    "abstract": "We describe how two vibrational degrees of freedom of a single trapped ion\ncan be coupled through the action of suitably-chosen laser excitation. We\nconcentrate on a two-dimensional ion trap with dissimilar vibrational\nfrequencies in the x- and y-directions of motion, and derive from first\nprinciples a variety of quantized two-mode couplings, concentrating on a linear\ncoupling which takes excitations from one mode to another. We demonstrate how\nthis can result in a state rotation, in which it is possible to transfer the\nmotional state of the ion from say the x-direction to the y-direction without\nprior knowledge of that motional state.",
