Abstract
Trapped ion systems are at the forefront of the development of various forms of quantum technology. Continuing to
improve and establish new devices and techniques for the control of trapped ions is a vital element of ongoing research. In
this thesis, a range of experiments which aim to expand the quantum toolkit of trapped ion systems are presented. These
results primarily focus on the control and detection of bound motional states of a single trapped 88Sr+ ion for the purposes
of quantum simulation and computation. We demonstrate how the interference between motional modes can reveal an
interesting new interpretation of the mechanism behind light-matter interaction and introduce two separate techniques
for the detection of motional states, based on the Autler-Townes effect and the use of composite pulses respectively.
Additionally, we introduce a novel method to perform micromotion compensation and build upon previous works studying
the effects of trapping electric fields on a single trapped Rydberg ion, observing the second-order quadrupolar response
of the ion with a highly precise sensitivity.
