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.

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.

Trapped ion quantum information processing using multiple qubit encodings [PDF]
Trapped atomic ions are one of the most promising platforms for developing a quantum computer. On a small scale, they have shown the longest qubit coherence times [1] and the highest single- and two-qubit gate fidelities [2–5].

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 ...

Scalable imaging of trapped ions [PDF]
, 2011 Wavelength scale imaging of trapped Ytterbium ions was demonstrated using a microfabricated phase Fresnel lens. Near diffraction-limited spot sizes of below 440 nm (FWHM) were achieved, an important precursor to efficient single-mode coupling.Full ...

Laser-Cooled Ion Beams and Strongly Coupled Plasmas for Precision Experiments [PDF]
, 2008 The first part of this thesis summarizes the results of laser-cooling of relativistic C3+ ion beams at the ESR/GSI. It is shown that laser cooling at high beam energies is feasible and that momentum spreads much smaller than those observed for electron ...

Trapped modes in a waveguide with a thick obstacle [PDF]
, 2004 The problem of finding necessary and sufficient condi-tions for the existence of trapped modes in waveguides has been known since 1943. [10]. The problem is the following: consider an infinite strip M in xs211D2(or an infinite cylinder with the smooth ...

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.

Reconstructing enzyme evolution by protein engineering
FEBS Letters, EarlyView.Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
