    A new scheme is proposed to implement quantum logic gates such as single qubit rotation gate, two qubit controlled-phase gate and controlled-NOT gate, using the method based on a quantum system, which is composed of the one-dimensional trapped-ion motion and a single cavity field mode. In the present scheme, computation basis is composed by the internal ionic state and the cavity state by the connection of motional state. Furthermore, Lamb-Dicke limit is not required.
