We propose a scheme for the implementation of remote controlled-NOT gates and entanglement swapping via geometric phase gates in ion-trap systems.The proposed scheme uses the two ground states of the A-type ions as memory instead of the vibrational mode.And the system is robust against the spontaneous radiation and the dephasing.
