Optical atomic clocks are our most precise tools to measure time and frequency,–. Precision
frequency comparisons between clocks in separate locations enable one to probe the space …

We integrate a long-lived memory qubit into a mixed-species trapped-ion quantum network
node. Ion-photon entanglement first generated with a network qubit in Sr+ 88 is transferred …

One of the most formidable challenges of scaling up quantum computers is that of control-
signal delivery. Today's small-scale quantum computers typically connect each qubit to one …

Experimental setups that study laser-cooled ions immersed in baths of ultracold atoms
merge the two exciting and well-established fields of quantum gases and trapped ions …

Volume 54 of the Advances in Atomic, Molecular, and Optical Physics Series contains ten
contributions, covering a diversity of subject areas in atomic, molecular and optical physics …

We minimize the stray electric field in a linear Paul trap quickly and accurately, by applying
interferometry pulse sequences to a trapped ion optical qubit. The interferometry sequences …

Ions displaced from the potential minimum in an RF Paul trap exhibit excess micromotion. A
host of well-established techniques are routinely used to sense (and null) this excessive …

We investigate melting and undercooling in nanoscale (radius∼ 100 nm) gold particles that
are levitated in a quadrupole ion (Paul) trap in a high vacuum environment. The particle is …

Quantum information promises to revolutionize our world, from the way in which we
communicate to the way in which we compute, deriving its power directly from the laws that …

Trapped ions in a Paul trap can experience micromotion on top of the wanted secular
motion. Micromotion can for example cause Doppler shifts in spectroscopy measurements …
