"Recent experiments with ions in microfabricated surface-electrode traps"
In this talk I will report on recent progress made at NIST Boulder in
the manipulation of ions using microfabricated surface-electrode traps.
A first experiment performs a laser-less two qubit logic gate, taking
advantage of the high magnetic field gradients that can be generated on
ion chips. A second experiment, operated at cryogenic temperature, shows
the exchange of a single quantum of vibration between two ions trapped
40 micrometers apart. Lastly, I will describe an experiment where the
anomalous heating rate of a trapped ion is reduced by a factor of 100
after in-situ cleaning of the surface of the trap.
