One approach to quantum information and quantum computation relies on physical systems with continuous degrees of freedom, or 'continuous variables'. In this context, one usually employs the quadratures of the light field as the physical implementation of quantum information. In this project, we investigate the preparation and manipulation of non-classical states using the vibrational modes (i.e. the position and momentum degrees of freedom) of a trapped Yb ion, which are formally identical to the quadratures of the electromagnetic field. The ionic internal degrees of freedom are utilised both for the readout of the motional state and for mediating interaction between different vibrational modes. We aim at preparing useful quantum states to demonstrate coherent control over a continuous variables system.
