The motion of a cavity in spacetime generates quantum gates via entanglement between cavity modes. While entanglement produced by uniform acceleration is small, we show analytically that two-mode quantum gates with an observable amount of entanglement can be generated by periodic repetition of any non-uniform trajectory segment. A resonance occurs when the frequency associated with the duration of the repeated segment equals half the frequency sum of any two oddly separated cavity modes, leading to an entanglement accumulation that grows linearly in the number of segment repetitions.
