    "abstract": "We present an alternative scheme for the generation of a 2-qubit quantum gate\ninteraction between laser-cooled trapped ions. The scheme is based on the AC\nStark shift (lightshift) induced by laser light resonant with the ionic\ntransition frequency. At {\\it specific} laser intensities, the shift of the\nionic levels allows the resonant excitation of transitions involving the\nexchange of motional quanta. We compare the performance of this scheme with\nrespect to that of related ion-trap proposals and find that, for an\nexperimental realisation using travelling-wave radiation and working in the\nLamb-Dicke regime, an improvement of over an order of magnitude in the gate\nswitching rate is possible.",
