The relevance of random choice in tests of Bell inequalities with atomic qubits [PDF]
, 2009 It is pointed out that a loophole exists in experimental tests of Bell inequality using atomic qubits, due to possible errors in the rotation angles of the atomic states.

Wavelength-Scale Imaging of Trapped Ions using a Phase Fresnel lens [PDF]
, 2011 A microfabricated phase Fresnel lens was used to image ytterbium ions trapped in a radio frequency Paul trap. The ions were laser cooled close to the Doppler limit on the 369.5 nm transition, reducing the ion motion so that each ion formed a near point ...

A short response-time atomic source for trapped ion experiments [PDF]
, 2018 Ion traps are often loaded from atomic beams produced by resistively heated ovens. We demonstrate an atomic oven which has been designed for fast control of the atomic flux density and reproducible construction.

Hexagonal plaquette spin–spin interactions and quantum magnetism in a two-dimensional ion crystal
New Journal of Physics, 2015 We propose a trapped ion scheme en route to realize spin Hamiltonians on a Kagome lattice which, at low energies, are described by emergent ${{\mathbb{Z}}}_{2}$ gauge fields, and support a topological quantum spin liquid ground state.

Injection Locking of a Trapped-Ion Phonon Laser [PDF]
, 2010 We report on injection locking of optically excited mechanical oscillations of a single, trapped ion. The injection locking dynamics are studied by analyzing the oscillator spectrum with a spatially selective Fourier transform technique and the ...

Structural and energetic properties of molecular Coulomb crystals in a surface-electrode ion trap
New Journal of Physics, 2015 Cold molecular ions are of great interest for applications in cold collision studies, chemistry, precision spectroscopy and quantum technologies. In this context, sympathetic cooling of molecular ions by the interaction with laser-cooled atomic ions is a

A robust scheme for the implementation of the quantum Rabi model in trapped ions
New Journal of Physics, 2016 We show that the technique known as concatenated continuous dynamical decoupling (CCD) can be applied to a trapped-ion setup for a robust implementation of the quantum Rabi model in a variety of parameter regimes.

Quantum-enhanced deliberation of learning agents using trapped ions
New Journal of Physics, 2015 A scheme that successfully employs quantum mechanics in the design of autonomous learning agents has recently been reported in the context of the projective simulation (PS) model for artificial intelligence.

Atoms, 2016 The study of highly charged ions (HCI) was pursued first at Uppsala (Sweden), by Edlén and Tyrén in the 1930s. Their work led to the recognition that the solar corona is populated by such ions, an insight which forced massive paradigm changes in solar ...

Generation of spin-motion entanglement in a trapped ion using long-wavelength radiation [PDF]
, 2014 Applying a magnetic-field gradient to a trapped ion allows long-wavelength radiation to produce a mechanical force on the ion's motion when internal transitions are driven.
