摘要： 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 $\Lambda$-type ions as memory instead of the vibrational mode. And the system is robust against the spontaneous radiation and the dephasing.
