    "abstract": "Several sequential operations are usually needed for implementing controlled\nquantum gates and generating entanglement between a pair of quantum bits. Based\non the conditional quantum dynamics for a two-ion system beyond the Lamb-Dicke\nlimit, here we propose a theoretical scheme for manipulating two-qubit quantum\ninformation, i.e., implementing a universal two-qubit quantum gate and\ngenerating a two-qubit entangled state, by using a pair of simultaneous laser\npulses. Neither the Lamb-Dicke approximation nor the auxiliary atomic level are\nrequired. The experimental realizability of this simple approach is also\ndiscussed.",
