An exact controlled-NOT gate with a single trapped cold ion is usually implemented by sequentially using three laser pulses. Here, we show that two-step laser driving is sufficient to realize such a gate, as long as the initial phases and durations of the applied laser pulses and the relevant Lamb?Dicke parameter are properly set.
