science (Gaebler et al 2016 Phys. Rev. Lett. 117 060505 117 117 060505 ), but reactions with background gas species, such as H _2 and H _2 O, result in qubit loss.

Generalized Dicke nonequilibrium dynamics in trapped ions [PDF]
, 2014 We explore trapped ions as a setting to investigate nonequilibrium phases in a generalized Dicke model of dissipative spins coupled to phonon modes. We find a rich dynamical phase diagram including superradiantlike regimes, dynamical phase coexistence ...

Modeling ion effects for the Argonne Advanced Photon Source upgrade
Physical Review Accelerators and Beams, 2019 Ions are produced in an accelerator when the beam ionizes residual gas inside the vacuum chamber. If the beam is negatively charged, ions can become trapped in the beams potential, and their density will increase over time.

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.

A quantum information processor with trapped ions
New Journal of Physics, 2013 Quantum computers hold the promise to solve certain problems exponentially faster than their classical counterparts. Trapped atomic ions are among the physical systems in which building such a computing device seems viable.

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.

Phosphoinositides and inositol phosphates as molecular glues
FEBS Letters, EarlyView.Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.
