    "abstract": "We propose a scheme to generate nonclassical states of a quantum system,\nwhich is composed of the one-dimensional trapped ion motion and a single cavity\nfield mode. We show that two-mode SU(2) Schr\\\"odinger-cat states, entangled\ncoherent states, two-mode squeezed vacuum states and their superposition can be\ngenerated. If the vibration mode and the cavity mode are used to represent\nseparately a qubit, a quantum phase gate can be implemented.",
