"In this talk I will report on recent progress made at NIST Boulder in the manipulation of ions using microfabricated surface 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."
