Abstract
With the recent surge for an experimentally viable quantum computer, trapped ions have come to the forefront as one of the most practical systems from which to construct a quantum computing architecture. This work has continued to explore the feasibility of using trapped ions as quantum bits, addressing the issue of quantum decoherence due to non-resonant excitation by studying the spectroscopy of a trapped ion through a standing wave.
The standing wave studied in this thesis was formed on the face of a surface-electrode ion trap held at cryogenic temperatures. Although the trap was not built with a reflective surface in mind, a lower bound on the fringe visibility was measured to be 0.717. By moving the ion through the nodes and anti-nodes of the wave, the carrier and sidebands of the S_1/2 to D_5/2 transition, commonly used for information storage, were selectively stimulated and suppressed.
