We propose unified scheme to realize optimal 1 3 symmetric economical phase-covariant cloning (EPCC) and optimal 1 3 symmetric economical real state cloning (SERS) in the context of an ion-trap system. In this approach, the vibrational mode is not used to act as memory and the two cloners work without ancilla, thus it is likely to be much less sensitive to noise and decoherence. By adjusting tunable time parameters, our system can also perform optimal symmetric (asymmetric) universal quantum cloning and optimal symmetric (asymmetric) phase-covariant quantum cloning. Based on the advancement of experimental technique in an ion-trap system, the scheme is feasible and the symmetric economical state-dependent cloning is optimal.
